What is an RV water pump?

An RV water pump is an equipment that moves water from its source to supply water to your RV. It is an essential part of the RV’s plumbing system . Its main purpose is so that water will reach your faucet, shower, and toilet whenever you need it.

The RV water pump uses the hydraulic principle to generate sufficient force for its use. This pump usually uses AC or DC power to provide energy to the motor of the water pump so that it can perform its job.

How does it work?

RV water pumps work on demand. This means, they’ll start working when you need them to. They follow a simple process when you turn them on.

The RV water pump works by putting pressure on your pipes. The amount of pressure is predetermined according to the pump’s PSI setting or pound per inch. The usual setting for RV water pumps is 30 PSI.

But there are RV water pumps that allow you to adjust the PSI settings according to your desired water pressure level. This type of water pump is preferred by many because it’s very flexible and can be adjusted according to your need.

When you turn on the RV water pump, it will start pumping water and it’ll continue to do so until you close the valve that controls the release of water. This can be your faucet, shower, or other water outlets. Once you turn off the valve, the water pump won’t immediately stop pumping. It will gradually stop until it reaches the preset water pressure on the pipes.

When you have the newer model of RV water pumps, the pressure on the pipes or water lines in your plumbing system remains the same or consistent. The pressure level will only change when another water outlet is opened. And if it detects any drop in pressure, it will start pumping again to be able to bring back the water pressure to the chosen setting.

Older models of RV water pumps don’t work this way. They rely on manual operation. If you need fresh water, you will open your faucet then manually turn the water pump on so that it will perform its job of bringing water to your faucet. Once you’re done, you need to turn off the water pump then close the faucet.

This sounds very inconvenient, right? Well, you also have to take note that you have to follow these steps to a tee or else you might experience some awful consequences. You have to remember that your manual RV water pump won’t stop pumping unless you turn it off. If you forget it turn it off, it can lead to overheating which could then cause bursting pipes and your rig will be flooded. You can imagine the rest of the story. Bottom line is, it will be stressful.

So, be thankful that we have modern RV water pumps that simplifies the entire process and automatically shuts down the water pump when you turn off the water outlet.

What are the different types of RV water pumps?

The RV water pumps that you can find in the market today usually come in 2 types. There’s the 12V water pump and the 24V water pump. Here’s how they are different so that you’ll know which one suits your needs.

12 Volt Water Pumps

The 12V water pump is the more common type of RV water pump. It comes standard in most RVs. The pressure in 12V water pumps is enough for the lighter water needs of RV users.

12V water pumps are the recommended water pump for RVs. They will get the job done of supplying you with water that you need and at the same time, they won’t cost too much so you won’t be shocked about your water and electric bills.

24 Volt Water Pumps

If you need more than the usual water pressure, then you’re going to need a 24V water pump. But these are more commonly found in trucks and buses instead of RVs.

24V water pumps can guarantee high flow to your water outlets and they are more reliable too. However, take note that since they require more power to run, there would be a surge in your water and electric bill.

RV water pump voltages: which is the best for you?

So, it’s really about determining the water pressure level that you need. Do you require more pressure are you okay with the standard level?

Take note that 24V water pumps cost more than 12V water pumps and your bills will also be higher so we recommend that you stick to the standard if you don’t really need the additional pressure. Sometimes going higher might do you more harm than good.

How to install an RV water pump?

The installation of an RV water pump would depend on the model that you’re buying. The steps could differ across different models and it’s best to follow the manufacturer’s instructions regarding the proper installation of their RV water pump.

But to give you an idea if what you’re going is right, here are the basic procedures in installing a new RV water pump.

Step 1: Make sure that your water tank is empty.

You can do this by connecting a water hose to the base of your tank. Open the valve to be able to flush out all the water from the tank. We recommend that you put the water in a large container so it’s not wasted. Just direct the hose into the container so you can use the water later on.

Once the tank is empty, you can now detach the link of the old water pump to your water tank.

Step 2: Disconnect the old RV water pump.

Before you do this, it is recommended that you disconnect the battery of your rig first. You should also disconnect the hoses which are connected to your old water pump. Then, with the help of your screwdriver, remove the wires from your old water pump. Look for the red and black wires as these are the usual wirings used to connect water pumps.

Remove the bolts and screws used to keep the water pump in place so that you can finally take off the old RV water pump.

Step 3: Put the new RV water pump into place.

Position the new RV water pump right where the old one used to be. Again, with the help of a screwdriver, secure the water pump in place using the bolts and screws. Make sure that the screws are tight. You can also wrap Teflon tape around the pipe threads.

Next, proceed to connect the inlet and outlet hoses at their respective locations then secure them in place by using clamps.

Step 4: Reconnect the wiring, battery, and water tank.

First thing you need to do is ensure that the link of the water pump to the water tank is reconnected. Make sure it is fastened tightly before anything else. Next, reconnect the electrical wiring. Once done, you can now reconnect the battery of your rig to be a power source for your new water pump.

Step 5: Test the connection.

This is your way of checking if you’ve installed the new RV water pump properly. To do this, you simply have to start your rig and check if the new water pump is working. You should be able to hear a sound which will tell you that it’s on standby and ready to be used.

If you don’t hear any sound from your new water pump, it might mean that something is wrong so you better check your electrical connections. Make sure that the connections to the water pump are right. Check also if your RV battery is properly connected.

Step 6: Test the water pump.

The next thing that you need to check is the water pump itself. To confirm that it is working properly, you can partially fill the water tank and turn it on. This will make it easier for you to check for any holes and leaks.

If there are no issues, turn on a water outlet such as your faucet. It may take some time before water comes out of your faucet as your new water pump is still filling your pipes with water before it comes out of your faucet. If water does come out of your faucet, then you’ve confirmed that your new RV water pump is doing its job!

That’s it! Your new RV water pump is ready to use. We would just like to reiterate that you should consult the manual first for specific installation instructions from the manufacturer. There might be slight variations according to the model of your water pump and those steps would be crucial to the proper functioning of your RV water pump.

What to Look for When Buying an RV Water Pump 

Now, allow us to help you find the best RV water pump for your rig. Here are the key criteria that you should carefully consider before buying an RV water pump.

Noise Operation Level

Noise has always been an issue among RV water pumps. Given the limited space within a rig, the noise level of a water pump could affect those inside the rig. That’s why you want a device that doesn’t make too much noise as it does its job.

There are some RV water pumps which can be loud when they are operating. It is to your best interest to stay away from those units so that you can enjoy a peaceful and relaxing time inside your rig.

Look for an RV water pump that has a minimal noise operation level even when multiple water outlets are open at the same time. Check the mounting type as there are some that can absorb sound to minimize the noise level. You can also look for a pump that has a 5-chamber design which can effectively bring down the noise level even when there are multiple water outlets that are open.

This stands for gallons per minute. The water pump’s GPM tells you how many gallons of water it can pump in a given minute.

You can usually find RV water pumps with 1 to 4 GPM. This is a good range to stick to as it will guarantee high quality performance of your water pump.

If the water pump has less than 1 GPM, it means that its performance is too weak while those with more than 4 GPM may be too powerful for your rig to handle. Those pumps with more than 4 GPM are also more expensive to use. Expect your water and electric bills to go up!

As discussed earlier, there are 2 types of RV water pumps: those that come in at 12V and 24V.

12V RV water pumps are the standard water pumps for rigs. They can get the job done efficiently with just enough level of pressure that can supply your rig with the water that you need. This won’t cause any issues within your pipes.

But there are cases when RV owners require extra pressure especially if you have a large rig. It is when you can go with a 24V water pump. These are more powerful and you can rely on its performance to supply all your water outlets with high flow of water. But take note though that it comes with a higher water and electric bill since it requires more power.

It is important that you understand which type of water pump will fit your particular needs.

PSI stands for pounds per square inch. Each RV water pump has a PSI rating and it is important that you choose a water pump that matches the recommended rating by your RV manufacturer. So you better check the manual of your RV for compatibility.

You will find RV water pumps with ratings of 60 to 75 PSI. This is what we call the safe zone when talking about water pressure in our rigs. Take this into consideration together with the recommendation of your RV manufacturer to be able to choose an RV water pump that’s safe to use for your rig.

Vertical suction lift

This is another important factor to consider when choosing the best RV water pump. Vertical suction lift refers to the specific amount of water that the water pump needs in order to operate efficiently. Some would need more water before it can function properly.

It is best that you look for an RV water pump that requires minimal amount of water to perform its job so that you can be assured that it will operate efficiently even with a little lift.

As with other equipment and appliances we put in our RVs, size does matter. Space is precious so we need to maximize every bit of space that we have.

Check the location where you will put your RV water pump and figure the size that you need. A water pump with a bigger capacity comes in a bigger size. Make sure your new RV water pump will fit in the given space.

Energy Efficiency

Take note that RV water pumps require power in order to do their job. They consume a specific amount of electricity and given that power is also a limited resource in a rig, you better check the energy efficiency of the water pump that you’re planning to buy.

There ahs to be a balance between the power it needs and its electric consumption. Your water pump needs enough power to be able to supply your rig with a good flow of water. But at the same time, it shouldn’t consume too much electricity because you also have other appliances and devices that share with your source of power.

Ease of Installation

As with any device you buy for your rig, you should consider its ease of installation. Will it give you a hard time to set it up? Do you need professional assistance or need someone else to help you?

We recommend that you buy an RV water pump that has a simple installation process. One that you can accomplish by yourself and lets you deal with fewer parts so that it’s easier to install. It’s also best if it already comes with the materials that you need for the installation such as Teflon tape, screwdriver, and water hose.

These are the main criteria that you have to consider when buying a new RV water pump. Make sure you go through each one carefully so that you will be happy with your purchase and it matches what you need in your rig.

RV water pumps are essential to your rig so you better take your time in choosing the best RV water pump for your rig. Take advantage of all this information that we’ve presented to guide you in your choice or maybe you can consider those items in our product review if they suit your needs.

We hope you’ll be happy with your purchase and won’t be hounded by water supply and flow rate issues for many years to come.

Frequently Asked Questions

What is the psi or the flow rate of the pump.

As mentioned earlier, PSI refers to pounds per square inch. This is a rating given to each RV water pump and will tell you about its performance level. You should look for ratings between 60 and 75 PSI so that you’re sure that its water pressure is within the safe zone as recommended by most RV manufacturers.

The water pump’s flow rate refers to the amount of time that it takes for the RV water pump to be able to pump a certain amount of water using its motor. This is usually measured by GPM or gallons per minute. A water pump with 3.5 GPM will be able to supply the needed water inside a camper or travel trailer. But for larger RVs, you would need a water pump with at least 5.3 gallons per minute.

What is an on-demand pump?

On-demand pumps or demand pumps are pumps used to be able to send water to a point of use from a water storage tank. These pumps allow users to control the movement of water and have it supplied when they need it and where they need it.

On demand pumps work by being able to detect a drop in pressure which happens when a faucet or a showerhead is turned on or when someone flushes the toilet. The drop in pressure activates the on demand pump to work and supply water to the particular outlet that needs it.

An RV water pump is a kind of on demand pump. It means that it only runs when you need it to. It puts pressure on your RV water pipes based on the predetermined PSI setting. Once you turn the RV water pump on, it will begin to pump water to be able to bring it to water outlets which are open. Once you turn it off, it will go back to the preset PSI and will shut down on its own. It will maintain this level of pressure until it detects that a water outlet is opened in which case the water pump will start pumping again.

What is included in the water pump?

If you’re wondering what is included when you purchase an RV water pump, it would really depend on the manufacturer. Some include everything you need for the installation while some only come with just the unit itself. Some suppliers will have you buy the hardware and accessories separately which makes it inconvenient for buyers.

It is better to buy from manufacturers that include all the fittings and accessories that you need to be able to set up your new RV water tank.

Why is my RV water pump so loud?

Some say that noise is a part of the operation of an RV water pump. If you’re having a new RV water pump installed, the noise of the motor running is oftentimes a good indication that your electrical wirings are connected properly.

But if the noise operation level gets so loud that it’s bothering you, then it’s possible that there is something wrong with the RV water pump. It could be indicative of a faulty design or an issue in the manufacturing of the product. This is why we advice you to buy from trusted brands because there are some companies who cut back on the cost of materials in the production of the unit.

When this happens, it results in poor product quality. This could make the unit difficult to install properly and you’ll encounter mounting issues which could cause it to make noise. Since it’s not positioned properly, it can cause vibrations, clanging pipes, and water hammering.

If mounting is not issue, you can also check if you’re experiencing rapid cycling. This happens when there is too little air charge inside the water tank. The water pump is not able to function properly which could cause vibrations on the unit and along the pipes. Better check the air pre-charge setting or cycle setting and make the necessary adjustments.

Another thing you should look into when your water pump is operating with a high noise level is the amount of water inside the tank. You might need to increase your water storage capacity. It might not be able to store enough water and you might need to install an accumulator that’s compatible with your water pump.

How to make an RV water pump quiet?

If your RV water pump is unusually noisy, you have to find out what is causing it to make such noise. What you need to do is to turn off the water pump then find the screws which secure it in its place. You have to remove these screws then place a mouse pad or similar material under the pump before you put the screws back on. Make sure that the screws are not too tight nor too loose. The mouse pad will help a lot in reducing the vibrations.

If the noise is coming from your water pipes, you need to find the specific pipes which are making this noise. You should get someone to help you with this task. Ask that person to turn a water outlet on and off as you locate the rattling pipe. Once you’re able to identify it, you would need a half inch foam insulation so that you can wrap it around the rattling pipe. Do this for all rattling pipes that you find. This should be able to stop the noise.

If the issue is that your water pump cycles too fast, it means that there is too little air inside your water tank and this could also cause vibrations or a noisy water pump. To resolve this, you need to make some adjustments on the settings of your water pump. You can turn the adjustment screw clockwise so that you will be able to increase the setting until such point that your pump runs with an off time of a minimum of three seconds.

How long does an RV water pump last?

Is it bad to leave water pump on in rv, how to install an rv fresh water pump, how long should an rv water pump run.

When you’re not connected to city water, it is safe for you to turn on your RV water pump and let it run for as long as possible. This is alright since RV water pumps operate on an on-demand basis and the water in your rig will be pumped from the onboard holding tank. It will pump water when you need it to. It will run when you flush the toilet or turn on your shower. But if no water outlet is open, your water pump won’t run and it won’t consume power.

But when you’re hook up to city water, it would cause some issues if you keep your water pump running all the time. The pump could be pumping in city water that’s unregulated.

How to repair an RV water pump leak?

Since RV water pumps operate on an on-demand basis, if it runs continuously even when there’s no demand, you know that there’s a problem. It could be a leak which your pump interprets as an open water outlet. This needs to be addressed immediately.

You have to find out what’s the cause of the leak. Usually it boils down to 2 reasons: 1. the check valve is broken; or 2. there are cracks along the water lines.

Here are the steps you need to follow to repair an RV water pump leak.

When the check valve is broken

Step 1: Pull the valve off the hose

Turn off the water pump and water outlet. Then remove the old check valve located at the hose that connects it to your rig’s freshwater tank. Just pull the valve off using your hands, nothing complicated about it.

Step 2: Disconnect the old check valve

Again with just the use of your hands, you should be able to detach the old check valve from your water pump.

Step 3: Install the new check valve

Now that you were able to remove the old check valve, you can replace it with a new check valve. Just put the new one right into the tube or hose that connects it to the freshwater tank. Take note that the directional arrow on your check valve should be pointing towards the direction of your RV water pump.

Once your new check valve is already fitted to the hose or tube of the freshwater tank, connect the other end to your RV water pump. It should slip right into place without any problem and that’s how you replace an old check valve.

When there cracks along the water lines

Step 1: Visually inspect for cracks

If there’s no problem with your check valve, then there might be cracks along your water lines or pipes that’s causing your RV water pump to leak.

Check all the lines connected to the water pump and look for any sign of cracks.

Step 2: Place a Bucket Under the Cracked Water Line

If you see a cracked water line, put a bucket underneath the connection of the cracked line and the water line to be able to contain the flowing water.

Step 3: Loosen the connection between the water line and the water pump

If water comes out when you loosen the connection between the water pump and the water line, it could mean that there’s really a crack. However, when no water comes out, it doesn’t necessarily mean that there’s no issue. It could mean that there’s a suction problem instead.

A suction problem usually occurs when there’s little or no water in your water tank. To rule out any suction problem, fill the tank with some water and attach the water pump. Turn the pump on and test the water line again.

Step 4: Fix the cracked water line

If the problem is really about having a cracked water line, then you need to repair it immediately.

Turn off the water pump. Using a pocket knife, cut out the cracked portion of the water line. You should have a plastic tubing on hand and cut out a portion that has the same measurement with the part that you’ve just removed.

If you don’t know what kind of plastic tubing to get, just inquire with your trusted RV supplies store.

Step 5: Patch up the water line

If the plastic tubing that you got has a lot of slack in it, you can patch up the water line with just one fitting. But if your plastic tubing doesn’t have any slack, it’s best to use two and attach them together before you put them on the water line right in the spot where you cut the old portion.

Leave it to dry for about 12 to 24 hrs. Once it’s already dry, you can turn on the water pump again and observe what happens. It should be able to solve the issue and you can expect that there won’t be any leaks anymore.

Keep in mind that it’s best to ask for professional help if you don’t have the skills to perform these tasks. This is true especially when you can’t figure out anymore what’s wrong with your water pump. Let them check your water pump and with their expertise and experience, they can have your pump running efficiently in no time.

The 7 Best RV Water Pumps

You’ve seen the summary, now it’s time to see the full story. Ahead are the individual reviews of the best water pumps for RVs on the market.

Prepare for a journey through a seasoned pro’s expert advice complemented by hilarious zingers. All to prepare you for the much grander journey ahead.

Best Overall

1. Seaflo 55 Series Water Pump

• Shut-Off Pressure: 60 PSI
• Flow Rate: 5.5 GPM
• Size: 8.5″ x 5.8” x 5.2”
• Weight: 6.09 lbs

Value meets versatility in our top pick: the Seaflo 55 Series! It’s my personal choice for the best RV water pump. However, I’d also say it’s one of the best value 12V water pumps you’ll find with variable speed technology out there!

The Seaflo 55 meets the needs of most RV enthusiasts and full-time RVers. Featuring Variable Flow Technology , its impressive 55 GPM flow rate and 60 PSI cut-off are capable of powering up to five appliances simultaneously. And ALL with regulated pressure (and a built-in pressure switch of course).

But despite all this fancy tech on offer, you’re still looking at a very comfortable mid-tier price point for a top-tier water RV pump. In fact, you’d be hard-pressed to find another RV water pump this cheap that includes the same bang for your buck. This variable speed pump even offers durability features that include:

• Low-flow cycling prevention
• Thermal protection
• Self-priming function

Truly, the Seaflo 55 Series does it all. And all stacked into a deceptively quiet 5-chamber diaphragm!

Overall, there’s a lot of good that can be said about the Seaflo 55 Series and not a lot of bad. There are some reports of shoddy customer service. They’re rare though, and the product has a 4-year warranty to back it up which is excellent. I can tell you from personal mid-trip horror stories that these are important considerations. Even the best water pumps for RVing are fickle creatures!

Otherwise, the Seaflo 55 Series is a well-priced and well-rounded, quiet water pump for basically all RVs and campervans. A five-fixture capacity is enough for most full-time RVlifers and oodles for part-timers. And all that cash you’ve saved on its digestible price tag can go straight into the road trip budget!

Best Splurge

2. Remco Aquajet RV Series Water Pump

• Shut-Off Pressure: 65 PSI
• Flow Rate: 5.3 GPM
• Size: 10” x 4.8” x 4.6”
• Weight: 8.01 lbs

While the Seaflo 55 Series pump will service most RVers, the Remco Aquajet is for anyone who wants the best of the best RV water pumps. Though similar in stats, the Aquajet edges out the Seaflo in areas of size, power, and even noise level. This thing is a silent but deadly beast!

The standout feature that separates the Remco from the pack is its advanced circuitry. This allows the water pump to automatically control motor speed and maintain optimal water pressure, even if using multiple fixtures at once. This guarantees zero chance of rapid cycling.

Remco, however, has dedicated special attention to the noise levels of the pump. Or more specifically, the lack of noise. Remco boasts that the Aquajet RV Pump is a whopping 90% quieter than other diaphragm pumps on the market. While reports suggest those boasts may be greatly exaggerated, it’s still certainly a contender for the quietest RV water pump available with this level of power.

But… it’s big. And it’s expensive. Even with all the durability and premium features of a top-shelf RV water pump, you need to want it. It won’t fit in all RVs. It might also be overkill and suck too much power from smaller RVs. You have to plan for this purchase.

As a budget nomad who prefers campervan-style RVs, I can say that the Remco is not for me. It’s very unlikely to suit fellow RVers who prefer a dash more dirtbag in their travels. For those RVers, the Seaflo 55 or the next pump on this list is a much better option. 

But for full-time, big-time RVing in style, you can’t do much better than the Remco Aquajet. It’s the best RV water pump you can get this side of 12 volts!

Best Budget

3. Shurflo Precitrade 2088

• Shutoff Pressure: 45 PSI
• Flow Rate: 3.5 GPM
• Dimensions: 8.6″ x 5″ x 4.5″
• Weight: 5.5 lbs

So, speaking to my fellow frugal travelers now, here is the best budget pick. The Precitrade Shurflo 2088 balances a very manageable cost with a level of quality that still rivals our top picks. In my travels, I’ve learned that affordability shouldn’t mean missing out on key features, and this water pump proves it.

In comparison to the other budget pump-up next on our list, the Shurflo Precitrade packs more POWER. Its solid 3.5 GPM flow and 3-chamber diaphragm design ensures consistent flow and operation across multiple appliances. Plus the built-in check valve does a fabulous job preventing any reverse flow. 

Finally, this cheaper RV water pump still self-primes up to nine feet! I can tell you from my own admin days cursing at my hand tools that a feature like that helps a lot with installation.

But it’s not all sunshine and showers! While it does have enough power for most casual RV users, it still doesn’t hold up as strongly in real-use scenarios as the Seaflo 55 or Remco Aquajet does. And it’s also significantly louder than you’d want a water pump of this power level to be.

If the Remco is a bit too premium and the Seaflo 55 sounds just a tad excessive for your style, then this Shurflo water pump might be your Goldilocks’ porridge – just right! It still packs a lot of top features, including thermal protection, without the heavy price tag.

But if you need more than the Precitrade can give, opt for the first two picks on this list. Alternatively, if you want a similar price point at a quieter level, try our next pick.

Best Budget Alternative

4. Pentair Shurflo Revolution 4008

• Shut-Off Pressure: 45 PSI
• Flow Rate: 3.0 GPM
• Size: 4.9” x 8.1” x 4.3”
• Weight: 5 lbs

The next budget water pump for RVs clocks in at a very similar price to the Shurflo Precitrade. Stats-wise, it’s also very similar. However, by sacrificing a little bit of power and functionality, the Shurflo Revolution offers a more quiet experience. This quieter water RV pump is tailored for those who prioritize tranquility in their on and off-road adventures.

The aptly titled Revolution offers innovation in its whizz-bang technology. Its unique one-piece diaphragm design paired with an internal bypass enables smooth and consistent water flow with more peace and quiet. This bypass valve also safeguards your RV’s plumbing system from excessive water pressure.

Furthermore, this RV water pump self-primes up to six feet. Again, this is less than the Precitrade but enough to still help a lot.

The comparison between the two budget picks is clear. More power or more serenity. Personally, I opt for quieter RV water pumps like the Revolution. But I’m big on my middle-of-nowhere, dead-silent camping. If you’re looking for a budget pick but need more power, go for the Precitrade.

Of course, neither will be able to go toe-to-toe with the heavy hitters on this list. They offer higher power, more robust self-priming, and more durability too. They’re still the recommendation for people living full-time in their RVs.

But if you want quality at a very fair price and would prefer to hear the sound of a babbling brook over a grumbling water pump, the Shurflo Revolution is for you. Or, if all of these options are still too much power and cost, try our next choice!

Best Single Appliance

5. Seaflo 21 Series Water Pump

• Shut-Off Pressure: 35 PSI
• Flow Rate: 1.2 GPM
• Size: 6.5” x 3.8” x 2.5”
• Weight: 1.3 lbs

The Remco Aquajet was the best 12V water pump you can buy at a steep price. But what about the complete other end of the spectrum? The Seaflo 21 Series is the budget choice for the frugal road warrior. Especially when a simpler way of van life is your style!

This thing, by comparison to all the other pumps on this list, is SO much cheaper and smaller. But it’s only suitable for operating one appliance at a time. That’s going to wildly affect who this water pump is suited for. 

As it’s the same series as the top pick – the Seaflo 55 – you’re still getting a lot of value. Just without as much of a kick! The flow and shut-off pressure are significantly lower, as is the self-priming feature (up to four feet). It’s also got a very low power draw and is super compact making installation a snap.

However, the pump is still equipped with protection mechanisms and has a high-quality Seaflo-style build. Plus the lower water pressure makes the Seaflo 21 Series one of the quieter RV water pumps on this list.

But keep in mind that with that sort of flow and power draw, you’re not going to be able to run much more than simple sinks and other small appliances. This is the exact kind of water pump I’ve opted for in my more grungy travels. It’s best for very simple campervans that have low overall water needs.

Big, luxury road-mansions running multiple fixtures at once will want something like the Remco Aquajet. You could use it as a standalone backup pump for one appliance you want to run separately. But really, the Seaflo 21 Series is for singular appliances and one at a time. It’s better suited for budget adventurers with cheaper tastes in simpler styles… 

The valiant dirtbags of the van life.

Best Warranty

6. USA Adventure ProGear 3200

• Shut-Off Pressure: 55 PSI
• Flow Rate: 3.3 GPM
• Size: 4.85” x 9.10” x 4.55”
• Weight: 4 lbs

We’ve looked at a lot of the best water pumps for RVs so far. But up next is the USA Adventure ProGear 3200, and it’s not just another water pump: it’s a commitment. Offering a lifetime warranty, it’s a clear frontrunner for those who prioritize long-term assurance in their gear purchases.

Performance-wise, it doesn’t pack the same level of power as the Seaflo 55 or Remco Aquajet. However, it still packs more into its build than the budget picks. Furthermore, alongside its promise of durability, it boasts a 3-chamber diaphragm pump and self-priming capability of up to 10 feet. It’s also got a check valve that ensures no backflow and guarantees a smooth and hassle-free operation.

But when stacked against the competitors, what truly sets the ProGear 3200 apart isn’t just its performance metrics. It’s the peace of mind. Its comprehensive warranty backed by consumer support is a testament to the company’s confidence in its product and its unwavering support for its customers.

While many pumps can deliver efficient performance, few offer a lifelong safety net. I said it once and I’ll say it again, RV water pumps are fickle things! A few too many blow-ups on the roads have taught me that pumps that offer reliability and long-term security, like the Progear 3200, matter. For that reason, it’s a very strong contender.

In summary, the USA Adventure ProGear 3200 is the embodiment of commitment. Now, thoughts of commitment might give most nomads an allergic reaction (myself included!), but we should be more open to these things when they concern the gear for our rig. For RVers who value longevity, invest once in this RV water pump and rest easy knowing you’re covered for life.

Best For Quietness

7. Lippert Components RV Water Pump

• Shut-Off Pressure: 50 PSI
• Size: 10.5″ x 6″ x 5.5″
• Weight: 4.5 lbs

For those who crave tranquility during their RV journeys, the Lippert Components 12V RV Water Pump is an oasis in a vast landscape of noisy pumps and campsites. While many pumps claim to be silent performers, this water pump truly takes the crown in the realm of hushed operations. Some customers report that it’s so quiet they forgot to turn it off and burnt out the electric motor!

Don’t let its silent demeanor fool you though. This RV water pump delivers admirable flow and performance. When pitted against other top contenders like the Seaflo 55 and Remco Aquajet, this water pump doesn’t quite match up. But if we’re talking consistency, serenity, and value, it most certainly does match up, and it exceeds the budget choices in all areas as well.

But it’s the quiet operation that truly elevates this water pump. This pump prioritizes peace, allowing RVers to enjoy the natural ambience without the constant hum and reminder of our RV maintenance to-do list.

Of course, it is still significantly less powerful than the Seaflo and Remco. It’s not the best pick for large full-power van-sions or big family RVs where multi-fixture capability is a necessity. But for RVers who wish to merge efficiency with serenity, this pump sets a gold standard. With this pump onboard, you get more than water…

You get tranquility on wheels.

What To Look For When Buying a New RV Water Pump?

Setting out on the open road in your shiny to not-so-shiny RV is an unparalleled adventure! But it’s absolutely crucial to ensure your mobile abode is equipped with the essentials first. As someone who has done both pumped and pump-less RV living, I can’t stress how much easier daily life is with a high-quality water pump that can pump water from my freshwater tank to anywhere I need.

But RV water pumps come with a lot of technicalities that may perplex the less mechanically minded. Before you go buying, let’s dive into EXACTLY what you need to look for.

Water Pump Flow Rate (Gallons Per Minute)

The pump’s flow rate tells you how fast water gets delivered. Think of it as your pump’s speed. The more gallons per minute (GPM), the higher your flow and the more effective your appliances are. Variable speed pumps like the Seaflo 55 Series can adjust their flow rates to suit your needs.

I’ve found that a rate of 3 to 5 GPM works very well for most RVing, even full-time. It’s enough for getting yourself and the dishes squeaky clean!

Water Pressure (PSI)

Water pressure matters! Imagine wanting a strong shower but getting a weak dribble. The water pressure goes hand in hand with the water flow to define your experience.

Aim for a pump with a water pressure of 30 to 50 PSI to really boost your RV’s multi-fixture capacity. And consider the auto-shutoff too! This sets the benchmark for what water pressure the pressure switch shuts off at to improve the pump’s lifespan as well as defines what the maximum water pressure is.

Size of Pump

Space is a luxury in an RV. Always check the pump’s dimensions before buying. I always make sure it fits my storage/installation area. 

Remember, size matters only relative to your needs (hurhurhur) . A bigger pump isn’t always better. Go for what fits or what isn’t going to be a pain in the gluteus maximus to install.

Unless you enjoy the sound of Autobots transforming in your peaceful camping adventures, take into account the RV water pump noise. A quiet evening can be ruined by a loud pump. 

Check for pumps with a low decibel rating. Or browse the reviews to see what users say. But do expect some noise – nothing’s perfect.

Thermal Protection

RVing can take you across all kinds of climates. From the Nevadan deserts to the Coloradan peaks, temperatures will vary wildly! 

Thermal protection stops the pump from overheating or freezing. It’s a small feature, but it’s saved me from pump troubles too many times to count.

Our Verdict

H-2-whoa , you are ready to go! (With the flow.) By now, I hope you’ve found the best RV water pump for your needs. Because you won’t find any better than the RV fresh water pumps on this list!

It really does come down to your needs though. At the end of the day, what matters is that your RV’s water pump can deliver water from your fresh water tank to wherever you need. There are pumps for single appliances. There are pumps that prioritize longevity. Some prioritize serenity. It’s about what YOU need.

The top pick remains the Seaflo 55 Series . It’s the best combination of all factors that matter in an RV water pump. It’s got durability, power, and efficiency, and weighs in at a very respectable price point.

Alternatively, if not even the Seaflo 55 can service your road warrior needs, try the Remco Aquajet . This proverbial beast is better suited to the road paladins. Full-time RVlifers in big, hulking luxury rigs will need a pump to match that energy.

And if none of these pumps work, you can always try to go full dirtbag with the by-the-river living. I’ve done plenty of that too! But I can tell you after your fifth round of freezing cold bucket showers, you’ll either be aching for a better setup or yearning for a city water connection.

So get a pump and get clean. Be a dirtbag in spirit only. But in your hygiene and in your travels, be a cleanbag. With a whizz-bang and oh-so-sexy RV water pump.

H-2-Over and out.

To put it plainly, an RV fresh water pump is a pump that is designed for use in recreational vehicles such as campers, travel trailers, and motorhomes. The device’s job is to bring fresh water from a storage tank to shower heads, sinks or toilets. 

Water pumps for campers are typically 12 volt pumps , and as the name suggests, they wire directly into the 12 volt system of the RV. 

These are different from a 110V water pump or 120V RV water pump, which are generally designed for residential purposes and generally installed in homes. While a 12 volt water pump for RV obviously doesn’t pump water with the same high pressure as larger residential models, they get the job done for recreational vehicles.

While 12 volt water pumps work with a variety of power sources, including electric, solar and fossil fuel, RV electric water pump is by far the most common and easiest to maintain type , especially while traveling.

An RV water pump consists of several components: a pump itself and the fittings which are required to hook up to your RV’s water system and the wires to hook up to the 12 volt electrical line of your RV system. 

The fittings can come either as a threaded type unit. This one attaches with wing nuts, and can be a bard, either a straight or an elbow and the other one uses fittings called a squad port which works by having a couple of O-rings on the bottom of this fittings.

They literally plug into the pump and lock in place. The quad ports are also available in a variety of threading types of even bards, elbows or straights.

In the course of operation, water pumps for RV draw water from the storage tanks and distribute it throughout your RV to the water appliances.

These pumps usually work on-demand , thus are also called 12 volt on demand water pump . There is a pressure switch on the head of the pump which allows it to turn on and off automatically based on the operation of the appliances. 

For example, when you open the faucet in the galley, the switch is going to tell the pump to turn on, and when you close the faucet it tells the pump to turn off.

• Save space inside recreational vehicles: Compared to the traditional water pumps, water pumps for recreational vehicles are relatively small and lightweight. Hence, such pumps allow RVers to preserve space which is by all accounts a luxury. 
• Maintain a constant water supply: With a 12 volt on demand water pump onboard, you could keep the water appliances of your rig running around the clock. That is by all accounts a big plus since your level of comfort on the road would be greatly enhanced. 
• Open up additional travel options: If you secure a solid water pump for your rig, you don’t have to worry too much about water supply as you plan your trips, compared to the worst case scenario of having to rely on expensive bottled water. As a result, you should be able to try out previously unconsidered routes and gain new experience in the process.
• Simple installation : Unlike the more complex residential water pumps, RV water pumps are easy to install, even a beginner camper can do it. The only thing you need to do is simply consult the manual.

Top-Rated RV Water Pumps

Due to individual liking, the best RV water pump to certain RVers could appear mediocre to others but you should pay attention to the models below if you want to get your money’s worth.

Why This Is The Best

As an RV on demand water pump that could be mounted vertically as well as horizontally, Shurflo 2088-554-144 works well in various settings.

Compact and light, the water pump made by Shurflo proves to be a breeze to set up and it has rather undemanding maintenance requirements too.

Because of that, Shurflo 2088-554-144 is considered to be the best RV water pump on the market for casual excursions nowadays.

The Shurflo pump is also offered at an affordable price so it suits the shopping budgets of lots of people.

Surfaces that come into contact with water in Shurflo 2088-554-144 are made of polypropylene/santoprene so the water that it delivers is safe for human consumption.

Since the water pump from Shurflo employs a thermally protected motor, overheating is going to be less of an issue.

Shurflo 2088-554-144 incorporates a solid check valve as well, hence, enthusiasts of RVing don’t have to worry about reverse flow.

Boasting a flow rate of 3.5 GPM and a pressure limit of 45 PSI, the pump of Shurflo is capable of keeping water running around the clock.  

In terms of post-purchase support, Shurflo backs its water pump with a decent 1-year warranty that covers manufacturing defects.

If you like to have an insurance policy while buying things, you should think about adding Shurflo 2088-554-144 to your shortlist.

Finally replaced my aging SHURflo 2093-544-114 in my Lance truck camper. This new pump holds pressure longer and the pump turns on less than the old one as it brings lines back up to pressure much faster. This pump is actually very quiet and efficient. Wrapping the water lines in foam is the secret to reducing the vibrating sound created by all 12v water pumps. Now there is ample pressure for a nice shower. Simple to install. Release pressure on water lines and unscrew hoses attached to old pump. Unscrew the four screws holding old pump to wall under the sink and remove. Attach hoses to new pump and screw pump back onto wall under the sink. Using a cordless power drill with a phillips screwdriver bit makes this install much easier as there is often little room to get your body and arms inside the cabinet to turn the screws. Buy on Amazon and easily install this yourself and you will save money on not only the pump but the labor costs at your local RV service center. I saved $20 on the pump and at least $85 for an hour of labor at local RV store. The old pump lasted 20 year and I expect this new pump will give me the same or even better service life.

• Long-lasting
• Flexible and versatile
• Packaging needs some work
• Some RVers complain about occasional leaks

Why It’s An Editor’s Choice :

Dependable and reliable, Flojet 03526-144A is held in high esteem by many enthusiasts of RVing.

Possessing a top-of-the-line automatic triplex diaphragm, the Flojet pump works like a charm in plenty of environments.

In addition to that, as Flojet 03526-144A integrates corrosion-resistant material, it handles elements well.

Unsurprisingly, once it comes to full-time RVing, the pump from Flojet tends to be regarded as one of the finest models available for purchase.

Thanks to the presence of a pulsation eliminator, Flojet 03526-144A is able to eliminate the need for an accumulator tank and keep the noise down.

The pump from Flojet utilizes a mount designed to absorb sound too which means RVers should barely notice it running.

As a result, if you look for a tranquil outdoor experience, Flojet 03526-144A would be the best RV water pump that you could pick up.

Though its flow rate is indeed unexceptional, the pump made by Flojet is still by all accounts a good buy.

As for installation, Flojet 03526-144A features convenient snap-in fittings so the setup process only takes a couple of moments.

Being a self-priming model, the Flojet pump has outstanding suction lift compared to the average pumps for recreational vehicles.

Replaced the original pump in our motorhome with this one and have a great increase in flow and its a lot quitter than the old one. Install was simple even though I had to remove the outdoor shower to access the pump it still only took about an hour and a half and that included draining the water tank. The price on Amazon was a lot less than I could find any replacement RV water pump locally and it arrived in two days. It shuts off smoothly and the water flow is constant with no sputtering. Time will tell if it stands up over several years but initially I am very happy with it. Shared by Scott in Sparks

• Robust operation
• Straightforward installation
• A few pumps arrive damaged
• Less than ideal quality control

Looking for a basic pump? If that is so, it’s strongly recommended that you check out bayite BYT-7A102.

While its flow rate falls behind other models, the bayite pump still comes in handy in an assortment of setups.

By integrating precision ball bearings for long life, bayite BYT-7A102 makes sure that it would be years before you have to find a replacement.

The motor of the pump made by bayite also has a built-in thermal breaker that keeps it from overheating.

Due to a combination of sealed switch and electro coating that inhibit corrosion, bayite BYT-7A102 could maintain constant operation even in high humidity conditions.

However, it’s worth noting that the water pump of bayite is unable to withstand water submersion so be careful.

Aside from that, as BYT-7A102 boasts soft rubber mounting feet that provide ample cushion from vibration, it usually lets out few sounds in use.

Assuming that it’s installed correctly, bayite BYT-7A102 should guarantee years of quiet operation.

Prior to being delivered, water pumps of bayite would be thoroughly tested one last time. Thus, in the case that you notice water traces in your bayite BYT-7A102, there is no cause for concern.

This worked great for pumping water into an RV tank. Where we camp, there are no hook-ups, so I connected a hose on either end and used this to pump water from portable water containers into the RV using a hose connector. It was pretty fast and easy to use. I had to pour water into the hose going to the pump first to get it primed, and then it worked great the rest of the way. Shared by D982

• Sublime suction strength
• Limited flow rate
• The pressure switch should be redesigned

Why We Love It:

Engineered to be a heavy-duty pump, FloJet 4406-143A could be put to use in a wide range of applications.

Capable of delivering 3.2 gallons of water per minute at up to 30 PSI, the pump from FloJet would allow you to freely use the amenities on your rig all day long.

Buying an RV Water Pump: Key Criteria to Consider

To get the best RV water pump for your rig, you must consider these most important buying criteria before making a purchase. That said, if you’re limited by your budget, choose a model that offers the best balance of different features and benefits. After all, the best RV water pump really depends on your budget and water consumption needs, which might depend on factors such as the number of companions you’re travelling with. 

As RVers count on the pumps to deliver water to multiple amenities throughout the vehicles, GPM is deemed to be one of the top concerns. By checking out the GPM rating of a pump, you could tell how much water it’s capable of supplying. Pumps on the weaker end may have GPM ratings of 1.2 or so, while the best RV water pumps would typically have a GPM ratings of more than 4, making them 12 volt high volume water pump .

In the case that the water consumption of your rig is moderate, you may settle for a standard water pump. On the other hand, if the amenities on your rig require lots of water then it’s strongly recommended that you prioritize high GPM models.

PSI is another measure of pressure rather than flow. RV plumbing systems are built to handle pressures between 40 and 60 PSI, so it’s best to get a 12 volt water pump with a PSI within that range. Any pumps that advertise a higher pressure rating than 60 PSI might cause damage to the pump itself and your RV plumbing system.

Amperage, or amps, is another metric you should pay attention to when hunting for the best RV water pump. It measures the amount of electricity a water pump needs to draw in order to work. If you need to power many energy-consuming appliances in your rig, you might want to double check that your power sources can handle the daily total amps drawn. While most RV water pumps draw very little electricity, 12 volt high volume water pump can draw up to 15 amps of power.

In the average recreational vehicles, space is limited which is why it’s essential that you pay attention to size while shopping for a pump. The last thing you want to spend your money on is a huge travel trailer water pump that your modest rig is unable to accommodate. So as to grab a fitting pump, you should think about the available space inside your rig and decide accordingly. Until you know for sure that you have the space for the pump you like, avoid committing to a purchase.

Technically, it’s fine to drive your vehicle to a nearby workshop and let the professionals take care of the pump installation in your stead. Still, as an RVer, you likely have to deal with many expenses so why don’t you pick up a camper water pump that you could set up by yourself? By installing the pump on your own, you would save some bucks for more pressing needs and potentially learn how to perform proper maintenance too. To determine the installation complexity of a particular RV pump, you must assess its design and read reviews of customers.

Typical RV water pumps run on electricity so before you put a certain pump in your vehicle, don’t forget to check its power requirement. Today’s market contains two lines of water pumps for recreational vehicles: 12V and 24V. Your choice will depend on the amount of water you need pumped and the size of the RV. 

Keep in mind that a 12 volt unit is more manageable as it draws less power from the system and generally does its job in the RV setting. A 24 volt pump translates to high volume, but it could drain your RV’s battery or generator.

All in all, having a strong pump is pointless if you fail to keep that pump powered adequately in use. Thus, to find the best RV water pump for your vehicle, you have to take into account its power supply.

The best RV water pump should start pumping once the pressure goes below the preset level  and also stop pumping automatically once the pressure reaches the preset level. This automation, or automated on-off cycling, allows for consistent performance. 

If your pump does not cycle on and off as demand arises, it will continue to run when it isn’t really needed, which can cause damage to your RV’s plumbing line and also significantly increase your energy consumption.

In the long run, a pump that continues to run all the time will have a much shorter life than one that cycles on and off as needed.

So you wish to enjoy your outdoor experience in peace? Then you need to consider giving noise level some thoughts. All pumps make sounds during operation, especially during pump cycles, but plenty of models nowadays control the noise relatively well. To get a quiet RV water pump , it’s key that you keep an eye out for models that incorporate specialized noise-reduction materials as well as low-vibration mount. 

There are useful tips to make your pump run more quietly too. Sliding a small pad beneath the pump before securing the screws down is a simple yet effective way to minimize vibration when it’s running. Another simple tip is to not overtighten the screws.

Some pumps run noisily as they cycle rapidly. This is usually caused by a low-pressure setting and can be fixed with a minor clockwise turn of the pressure adjustment screw. Only remember to adjust this setting until your pump turns off for at least two seconds between cycles.

Unlike residential models, RV water pumps are engineered so that they can receive water from a limited water source. The best RV water pump should have self-priming feature, which will allow it to pump water from the tube even when the water supply is running low. Also, this feature will prevent the pump from getting damaged even when it’s running dry.

As mentioned above, 12 volt water pump for RV can be categorized by its power source, including fossil fuel, solar power and electricity. Another way to differentiate them is by their pumping speed. 

The most common type of 12 volt water pump for RV is the constant speed pumps, which, as their name suggests, deliver water at one speed only. Basically, these pumps are either off or on. 

Variable speed pumps, on the other hand, can create water pressures similar to that in your home. Their built-in pressure sensor adjusts the speed of the pump motor to ensure the water is delivered at a constant pressure. 

In addition to this advantage, they also tend to be quieter, although you’ll have to spend more for these benefits compared to their constant-speed counterparts.

Finally, 12 volt high volume water pump models are designed to deliver water at a higher rate of flow than the standard 12 volt water pumps that come built-in on most RVs. 

A pump is considered “high volume” if it’s got a flow rate of more than 4 gallons per minute (GPM). To achieve this, they typically require more electricity to operate, so they’re usually found only on larger, 50-amp rigs. If you travel often and with companions who might wish to use water at the same time, getting a 12 volt high volume water pump will be ideal.

For your information, there are also 24-volt pumps typically installed in trailers, buses, and trucks that have higher water pressure for more heavy-duty tasks. However, they will take a toll on your RV’s power. This is why 12 volt pumps are the most common type for RV you will come across. 

Top RV Water Pump Brands

If you know exactly what you’re looking for and found a model that suits your needs and budget, feel free to go with a lesser known manufacturer, given that the model you’re buying gets good RV water pump reviews .

To be on the safe side, it’s best that you follow the user’s manual that accompanies your water pump while setting it up. That being said, if you need a general installation guide, check out the following steps.

Step 1: Drain The Water Tank

You must connect a hose to the base of your water tank and proceed to drain it all the way. It’s a good idea to direct the hose to a drum so you could reuse the water once you finish setting up your pump.

Step 2: Remove The Old Pump

First, you should disconnect your old pump from the battery bank by removing the wires. Next, you need to pull out all the hoses connected to the pump as well. Following the removal of the wires and the hoses, you have to work on the securing bolts and screws that fix the pump in place. After everything is out of the way, gently lift the pump out of your RV.

Step 3: Secure The New Pump

Put the new pump into the position of the old pump then bolt it down. Additionally, you also need to wrap up the pipe threads with some Teflon seal tape.

Step 4: Reconnect The Wires/Hoses

If the pump seems to be well-secured then you could start reconnecting the wires as well as the hoses. For good measure, it’s strongly recommended that you check all connections again at the end prior to moving on.

Step 5: Test Out The Pump

Your water new pump should be operational at this point so you only have to flip the power switch and see how things turn out. Pay attention to odd sighs and make corrections if necessary.

FAQs About RV Water Pumps

To put it plainly, an on-demand water pump is a pump that kicks on the very moment water is demanded and moves that water from a storage tank to the intended point of use. It has a control unit built inside so it knows exactly where water is needed. The operation of on-demand pumps is based on the pressure in the water pipes. As people open faucets, flush toilets and so on, RV on demand pumps would continue to supply water until pressure in the pipes returns to a predetermined parameter. Depending on the models, the pressure threshold could be adjusted up and down. https://youtu.be/DZWq7fpFXKo

The answer to that is yes. The RV pump is what creates, pressurizes and make the water move. So the rating on the pump says 5 gallons per minute or 3.5 gallons per minute is the output capacity of the pump. Once you hook it to your distribution system, chances are you’re not gonna get 5 or 3.5 GPM because the water’s gonna travel through pipe, it’s gonna travel through elbows, fittings and your faucet fixtures. The important thing is that you have enough flow, enough pressure to make it workable in your RV.

A 12 volt water pump for RV typically lasts up to 10 years, and the best RV water pumps with solid construction can last well beyond that mark, given that you have installed and used it correctly and give it proper maintenance.  Sometimes, though, it just depends on pure luck. The best you can do is get a model with good reviews, from a prestigious manufacturer and with a fairly long warranty, which by the rule of thumb is a good measure of the product’s functionality and durability.

You may need to prime your RV water pump after replacing it, or if your RV’s been out of use in storage for quite some time. The process is simple, as follow: Fill up your fresh water tank. Turn on the cold water faucets in your RV, make sure they are completely open. Switch on the water pump near your RV water tank. This should prime the pump by pushing water up from the tank through your faucet. Let the water flow a while, then turn the faucets off. Note that air must be completely removed from each and every faucet. You can do this by opening and closing the faucets, as well as the showerhead and toilet, one at a time to run water through each.  Your pump will be fully primed when the water pump only turns on when a faucet is actually open and not in between.

Your RV water pump uses pressure switches to start and stop working. If this switch is not set properly, pulsations occur. The more sensitive the pressure switch is to the change in pressure caused by turning on the faucet, the fewer pulsations. Most pumps have an ideal setting that can minimize or almost eliminate pulsations.  To make the switch more sensitive to the change in pressure, make the pump start quicker and run longer. The water pressure will therefore stay steadier, reducing the frequency of pulsations. 

Yes you can. As it is a pressure sensing device, the water pump will only turn on when there is demand for water, and it only pumps water on demand.  It’s good to know though that many RVers recommend turning the pump off at night to prevent possible sleep disturbance. Every couple hours or so the pump relaxes it’s pressure just enough to run the pump for a second to bring the pressure back up, which can disturb the light sleepers.

The most common symptoms that your water pump is not working properly and might need replacement are: Runs when not in use: If your water pump continuously runs or keeps cycling on and off when not in use, while you have confirmed that water is available to the pump, the pressure switch might be faulty. Or else, This might be due to something as simple as a loose connection or a crack in one of your plumbing lines. Pump runs but no water from faucets: Ater making sure that there is actually water in your freshwater tank, check all the water lines that lead in and out of the actual water pump. Look for loose connections and worn, split or cracked lines. Next, check if there is any problem with the plumbing lines by seeing if there is water flowing to the pump. Start by carefully loosening the water line to the pump. If you disconnect it and the water line seems dry, then the issue is the actual water line coming to the pump from the tank. Deal with any type of blockage or tube damage.  If there is still no water, the problem lies with the pump itself. Examine it to see if the motor is faulty and needs to be replaced, or else you will need to replace the whole unit. Especially when another assistant turns the water pump on again, and the water only comes out in small drips, you most likely need to get a new water pump.  Excessive and unusual noise: Most of the RV pumps have a multi-chamber diaphragm design which over time can become corroded or calcified rendering them inoperable. Improper winterization can also damage the diaphragm creating increased noise and very low water pressure. Otherwise, the culprit might be motor failure. Leaks: In this case, check the fittings and connections as well as the pump housing to make sure the issue is indeed caused by the pump and not something else in your plumbing line. Won’t Turn On: First, make sure you didn’t leave the drain open when you meant to be filling up the fresh water tank. Next, check your 12 volt fuse panel, then move to the pump and look for the possible use of an inline fuse. Next, check the electrical connections on the pump and then move to the pump switch to see if it’s still functional. Then, use a multimeter to check if power is actually making its way to the pump. It might be that you winterized your RV last winter, now it’s spring and the pump is not working. In this case, make sure you reconnect everything correctly after you pumped RV antifreeze through the water lines. If nothing resolves the problem, it’s time you get a better RV water pump replacement .

To silent a loud pump, you have lots of options. By slipping some foam pads under the pump, it’s possible to isolate the vibrations and keep the noise down. In the case that source of noise seems to be rattling water pipes, you should wrap foam pads around them. Many pump manufacturers also sell dedicated, purpose-design pump silencers that let you reduce the noise level of your pump.

Just like every other device, RV water pumps require periodic maintenance in order to stay in top shape. To preserve a consistent flow of water, you should remove and clean the filter of your pump now and then. If you often let your RV sit idly for months, it’s essential that you sanitize your pump at intervals to remove algae build-ups. Finally, during winterizations, stick to nontoxic antifreeze to protect the integrity of your pump.

Best RV Water Pumps

Hey! This site is reader-supported and we earn commissions if you purchase products from retailers after clicking on a link from our site.

Having a functioning water pump is essential for any full-time RVer. While you’ll likely spend some time hooked up to city water and campground systems, life on the road doesn’t always have this convenience available. For your RV to have running water when away from these hookups , your RV water pump ensures that what’s in your freshwater tank can get to your sink, toilet, shower, and other places.

When your RV water pump happens to break, it can cause all sorts of inconvenience. Sometimes, you can solve the problems with repairs, but other times you’ll need a replacement part to get things back to normal. If your situation is the latter, then our guide to the best RV water pumps can help you make the best purchase to keep your RV livable.

Our Top Water Pumps for Your RV

A deeper look at the recommendations we’re pumped about.

Ready to learn more about our top picks? Check out our in-depth review of our favorite water pumps for RVs.

Best Overall 12 Volt RV Water Pump

Shurflo 2088-554-144 fresh water pump.

The choice that wins our pick for the best RV water pump is SHURflo’s 2088-544-144 model. This product gives steady water pressure, which is what you want out of this part of your RV. It’s more than earned its place as one of the top-rated RV water pumps on Amazon by customers.

Not only is the SHURflo 2088 a high-performing water pump, but it’s also simple to install. You only need to connect a few wires and pipe fittings, and you can complete the process in ten minutes, even if you’re new to adjusting the parts in your RV. The price is also affordable for the quality you’re receiving – the perfect fit for a full-time RVing budget .

One of the few cons of this water pump is that it runs rather noisy. However, you can fix this issue by also purchasing and installing a silencing kit or even using some foam cushioning.

Check Price

• Easy installation
• Affordable price
• Reliable water pressure
• Highly rated by RVers
• Can be noisy

Best High Volume Pump

Pentair shurflo 4048.

When living in an RV full-time, you’ll likely find yourself wanting to run multiple faucets at once. The Pentair SHURFLO 4048 makes that level of operation possible thanks to its high-volume output. You can get water from various places at once without worrying about the pressure dropping out.

The high levels of output make this pump suitable for RVs that host large groups of people at once; you won’t have to worry about strategically planning your schedule for showering, washing dishes, and other tasks again!

For all its positives, this water pump is a constant speed model, so you will need to turn it on and off as it goes in and out of use, which can be inconvenient. Additionally, the high volume capacity requires a circuit with a fifteen amp fuse, which may require some upgrades if your RV doesn’t already have the necessary equipment.

• Provides high volume of water output
• Allows running multiple faucets at once
• Four gallons per minute
• Runs constantly
• May need a power circuit upgrade

Best Variable Speed Pump

Remco aquajet.

Many RV water pumps require that you turn them on and off when they’re in use; otherwise, you risk draining your power. A variable speed model doesn’t need that, as it can adjust its output to use. The Remco Aquajet is the top model in this category, providing a smooth and consistent water pressure that adapts to whatever faucets you need to run.

This pump also runs quietly, so it won’t disturb your regular RV life when it’s in use. For those who care about where their RV parts come from, Remco manufactures their products entirely in the United States.

While it doesn’t require as much energy as others in our top picks, this water pump requires a ten amp fuse, so there’s the potential that you might need to upgrade your RV’s electric system to use this part.

• Variable speed model can stay on at all times
• Smooth and consistent pressure
• Made in the USA
• May require a power circuit upgrade

Most Affordable RV Water Pump

Arterra pdsi-130-1260e.

If you need to purchase a new water pump without breaking the bank, then Arterra’s PDSI-130-1260E model is our top budgeting choice. While you don’t want to sacrifice quality to pay a lower price, that won’t be the case with this product. The water pressure and overall performance will serve you well while living in your RV, and it can handle regular use.

This water pump is also on the smaller side, so there won’t be fitting issues for most RVs out there (though you’ll still want to confirm the measurements!). The overall installation process is also simple, with a few hookups that will quickly settle into your RV’s system. With such a quick job, you can swap out your parts with as little hassle as possible.

Be aware that some customers find that this pump makes a bit too much noise for their tastes. Again, you can solve this issue by using a silencing kit or other means, though, so it’s not such a massive problem to have.

• Highly affordable
• Simple installation
• Small size is convenient to fit into your RV
• Some users have sound level issues

Buying an RV Water Pump: What to Look For

All RVs are different, and the needs of one full-timer, while sometimes similar, likely won’t match up precisely to those of another. Aside from selecting a quality product, you want to make sure that the one you choose matches up with your RV and water needs. Here are some areas to think about as you shop to make the best possible purchase you can.

Gallons Per Minute (GPM)

Water pumps have a set capacity for how much water they can push through your pipes at a time. Since this spec can vary between models, you need to pick out one that’s suitable for your RV’s water system . Have a rating that’s too low, and you won’t get the water flow you need to get the best operation from your sink, shower, etc.

However, you don’t want to overcompensate and get a water pump with a GPM spec that’s more powerful than your water system needs. Parts with more power behind them take more energy to run, and you don’t want to overtax your electrical system and batteries for no useful reason, especially since that can add extra expenses to your full-timing budget.

Water pumps mostly come in twelve and twenty-four-volt options. Higher voltage generally indicates more GPM.

You won’t need much more than a 12 volt water pump for RV usage, so you can stick to that rating without worries of overtaxing your electrical system!

Without a functioning and reliable motor, you won’t be getting much use out of your water pump otherwise. With this factor, you want to ensure that the part will last long enough to be worth your money; the more effective the pump is at doing its job, the less strain it will go through while in use, meaning it can have a greater lifespan, expanding how long it will take to need a fresh replacement.

Additionally, consider your motor of choice’s noise level as well. Preferably, your water pump will operate quietly. One that’s too loud isn’t desirable when you have to live with it in close capacity.

Noise Level

Water pump motors produce noise that could be really annoying if the pump doesn’t have great sound blocking around it. Water pumps with a 5-chamber design tend to be the quietest models. Wherever you mount your water pump, you can also look into putting in some sound deadening material to cut down on the noise.

Just like you’ve seen in the list of our top picks, water pumps come in constant flow and variable flow options. You don’t want to ignore this factor in your shopping as it will impact the ease of use and other areas in your RV.

A constant flow water pump is always running, which means that it can take up a lot of power from your RV’s electrical system. You can turn them off, but then you need to turn it on whenever you plan to use the water, and it does take some time for the pump to warm up enough to give you steady water pressure.

On the other hand, a variable flow pump will work very similarly to a pressurized water system in permanent homes. They adjust the water pressure based on how much they’re in use, which gives smoother water flow while also using less overall power – they’re even quieter than their constant flow counterparts. However, the downside is that all that convenience leads to a heftier purchasing price.

If you can afford a variable flow pump, they’ll be well worth the expense while living full-time in your RV, where continually having to turn the water on and off can be a hassle. For those who’d prefer to save the money, though, a constant flow model will get the job done, especially if you pick a high-quality one.

PSI (Pounds per Square Inch)

Another stat you want to pay attention to for your water pump is paying attention to its psi measurement – which indicates the level of water pressure. Much like the motor capacity, you want the pump to match the needs of your RV.

Thankfully, most water pumps aimed at RV usage fall in the range of sixty or seventy-five psi, which is safe for most motorhomes. It’s still best to check your RV’s owner’s manual before picking out a pump, just in case.

Vertical Suction Lift

Vertical suction lift is all about efficiency. It refers to the amount of negative pressure on the suction end of the pump. Essentially, how hard is your pump working to get water through your appliances?

Energy Efficiency

Make sure to check the energy efficiency certifications of the water pump before you make a decision. You don’t want this appliance to be a huge drain on your battery.

Installation

As full-time RVers, performing your maintenance is essential for keeping your home in good shape and also sticking to your budget. Those circumstances likely mean that you’ll be installing your water pump on your own, so you want to make sure you can handle the process as smoothly as possible.

When selecting a water pump, pay attention to what fellow RVers have said about the installation process to give you an idea of the process and also keep an eye out for products that have unnecessary attachments and components. Our RV expert, Brian , can also help you out in this department. He recently wrote an article on how to prime an RV water pump that should give you a good idea about the installation and priming process.

Something else to look out for is the size of your replacement water pump since this factor can vary between models. If you purchase one bigger than your previous water pump, then you likely won’t be able to fit the new one into your RV – not a situation you want to be in if you’ve already done the work of removing the previous part.

If you can upgrade your water pump to a larger size, it can have better performance. However, you don’t want to aim for so massive an upgrade that you can’t make use of it!

As with any other purchase, you should always plan to buy a new RV water pump with a clear budget in mind. Especially for full-timers, every section of your budget counts, and you don’t want to go overboard and put a strain on other financial areas of your life.

Frequently Asked Questions

What is the best rv water pump.

The best water pump for your camper is going to depend on all the factors we mentioned above: gallons per minute, the motor, noise level, flow type, PSI, vertical suction lift, energy efficiency, how easy it is to install, size, and your budget. However, after our research and testing, if you’re looking for a good 12v pump, we think the SHURflo 2088-554-144 Fresh Water Pump offers really good value.

How Long Does an RV Water Pump Last?

If your pump is properly taken care of, it should be able to last more than 10 years. However, there are a lot of factors that can shorten the lifespan of your water pump like cold weather, corrosion, or mistreatment (like leaving the pump running when there is no water left in the tank).

How Do I Know If My RV Water Pump Is Bad?

Most water pumps will have a warning light letting you know something is wrong with it. Some other tell tale signs that there is something wrong with your water pump are: it is making more noise than usual, it is leaking water into your RV, or it won’t turn on.

What Are On-Demand Pumps?

On-demand water pumps only run when it is necessary to run, which is pretty much how most modern RV water pumps operate these days. Once you flip the switch to turn the pump on, it will keep water flowing to any open faucets. Once you turn off those faucets, the pump will run for a short period longer to reach a desired pressure level and then shut off automatically until it is needed again.

What is an RV Water Pump?

RV water pumps are essential for the delivery of water from your freshwater tank to your faucets, toilet, and shower whenever you’re not connected to a water hookup.

Without one, you won’t have enough pressure to push the water through your RV plumbing system, so even if your tank has plenty of water, you won’t get much coming out of your faucet.

RV water pumps are specially designed for motorhomes, so they can easily run without using up all of your battery power. When you turn on your shower or faucet, your RV water pump detects the loss in pressure and automatically switches on to maintain pressure levels, giving you running water.

When you turn off your faucet, pressure levels no longer need to be maintained and your pump automatically powers off.

Best RV Water Pumps

Whether you’re looking to improve your RV water flow rates, or need to urgently replace your RV water pump, don’t settle for second best and potentially ruin your next trip.

Here are eight of the very best RV water pumps around – read on and find the perfect model for your rig right here.

Pentair Shurflo 4048 High Flow Pump

One of the very best RV water pumps on the market, if you need an upgrade to your RV water system, the Pentair Shurflo 4048 High Flow Pump is definitely worth considering.

Designed as a replacement for the 4900 and 5900 Shurflo Smart Sensor Series RV pumps, it also makes a great choice for larger RVs where you have multiple water outlets and need excellent pressure levels.

Thanks to its four gallon-per-minute flow rate and 55 PSI, you can shower, cook, and clean with ease and plenty of fast flowing water when you’re off-grid. With a 10-Amp draw, big rigs and medium-sized motorhomes won’t have any issues powering this premium RV pump, although for small popup campers and the like you would be better off with a lower performing pump that draws fewer amps.

Complete with a one-piece diaphragm and an internal bypass to reduce cycling, this pump provides a smooth, high flow with next-to-no noise, making showering in your RV almost comparable to your bricks and mortar setup. It is self-priming to six-feet, so you have plenty of options where you can mount it, and, importantly, it won’t get damaged if you run it dry. Back-flow is prevented by a built-in check valve to ensure maximum performance.

This pump is easy to install and you can rely on the manufacturer for help and guidance, should you run into any issues. While it isn’t the cheapest model, for superior flow rates and quiet, reliable performance, this is the very best RV pump for your class A or large fifth wheel.

Pentair Shurflo Revolution 4008 Series By-Pass Pump

If you are looking for a highly reliable, extremely quiet RV pump, but don’t quite need the high flow rates of the Shurflo 4048, then check out its sister model the Shurflo Revolution 4008 Series By-Pass Pump .

This model also features a one-piece diaphragm and internal by-pass system for top performance and high durability. With its 12-volt 7.5-Amp motor, you’ll have all the power you need for a three-gallon-per-minute flow rate with a maximum pressure of 55 PSI – comparable to your average home plumbing system.

Thanks to Shurflo’s Reaction Flow Technology, cycling is reduced, so you won’t have to worry about your plumbing system disturbing your day-to-day activities. What’s more, this RV water pump can self prime up to six vertical feet and run dry without any damage, as well as being fitted with automatic overheat protection.

An excellent choice for any RV with multiple water fixtures, this water pump is understandably a highly popular model. Durable, reliable, and quiet-running, if you need a replacement water pump for your RV, the Shurflo Revolution should be right at the top of your list.

Remco Aquajet Power RV Series Water Pump

For large trailers and motorhomes, the state-of-the-art Remco Aquajet Power RV Series Water Pump is a high-performance choice providing greater flow rates at high pressures, ideal for using multiple water outlet points simultaneously. It is also made in the USA and runs virtually silently.

Thanks to its advanced electronics, this premium RV water pump automatically adjusts its speed to match the flow rate required as you open and close your water fixtures. The Soft Start feature prevents rapid cycling and thanks to its five-chamber design, you get excellent flow and pressure rates – 3.5-gallons-per-minute and a positive shut-off at 75-85 PSI.

The five-chamber design also displaces more water per revolution of its motor than your standard three or four-chamber models. This not only means you get a better, smoother water flow, it also ensures that you won’t get a drop in pressure if you need to use the kitchen faucet when your other half is taking a shower.

With its superior hydraulic energy transmission, the Aquajet is much quieter than your standard RV water pump. Its patented screw-free diaphragm reduces pulsations that are common with inferior models for even less noise. Featuring low voltage protection and a maximum pressure bypass, your coach is also protected from excessive pressurization.

Installation is fairly easy, thanks to its universal mounting option. The pump includes two quick-connect fittings that are compatible with industry standards. On the downside, given its exceptionally strong performance level, this RV water pump is only really suitable for big rigs, as you may get surges that are too great for small campers and travel trailers with limited water fixtures.

On the whole, an excellent option for large fifth wheels and Class As, if you need superior performance and a virtually silent pump, then this RV water pump is the best choice, albeit at a price.

USA Adventure Gear Progear RV Replacement Water Pump

Are you looking for an RV water pump to replace your Shurflo Revolution? Or maybe a Flojet, Lippert, or Seaflo RV water pump replacement? This model by USA Adventure Gear has been specially designed as a direct alternative. Whether you are looking to upgrade your equipment or to save some money, it makes a good, dependable choice that is assembled in the USA.

Suitable for all motorhomes, the Progear RV Replacement Water Pump has a three-gallon-per-minute flow rate with pressures up to 50 PSI. Thanks to its one-piece diaphragm and in-built by-pass system, it has both the performance levels and durability that you need from your RV water pump.

This model is also thermally protected and can run dry without any damage occurring. As a self-priming pump, it has a maximum six foot lift and can be mounted in any position. CSA certified for use with potable water, this pump automatically turns on and off as required using water pressure.

Suitable for replacing most RV brands, this pump is easy to install, although as it only has three chambers, you don’t quite get the higher performance levels of some of the more expensive models.

What’s more, you may find it to be a little louder than premium versions. However, for medium-sized and smaller trailers and motorhomes, this handy replacement pump is a good all-round choice that will meet most user’s needs.

Lippert Components 12V Flow Max Water Pump

The 12V Flow Max Water Pump by Lippert Components is a good choice if you are looking for a value-for-money pump that’s situated at the mid-to-lower end of the price scale.

Suitable for all RV types, it has a three-gallon-per-minute flow rate with an average 50 PSI pressure rating, ideal for medium and smaller sized motorhomes and trailers. With its 9.5 Amp draw, there are lower alternatives around if you have a small camper and are worried about overpowering your RV Amp voltage.

The Flow Max runs pretty quietly, so it won’t disturb you. Despite its low-noise levels, it features a heavy-duty, corrosion-resistant motor to keep your RV faucets flowing. It is also certified by the CSA as being suitable for potable water.

This RV pump has a universal fit type for ease of installation, but do double-check compatibility with your current model and RV plumbing system before you buy. Self-priming, you can install it in a variety of locations to best suit your RV layout. Also, it can run dry without incurring any damage for a longer lifespan and greater dependability.

A good value buy, this pump comes complete with an included screen filter and connectors. However, bear in mind that the instructions state that it should only be used for five minutes at a time, then switched off for 10.

While there doesn’t seem to be much of a problem using it for longer, if you enjoy long showers and have multiple faucets in your RV, we suggest looking at our other replacement RV water pump recommendations.

Flojet Triplex Diaphragm Automatic Water System Pump

Another good value model, the Flojet Triplex Diaphragm Automatic Water System Pump is competitively priced at the lower-mid end of the scale. It comes with a Flojet strainer included, as well as easy to use snap-in port fittings for ease of installation.

With a respectable 2.9 gallons-per-minute flow rate and a maximum 50 PSI pressure, this is not the highest performance RV water pump, but it’s more than adequate enough for your camper or travel trailer. At 50 PSI it pulls a 7.5 Amp draw, making it less energy-intensive than more expensive versions.

Thanks to its soft noise-absorbing mounts, this RV water pump runs fairly quietly, for minimal disturbance. It also features a built-in bypass for less pulsation. Self-priming with an impressive nine feet suction lift, this pump can also run dry without occurring any damage.

Made from corrosion-resistant materials, this replacement RV water pump is a durable choice. However, bear in mind that it is not suitable for use with accumulator tanks and if used for a significant period of time it will shut down to cool off.

All in all, a good model for small RVs and campers, the Flojet Triplex gives you all the features you need at a good price.

SEAFLO 21 Series DC Diaphragm Pump

If you have a small camper or trailer, then the Seaflo 21 Series DC Diaphragm Pump could be the best choice for your needs. This compact RV water pump is also one of the most affordable in our selection, ideal if you need a budget replacement water pump for your RV.

Self-priming, you can run this pump dry without any damage occurring and it has a four-foot suction lift. With a fairly low 1.2 gallon-per-minute flow rate and a 35 PSI pressure rating, this pump is not very powerful. However, for a camper with a single water fixture or a trailer with up to two, this handy little pump will suffice.

Thanks to its built-in pressure switch, when you open your faucet the pump starts up automatically, then switches off again when you close it. Another advantage of this water pump for pop-up campers and small RVs is its very low power draw, averaging around 1.7 Amps, with a maximum of 2.7 – ideal for campers with limited power supplies.

Despite its soft rubber noise-reducing foot mounts, this model is still fairly loud when in use. Complete with thermal overload and ignition protection, this professional-grade water pump is safe to use.

While it is noisy and a little underpowered, if you need a compact RV water pump for your small camper or trailer, the Seaflo 21-Series is a good budget choice for supplying water to one to two standard ⅜” outlets.

SEAFLO 55-Series Diaphragm Pump with Heavy Duty Pressure Switch

This Seaflo 55-Series Diaphragm Water Pump features an all-new, heavy-duty pressure switch so that it automatically switches on and off whenever you turn your faucet on and off.

Easy to install, winterize, and service, if you are looking for an RV water pump with a high flow rate capable of supplying up to five fixtures, the Seaflo 55 makes a good purchase.

Self-priming, it can be run dry without damage and features a six-foot suction lift capability. Its fast 5.5-gallon-per-minute flow rate at a pressure of 60 PSI makes this pump one of the top performers, while costing considerably less than other premium versions.

Thanks to its five-chamber design, this pump provides a smooth flow with reduced cycling and high water volumes. It has a reasonable eight Amp draw, although this can rise to a maximum of 17 Amps. Ignition and thermal protection systems ensure this pump remains safe to use and highly durable. In fact, it also comes with an impressive four-year warranty.

With a built-in bypass function, rapid cycling is reduced, preventing the water from flowing back through your pump. If you need to supply four or five water outlets, then this high-performance RV replacement water pump complete with its heavy-duty pressure switch makes an excellent choice.

Buyer’s Guide to Buying the Best RV Water Pump

Cut through the technical jargon and find out just what you need to look out for when choosing your replacement RV water pump with our handy buyer’s guide.

Price can vary a lot between different types of RV water pumps. Obviously, performance is a huge factor, with premium models that have special designs and more costly components coming in well above standard, compact models.

Whether you need a pump for your camper or your luxurious fifth wheel, you should always match your needs to your pump before looking at the prices. Once you’ve established a list of suitable models, look through the prices and compare carefully.

Whenever possible, it’s preferable to pay a bit more for a pump from a reputable brand, such as any of those featured in our RV water pump reviews, to ensure that you get a high-quality product.

GPM – Gallon Per Minute

GPM is the measurement of your water flow rate in gallons per minute. In other words, the volume of water that flows through your system over a defined period of time.

On average, RV water pumps tend to have a flow rate of around three to four GPM, which is more than adequate for your average setup with two to four water fixtures.

Obviously, if you have a tiny popup camper, you can look at lower rates, or higher ones for large Class As with multiple water fixtures that are likely to be used simultaneously by large family groups.

PSI – Pounds Per Square Inch

The pressure provided by your RV water pump is measured in PSI – short for pounds per Square Inch.

You’ll need to match this to the safe operating pressure of your RV plumbing system. Pressure is a measure of the “force” of the water flowing through your system. Evidently, the higher the pressure, the better the flow.

Generally, RV plumbing is tested to high pressures around 100-125 PSI, however, manufacturers often recommend regular usage at around 40-50 PSI.

Ease Of Installation

For extra easy installation, you should opt for a direct replacement for your existing RV water pump. Like-for-like models, or those recommended by the manufacturer as new upgraded models to replace older systems will make changing over your pump much easier.

If you decide to install a different type of pump, you may have a more complicated task ahead. To make this as easy as possible, check your pump dimensions as well as your existing RV plumbing fixtures and fittings.

If you have any doubt over their compatibility with your new pump, don’t hesitate to contact the manufacturer for advice. Any brand that is deserving of your custom will be glad to assist.

While all pumps are going to make some noise, just how much can vary considerably between different models and brands.

Expensive RV pumps are often quieter as manufacturers tend to go to the trouble of trying to minimize noise to justify charging a premium price. You can also look out for soft molded feet and fittings that will help to prevent the vibrations produced by your pump from being passed on to your rigid RV plumbing lines.

When you’re replacing your RV water pump, it makes sense to replace it with a model that’s a similar size. If you choose a new pump that is much larger, you’re probably going to have to make quite a few changes to your plumbing lines to accommodate it.

Choosing a new pump with the same or a slightly smaller footprint will make switching over your RV pump a much easier and shorter task.

RV water pumps are generally 12V models, although you will find some 24V RV water pumps available. Only recommended for large setups, 24V versions require extra maintenance and draw a lot more power.

12V models are the norm, providing enough power to give you running water at comparable pressure to bricks and mortar plumbing. They also draw less, making them a much better option for when you’re not hooked up.

Vertical Suction Lift

Vertical suction lift puts a figure on your pump’s efficacy. It’s essentially the capability of your pump to produce a lower than atmospheric pressure on the suction line, to raise the water up and out of your tank to your faucet.

A pump with a vertical suction lift of say, four feet, can be placed up to four feet above the liquid level in your tank.

Your pump will cycle every time the water pressure in your RV plumbing system drops. The pressure setting can be adjusted directly on your pump unit.

If you find that your pump is cycling on and off too frequently, you may need to adjust the pressure setting to better correspond with your RV’s plumbing.

Energy Efficiency

Unless you are at a campsite with only electric hookups, chances are when you need to use your water pump, you’re going to be off-grid. That means you’ll need to make sure that you can run all of your essential appliances.

Every Amp counts, so be sure to factor in the draw of your RV water pump. Especially if you have a low power set up or, conversely, a lot of power-hungry appliances, such as AC units.

RV Water Pump Extras

Before you go ahead and install your new RV water pump, check out these pump extras.

While every pump needs a strainer to function correctly, you may also like to take advantage of swapping out your pump to make a couple of upgrades.

RV Water Pump Strainers

RV water pump strainers are highly recommended for keeping your pump in top condition. A pump strainer will prevent any foreign bodies from entering your pump and potentially damaging or even destroying its correct functioning.

Some RV pumps come complete with a strainer included, while others have them available as an additional purchase. Most are simply a fine mesh screen with removable housing that you simply attach onto the inlet side of your pump.

It’s important to clean your pump strainer regularly as part of your RV maintenance program.

RV Water Pump Silencing Kit

To reduce the amount of noise made by your RV water pump, you may wish to take advantage of replacing your pump and also install an RV water pump silencing kit at the same time.

Consisting of two flexible pipes that fit between your rig’s rigid plumbing lines and your pump, these kits effectively reduce the rattling noises that often occur when your pump is in use, preventing the pump vibrations from coming into direct contact with the lines.

RV Water Pump Accumulator

Installing an RV water pump accumulator is a great way to reduce pump cycling and ensure a smooth, constant water flow.

As most RV water pumps are constant speed, when you don’t require full flow from your showerhead or faucet, your pump will cycle on and off. It will run until the pressure is reached, then switch off, the pressure will drop, then come back on, etc.

Installing a pump accumulator is a little like having a reserve tank. It sits on the outlet side of your pump and ensures a steady flow. Your pump fills it up then will switch off, only switching back on when it needs to be filled up again, rather than constantly cycling on and off.

Benefits of an RV Water Pump

RV water pumps are pretty much an essential piece of kit, after all, we all need to wash, cook, and drink. Here are some of the main benefits of RV water pumps.

Easy to install – RV specific water pumps are easy to install. Before purchasing, double-check compatibility for the easiest installation. In most cases, compatible models can simply be swapped in a matter of minutes.

Even if you don’t choose the easy route, swapping like for like, an RV specific water pump is still going to be the easiest type of pump to install, as well as the most effective.

Save space – As with all things RV-related, RV water pumps are designed to save you precious space. Smaller and lighter than conventional water pumps, RV versions can be located in various places to ensure they take up the bare minimum of space.

Energy efficient – When you’re not plugged into shore power, you need to account for every Amp, especially if you’re running an AC unit.

As it’s not always possible or practical to run your generator for long periods, especially when you’re trying to enjoy the peace and quiet in natural surroundings, RV water pumps are specifically designed to draw a low number of Amps.

Save money – Buying bottled water is expensive and over time it will soon add up to over the cost of your pump. If your trailer has a shower, you’ll also be able to actually use it rather than paying to use a nearby campsite or truckstop one.

Freedom to explore – With on-board running water, you’re free to explore wherever the road takes you. Keep your tanks topped up en route and go exploring far from civilization, for comfortable off-grid camping.

Frequently Asked Questions about RV Water Pumps

When it comes to the water system in your RV, having a reliable and efficient water pump is essential. From providing a steady flow of water for cooking and cleaning to ensuring a refreshing shower or a flush of the toilet, an RV water pump plays a crucial role in your overall camping or travel experience. However, choosing the right water pump and understanding how it works can sometimes raise questions. To address any concerns you may have, we’ve compiled a list of frequently asked questions about RV water pumps. Whether you’re a seasoned RV enthusiast or a beginner just getting started, this FAQ section will provide valuable insights and help you make informed decisions about selecting, installing, and maintaining the best RV water pump for your needs. So, let’s dive in and explore the answers to some common queries related to RV water pumps.

What is an RV water pump?

An RV water pump is a device designed to provide a steady flow of water from your RV’s freshwater tank to your faucets, showers, and toilets. It pressurizes the water system to ensure a consistent and reliable water supply while you’re on the road.

Why do I need an RV water pump?

An RV water pump is necessary to distribute water throughout your RV’s plumbing system. It allows you to access running water for various activities such as cooking, cleaning, and personal hygiene while camping or traveling in your RV.

How does an RV water pump work?

RV water pumps utilize a motor-driven impeller or diaphragm to create suction, drawing water from the freshwater tank and pressurizing it. When a faucet or other water outlet is opened, the pump senses the drop in pressure and activates to maintain a steady flow of water.

What are the key factors to consider when choosing an RV water pump?

When selecting the best RV water pump, consider factors such as flow rate, noise level, power consumption, durability, ease of installation, and compatibility with your RV’s plumbing system. It’s also essential to determine whether you need a 12-volt or 110-volt pump, depending on your RV’s electrical setup.

How do I determine the flow rate I need for my RV?

The flow rate you need depends on your water usage habits and the number of fixtures in your RV. A general guideline is to aim for a flow rate of 3 to 5 gallons per minute (GPM) for smaller RVs and up to 5 to 8 GPM for larger RVs with multiple water outlets.

Are RV water pumps noisy?

Some RV water pumps can produce noise, but many manufacturers have made significant improvements to reduce noise levels. Look for pumps with noise-dampening features or consider installing additional noise-reducing materials around the pump to minimize sound.

How do I install an RV water pump?

The installation process may vary depending on the specific pump and your RV’s plumbing setup. Generally, you’ll need to locate the pump near the freshwater tank, connect the inlet and outlet hoses, secure the pump in place, and wire it to your RV’s electrical system. It’s recommended to follow the manufacturer’s instructions for proper installation.

Can I use an RV water pump with other water sources?

While RV water pumps are primarily designed for use with freshwater tanks, some models can also draw water from other sources, such as external water containers or campground hookups. Check the pump’s specifications or consult the manufacturer to ensure compatibility with alternative water sources.

How do I maintain an RV water pump?

Regular maintenance is important to keep your RV water pump in optimal condition. This may involve cleaning or replacing the pump’s filter, inspecting the connections for leaks, ensuring the pump is properly winterized if needed, and occasionally lubricating moving parts as recommended by the manufacturer.

What are some reputable RV water pump brands?

There are several reputable brands known for manufacturing quality RV water pumps, including Shurflo, Flojet, Remco, Jabsco, and Seaflo. These brands offer a range of pumps with varying features and specifications to suit different RV needs.

Remember, always refer to the manufacturer’s instructions and guidelines for specific information on the operation, installation, and maintenance of your chosen RV water pump.

Final Thoughts

If you’ve been putting off replacing your RV water pump, now’s the time to get it swapped over.

Whether you want to upgrade your RV water pump to improve your RV shower flow rate or just need a simple replacement, with our top-rated RV water pump reviews you are sure to find the very best pump for your rig.

The Pentair Shurflo Revolution is a highly popular model that is still good value for money if you are looking for a high quality RV water pump. From a reputable brand that you can trust, it is highly dependable, quiet, and effective.

For the ultimate upgrade, take another look at the Remco Aquajet Power RV Series Water Pump . This state-of-the-art model is made in the USA and runs virtually silently thanks to its advanced electronics that allow for automatic adjustments – ideal for using multiple water points simultaneously.

This is MyCamperFriend’s top pick for the best 12 Volt RV Water Pumps:

• SHURFLO 4008-101-E65

If you have a camper (from travel trailer to motorhome – doesn’t matter which one), chances are that you have a freshwater pump on board. And if that is the case, chances are that you’ll need a new one sooner or later. Maybe not. But could be.

Your RV water pump makes sure that you have a reliable source of fresh water when you’re not connected to a city water supply. It allows you to use your faucets, your toilet, your shower, etc. whenever you’re boondocking, for example.

No matter if you’re about to replace your old 12 Volt RV water pump or if you never had one and you’re about to install your very first one (which is undoubtedly the greater of the two adventures), this article will provide you with a list of the top choices you can find on the market and also explain a few things about RV water pumps in general.

There are far more complex topics when it comes to RVing but this one here might be challenging and confusing enough to steal your valuable time. My plan with this article is to give you time back by relying on my research and advice.

We’ll cover two main brands here: We’ll explore Shurflo RV water pumps (including a Shurflo Revolution water pump) and review a Flojet RV water pump.

Please note that we won’t specifically cover a 120V RV water pump or a variable speed RV water pump. And there’s no need for that, really, as the pumps on this page are all you need to make the right and best purchase decision.

RV Water Pump Reviews

After announcing our best overall RV water pump and showing you all pumps in one table, let’s now dive deeper and review each of the best 12 Volt RV water pumps.

All products below are 12 Volt electric water pumps that run at the same speed all the time. These are your typical 12 Volt water pumps. Nothing too fancy. Those are the models you need. Sure, there are even fancier ones that can adjust their speed as needed, for example. Those tend not to be as loud as conventional pumps and they can also do a better job to prevent the famous pulsing by providing you with a constant water supply. However, the products listed and reviewed on this page are in my opinion the products that work best for most campers and are the best solutions for most campers in terms of features vs. cost.

We have two major brands in the water pump business represented by the 4 water pumps I picked: Flojet and Shurflo (Pentair). You’re in very good hands there.

User-friendly

Easy installation & maintenance

Self-priming

Quiet operation

Reasonable price

Quality of clips could be better

Weighing only 2.6 pounds and measuring 9 x 4 x 4 inches, the  Flojet 03526-144A is our best “small” RV water pump in terms of its throughput: 2.9 gallons per minute (GPM).

This user-friendly, easy to use and maintain pump is self-priming (up to 9 feet suction lift), dry running and has three chambers.

The initial set-up should be easy thanks to snap-in 1/2″ port fittings.

The use of corrosion resistant materials makes the Flojet 03526-144A durable and your reliable pump partner for years to come.

This reasonably priced pump, which boasts with a with a pulsation eliminator / built-in bypass for less pulsation, does reduce the need for an accumulator tank as it runs smoothly due to the automatic triplex diaphragm it uses.

The soft mount is indeed capable of absorbing noise and so this pump is pretty quiet when it’s running. Anything that kills noise is truly appreciated on a relaxing camping weekend, isn’t it?

It has a 3.4 bar pressure switch setting and, thinking about it, the only things that could be better are the plastic clips to secure the port fittings. But that’s not a biggie to me.

This  Flojet 03526-144A is a good investment overall that will do exactly what it’s supposed to do. Therefore, it’s a safe investment for you.

With the 2.9 GPM this pump provides you with, this is the lowest throughput model reviewed on this page. You’ll have to find out for yourself if a GPM of 2.9 makes a huge difference compared to the 3.0, 3.5 and 4 GPM models further down on this page. I’d say it’s not much different than our overall best RV pump pick which is up next and has 3.0 GPM. Sure, you’ll probably notice a little bit of a difference if you compare it to the 4.0 GPM model below. But then that is more expensive. The net is if you want to get a very good lower priced RV water pump where the GPM doesn’t really matter, this Flojet RV water pump here is a wonderful choice for you.

This pump by Flojet  is reasonably priced, self-priming, user-friendly, durable, quiet as well as easy to install and maintain.

A very good one.

Good flow rate: 3.0 GPM

Reasonably priced

Check valve is built-in

Pump shut-off pressure is 55 PSI

Thermal overload shut-off

Works seamlessly for a lot of RVs

Doesn’t need more than 7.5A

Not the quietest

The Shurflo 4008-101-E65 is our overall 12V RV water pump top pick.

Shurflo products are very reliable and therefore widely used in RVs. Maybe your old one (in case you need a replacement and this is why you’re here) is a Shurflo water pump. When you talk water pumps for RVs – this is the brand.

This flagship product here weighs 5 pounds and measures 4.8 x 5.5 x 11.5 inches.

It is reasonably priced, has a decent 3.0 gallons per minute flow and the pump shut-off pressure is 55 PSI. The 3.0 GPM are just fine if you don’t put too much strain on your RV’s freshwater plumbing system. Meaning, if you don’t have the family consume water out of your RV’s faucets including the shower at the very same time, you’ll be fine.

The shut-off pressure switch is there to stop the thing if the water pressure it reaches is getting too high – this prevents your pipes from bursting. A good feature. Once it switches off, it will go back to 40 PSI when it’s back on. This back and forth can create what we refer to as “pulsing”. This phenomenon – in case it bothers you too much – can be addressed with an accumulator. See below for details on what that is.

Operating quietly and thermally protected, this reliable, self-priming Shurflo Revolution water pump with internal bypass valve / cycling d oesn’t need more than 7.5A. The former, the bypass valve, is here to manage some of that pulsing and cycling one typically experiences with water pumps. Thanks to this, the water pump is able to run and keep its pressure without cycling all the time. By the way, 62 PSI is the pressure that has that bypass valve all the way open. You can change the pressure switch and bypass valve settings if you wanted to. And the latter, the 7.5A, means – since this is not a whole lot of Amperage – that it is very likely that you can replace your current RV water pump without even having to adjust your electrical system / power source; that is something that sometimes comes with a new water pump. Probably not needed here. Very good. But you should obviously confirm this by checking your current specs.

And speaking about electrical things: A power circuit that has a 10 Amp fuse is required for this Shurflo diaphragm pump in terms of protection.

It makes sure to pressurize the freshwater system in your camper whenever you don’t have the luxury of being connected to a convenient city water source. The pump (4-chamber diaphragm pump design) can run dry (primes up to 6 vertical feet from the tank) and it also contains a check valve that is built-in. The job of the latter is to hold back the water from your city water connection (if connected to one at a campsite) so that it doesn’t flow into and fill up your freshwater tank – we don’t need that mess.

If you’re not into specs and technical details: What all of this translates to is that this RV water pump has what it needs to get the job done.

There is a 2-year warranty on this fine product.

Please note that you may have a pump controller (if you don’t have only one on/off switch for your pump). In this case, it’s really important to check and confirm the controller has the right size before you get and set up your new water pump.

Under the cons, I listed the fact that you can’t adjust the speed for this one here. It’s a binary affair – either it’s running or not. While it would be good if it slowed down when you don’t need the full force it can provide, this is no big deal really as it has no negative impact on anything really.

On the other hand, the pump surprises with really helpful features such as the thermal overload protector which shuts the pump down if it’s getting too hot. Only when it cooled down enough, it will turn back on automatically.

In terms of in and out ports, we have 1/2-inch 14 NPSM male threads here.

Check out the manual here if you’re interested in more details.

The user-friendly Shurflo 4008-101-E65 is our best overall 12V RV pump.

Easy to install and maintain, it comes with a good flow rate of 3.0 gallons per minute (GPM) which is usually sufficient.

This self-priming Shurflo pump is reasonably priced and has a check valve built-in.

Its pump shut-off pressure is 55 PSI and it even has a thermal overload shut-off.

A Shurflo diaphragm pump that works seamlessly for a lot of RVs and doesn’t need more than 7.5A is really an asset that you can’t go wrong with.

This is one of the most – if not the most – popular RV fresh water pumps on the market.

Sure, it’s not necessarily the quietest Shurflo water pump or water pump per se and it’s not a variable speed RV water pump. But those are not cons that would make me advise against a purchase. The pros really outweigh those minor flaws.

This is your pick if you want the best overall 12V RV water pump and if you’re able to spend a little bit more than the lowest priced pump on this page would cost.

Good flow rate: 3.5 GPM

Prevents reverse flow

Not the cheapest

Our third pump, the  Shurflo 2088-554-144 , is a bit stronger than our top pick above with its 3.5 gallons per minute (GPM) at 45 PSI pressure but maybe you wouldn’t benefit from a little bit more throughput anyway. It depends on your specific situation, how many people travel with you, how many of them consume water at the same time, etc. Lots of folks use freshwater water pumps with a GPM above 3.0. I rather consider myself a “water pump conservative” and think it’s best to get the one that is right for you regardless of what the GPM number is. If I like a pump that has a GPM rating that is a little bit (not too much) lower and I like all its other features, I’d go for it anyway.

The pump here, which uses safe polypropylene and other materials, weighs a light 5.35 pounds and measures 14.7 x 8.3 x 7.7 inches.

If you’re wondering what pump type this is, hold on to a handrail for this fancy term right here: It’s a positive displacement 3 chamber diaphragm pump. Whoa.

If you think that, with increasing GPM, the price also increases – yeah, sometimes that can be the case but this one here is still reasonably priced and definitely affordable.

The Shurflo comes with a 1-way operation c heck valve whose main responsibility is to prevent that reverse flow I explained for the top pick above.

A really good, thermally protected permanent magnet motor is behind this 12V DC water pump: Namely a P/N 11-173-01.

Both set-up and maintenance are a breeze if you’re a little bit of a handyman or woman. And once it’s been set up – note that it can be mounted vertically or horizontally, you should be able to enjoy it and use it for anything “water” for a long time. Why? Well, like any Shurflo pump, this one is one of the durable kind.

If you’re annoyed easily by noise(s), I’m not sure if you should get this version here. Something like our first product above that is known for its quiet operation would probably be best in that case. On the other hand, even for the pumps that are not the quietest in the world, don’t expect them to be as loud as a fighter jet. Nah, it won’t be that bad. You’ll just be able to clearly hear the pump in action. Doesn’t bother me. But maybe bothers you. The good news is that there are many different models on the market – including quieter ones.

Here’s a video that shows the complete pump replacement – very helpful:

– Conclusion

This user-friendly and durable Shurflo pump sits between our 3.0 GPM top pick and our 4.0 GPM model. It has 3.5 gallons per minute which should be sufficient for you. A tough spot to be in.

Its other main features and pros are that it prevents a reverse water flow and that it is easy to install and maintain.

It is not the cheapest model in terms of $s but still reasonably priced and it is not the quietest. The latter is no biggie if you ask me but if you need your pump to be as quiet as can be, then you may want to pick a model like the Flojet 03526-144A which has “only” 2.9 GPM though.

I would get this one here if for some reason you need something a little bit more powerful (in terms of GPM) than our top pick right above this review and if you’re OK with potentially paying a little bit more for that. If that’s the case, you won’t be disappointed by this candidate here.

Good flow rate: 4.0 GPM

Doesn’t need more than 10A

Can use more than one faucet

Higher Amp draw may require upgrades to your circuits

This Shurflo pump by Pentair has the highest throughput of all reviewed on this page: 4.0 gallons per minute (GPM). It makes quite a difference if you compare it to our second model above, for example, the Shurflo 4008-101-E65 , which has 3.0 GPM. We’re talking a 33% higher flow rate. Not bad. Crossing the 4.0 GPM mark means that you can run more than one water source in parallel without having to witness your water system struggle under the load.

Both products, the 4008 and the 4048 are very similar otherwise – except for the flow rate and the fact that the 4048 comes equipped with a bigger engine. Sure, the latter costs more but that is justified given it has more “horsepower”.

The 4048 pump here weighs 5.35 pounds and its dimensions are 14.7 x 8.3 x 7.7 inches.

Here’s that fancy term again: This is a positive displacement 3 chamber diaphragm pump. Don’t worry. That just describes the type of pump or the design of the pump.

With 10A, it needs more power than the smaller motors but given what it brings to the table, that’s really good actually. You’ll need a power circuit that has a 15 Amp fuse. In case you’re replacing your current RV pump, here’s a task for you I’d love you to accomplish before you buy this one here: Please check if your wiring can handle the larger Amperage if your previous pump had less than 10A. If so, you’re good to go. If not, you may either have to get a “smaller” pump or upgrade your wiring. The former sounds like the easier solution but maybe you’re talented when it comes to RV projects and replacing your wiring is no big deal for you. Good for you if that’s the case. The manual can help you out there with additional information.

This pump has the famous 1-way operation check valve to prevent a reverse water flow. That’s an important safety net.

And also this one – like its predecessor above – is a 12V DC (aka battery-operated) thermally protected, permanent magnet motor named P/N 11-173-01.

Pentair, by the way, has been around forever – since 1968. This is literally “forever”.

No way to adjust the speed for this one, sorry. But again, that really is no big deal. At least to me. Hopefully, it’s the same for you.

It is reasonably priced, has a decent 4.0 gallons per minute flow and the pump shut-off pressure is 55 PSI. The 4.0 GPM are just fine if you don’t put too much strain on your RV’s freshwater plumbing system. Meaning, if you don’t have the family consume water out of your RV’s faucets including the shower and toilet at the very same time, you’ll be fine. The shut-off pressure switch is there to stop the thing if the water pressure it reaches is getting too high – this prevents your pipes from bursting. A good feature. Once it switches off, it will go back to 40 PSI when it’s back on. This back and forth can create what we refer to as “pulsing”. This phenomenon – in case it bothers you too much – can be addressed with an accumulator. See below for details on what that is.

Operating quietly and thermally protected, this reliable, self-priming Shurflo Revolution water pump with internal bypass valve / cycling doesn’t need more than 10A. The former, the bypass valve, is here to manage some of that pulsing and cycling one typically experiences with 12 Volt water pumps. Thanks to this, the water pump is able to run and keep its pressure without cycling all the time. By the way, 65 PSI is the pressure that has that bypass valve all the way open. You can change the pressure switch and bypass valve settings if you wanted to. And the latter, the 10A, means – since this is not a whole lot of Amperage – that it is very likely that you can replace your current RV water pump without even having to adjust your electrical system / power source; that is something that sometimes comes with a new water pump. Probably not needed here. Very good. But you should obviously confirm this by checking your current specs.

It makes sure to pressurize the freshwater system in your camper whenever you don’t have the luxury of being connected to a convenient city water source. The pump (4-chamber diaphragm pump design) can run dry (primes up to 6 vertical feet from the tank) and it also contains a check valve that is built-in.

While it would be good if it slowed down when you don’t need the full force it can provide, this is no big deal really as it has no negative impact on anything really.

On the other hand, the pump surprises with really helpful features such as the thermal overload protector which shuts the pump down if it’s getting too hot. Only when it cooled down enough, it will turn back on automatically.

In terms of in and out ports, we have 1/2-inch 14 NPSM male threads.

And finally, more good news, the pump includes a mesh inlet strainer.

The user-friendly  Shurflo 4048153E75 is the bigger sibling of the  Shurflo 4008-101-E65 which is our best overall 12V RV pump.

Easy to install and maintain, it comes with a good flow rate of 4.0 gallons per minute (GPM) which is definitely sufficient.

This self-priming Shurflo pump is still reasonably priced if you account for its larger engine and throughput and has a check valve built-in.

A Shurflo diaphragm pump that works seamlessly for a lot of RVs and doesn’t need more than 10A is really an asset that you can’t go wrong with.

This is the sister or brother of the most – if not the most – popular RV fresh water pumps on the market.

Sure, it’s not necessarily the quietest Shurflo water pump or water pump per se and it’s not a variable speed RV water pump either. Also, you may have to upgrade the wiring in your camper if the 10A are a bit too much for it. But those are not cons that would make me advise against a purchase. The pros really outweigh those minor flaws.

This is your pick if you want the best overall 12V RV water pump but basically with a higher gallons per minute rating. This also implies that you’re able to spend a little bit more than all the other pumps on this page would cost.

This may now seem like a difficult decision. Which RV water pump is best for you?

It’s easy. Really. You’ll see.

Let’s go back to the conclusions for each of the products above.

• If you want to get a very good lower priced RV water pump where the throughput (in gallons per minute) doesn’t really matter because you won’t be traveling with a big party and your water consumption is below or close to average, the Flojet 03526-144A water pump here is a wonderful choice for you. This is the entry-level or lower end option.
• The Shurflo 4008-101-E65 should be your pick if you want the best overall 12V RV water pump and if you’re able to spend a little bit more than the lowest priced pump on this page would cost. This is my top pick among all 4 best pumps on the market reviewed on this page.
• I would order the Shurflo 2088-554-144 if for some reason you need something a little bit more powerful (in terms of its gallons per minute throughput) than our top pick right above and if you’re OK with potentially paying a little bit more for that. If that’s the case, you won’t be disappointed by this candidate here.
• The Shurflo 4048153E75 is the one that should land in your shopping cart if you want the best overall 12V RV water pump but basically with a higher gallons per minute rating. This also implies that you’re able to spend a little bit more than all the other pumps on this page would cost. This model here and the Shurflo 4008-101-E65 above are very, very similar.

You see, it’s really not that hard. Thanks to the fact that I narrowed your choices down to the 4 best pumps that you can get on the market, you’ll just need to answer a few questions for yourself and you’re ready to roll and order.

12 Volt RV Water Pump Guide

Below guide will help if you’re facing the decision which RV water pump to get for your camper. It provides some helpful additional information on RV water pumps, things to look for and accessories.

Considerations & Information

If you’re replacing your existing 12V water pump for whatever reason with a similar replacement model, congrats. It shouldn’t be too hard. Old one out, new one in, done.

Or you’re upgrading from your current model to a better, more powerful, more beautiful, etc. one.

In both cases, the main thing to look for is any potential issues with your electrical wiring as your new pump may draw more Amperes and therefore may need new wiring if the old wiring was for a lower Ampere number. I added a section for this below.

Another question is if your camper has more than one on and off switch for its freshwater water pump. In this case, you most likely have a pump controller in your RV and you’ll have to make sure your controller works with the pump you want to install. More on that below.

Your RV water pump makes sure that you have a reliable source of fresh water when you’re not connected to a city water supply. It allows you to use your faucets, your toilet, your shower, etc. whenever you’re boondocking, for example.

Usually, it only runs when it’s needed to pump water through your plumbing system. As soon as you flip the switch and it turns on, it pressures the pipes in your camper to a certain level – and that level is indicated in PSI (pounds per square inch). PSI is a very common measure of pressure.

Most 12V water pumps have a fixed pressure setting around 30 PSI but some allow you to adjust the pressure as needed.

By opening your faucet(s), etc., water runs through the system and the pressure measured by the water pump decreases. Since the pump has a target pressure it has been “told” to maintain, it will keep pumping in an effort to reach that target pressure. Therefore, it will keep running until it has reached the target pressure again.

There are two approaches for how water pumps shut off or stop their operation when you’re done consuming water and / or using them.

An ideal pump is smart enough to know when it reached its target water pressure and then shuts off. It also knows when you open the faucet and when it needs to take action to reach the pressure level again.

Not so smart pumps – or older models – require you to tell them when to work and when to take a break. You turn them on when you need them and you need to turn them off when you don’t need them. After that, you need to turn your faucet off.  In the case of such simpler pumps, you have to make sure you really turn them off and don’t forget as, otherwise, they’d keep running and ultimately overheat and potentially break.

I don’t think that there is any question why you need a 12V water pump. If you have an RV, it’s very unlikely that it came without a pump. But let’s look at the benefits of having one real quick:

If you’re not connected to your regular 30A or 50A power outlet at a campsite or wherever you may be camping out in the woods and you still want water that’s in your freshwater tank to come out of your faucet(s), then you’ll need a 12 Volt RV water pump. The pump transports the water from the tank to where you need it (RV kitchen, RV shower, RV toilet, etc.). That’s the first thing – they allow you to get your water whenever you need it and if you get or have a good one, they can even provide you with a consistent and smooth water flow without too many fluctuations.

The major types of RV freshwater pumps we differentiate are 12 Volt (12V) and 24 Volt (24V) pumps.

The only real difference is that the 24V ones have a larger and more powerful motor or engine compared to the 12V ones. And as a result, the 24V pumps can produce a higher water pressure and gallons per minute (GPM) throughput.

For your average RV, you’ll be just fine with a 12V pump and I really recommend getting one of those.

The 24V pumps are not in scope for this article. Maybe for a future one. Just leave a comment if you’re interested in those as well and I’m happy to tackle that topic for you.

The 12 Volt water pump gets its power from your RV’s batteries which provide 12-Vold (DC) power. This means that even when you’re connected to a power outlet at your campsite, the water pump in your camper will only be powered by 12 Volts. The same holds true for any other 12V devices in your RV – like a car radio, etc. What happens is that there is a converter in your electrical wiring / system that takes the incoming 120 Volts (AC) and converts them to 12 Volts (DC) that your water pump can handle.

Before replacing your RV water pump and installing your new one, please check what Amperage your RV’s wiring was designed for. If the Amperage for the pump is higher than what the wiring is specified for, you may need to upgrade your wiring first. Or, if you want to keep the existing wiring in that case, you can get a water pump with a lower Amperage rating.

If the Amperage of the product you picked as your (new) pump you want to order is lower than the one your power supply wiring says it’s been designed for, then you’re good to go.

Please refer to the manual of your RV pump to see what wire size you need for it. This is very important. I added a few links to manuals above and you can do some online research if you can’t find the right one or if you need some more information.

In case your camper has not only one but more than one on and off switch for your pump, it is very likely you have an Intellitec water pump controller. If so, it’s important to confirm your controller can handle the Amperage of the 12 Volt water pump you’d like to get. I added a few more details in the next section below.

Per above comment, in case your camper has not only one but more than one on and off switch for your pump, it is very likely you have an Intellitec water pump controller. If so, it’s important to confirm your controller can handle the Amperage of the 12 Volt water pump you’d like to get.

There are 10A and 15A Intellitec pump controllers available and you can see which one you have by taking a look at it. Look for it if you think you know where it is or consult the manual of your camper to see if it explains where they installed it in your camper. Worst case is you need to do some online research or even contact the manufacturer of your camper to find it. Once you found it: The Amperage should be written on it and, if not, check for any item or model number so you can go online to look up the Amperage of the controller you have.

By the way, the same goes for finding a potential second pump switch. They are usually located on the monitor panel that shows the status or level of your holding tanks but if it’s not there, you should double-check your RV’s manual or, worst case, do some online research or even contact the manufacturer of your camper to find it.

Some technical background for you:

In case you have such a controller, it means that you have a situation where the power for your pump doesn’t go through every single pump on and off switch in your camper. This saves wiring and reduces the complexity of the same. The controller basically rounds out the ground circuit to provide the pump with energy as soon as one of your pump switches is turned to ‘On’. The controller, which is located on the ground leg of the pump circuit, then opens up the ground circuit as soon as soon one of your pump switches is turned to ‘Off’ – this removes the power supply to the pump.

If you don’t have more than one on/off switch for your water pump, you don’t have a controller. That’s really easy to determine then. If you don’t have a controller, what’s happening from an electrical perspective is that the pump circuit goes through that one switch.

If your controller should ever break and you need to replace it or if you added a second on/off switch to your pump’s wiring, you can get a new  Intellitec 10 Amp Monoplex Water Pump Control here and I recommend doing some online research for the 15A version.

Here’s a summary of the most important aspects to consider when you’re looking for a camper water pump to buy. I’m not implying that having xyz feature or characteristic is important and a must. It’s up to you to weigh all aspects and come to a conclusion what’s a must have, nice to have or no-go for your water pump. I hope my reviews above help you with this.

Of course, you don’t want to get an RV pump that’s difficult to operate and stuff. So it’s good to keep an eye open to see if there are any negative reviews online for the pump you’re looking at. The good news: The pumps reviewed and recommended on this page are all easy to use.

Easy installation

Most RV freshwater pumps are relatively easy to install. Sure, if the thought of hooking it up to your electrical wiring and your RV’s plumbing concerns you a bit, then it’s best to have a professional do this for you. But overall, I’d say that with a healthy dose of curiosity, it’s not a big deal to do it yourself.

Ease of maintenance

Most 12V RV pumps are easy to maintain and if you go with one of the models on this page here, it’s very, very unlikely that you will have any problems anyway. There’s not much to do to maintain a water pump except for maybe cleaning the filter every now and then to get any debris and other particles out that have been collected there.

Product quality and durability

I’d read online reviews to see if there are any negative comments about product quality. The products reviewed here are all top notch and in general, a 12 Volt water pump for campers lasts for a long time. I’ve been a camper for years and never had to replace one because it broke. Sure, that’s not necessarily representative and a reflection of the whole population of RV campers but it gives you an idea. Also, replacing water pumps I’d say is probably one of the not so common topics you’ll find yourself discussing with other fellow campers.

Gallons per Minute (GPM)

This is an important number for RV pumps. It tells you how much gallons of water per minute  – abbreviated GPM – a pump is able to transport and spit out where you need it. Which is most likely a faucet, a shower or a toilet. It’s difficult to say what the perfect number for you is but in general, I’d say that you can get the lowest GPM model with 2.9 GPM above if you’re not going camping with a bigger family and don’t tend to use multiple faucets, the toilet and shower at the same time. The next model with 3.0 GPM should be fine for most aka average families that are fine with coordinating their water consumption. And if you know you’re gonna use your water a lot, different people will “operate” your faucets, toilets and shower in a rather “demanding” way, then it’s best to go with the 3.5 or 4.0 models above. But don’t expect a huuuuge difference between those different GPM values. There is a difference but it’s not day and night.

At the end of the day, the goal is to get a pump that is not too strong and delivers more than you need drawing more power than needed. And also to get a pump that is not too weak for your purposes.

Also, check your RV’s manual or contact the manufacturer to see if there are any details on (maximum) allowed flow rate.

There you go. As I said, this is a little bit of a tough one right there.

Water Pressure

In the reviews above, you probably noticed that I talked about the shut-off pressure of the water pumps and the water pressure they have when the bypass valve is all the way open. The water pressure is indicated in PSI or pounds per square inch. There’s not more you have to know about this other than that your RV’s plumbing is designed for a certain maximum water pressure. It’s best to check your RV’s manual or contact the manufacturer to see if there are any details on (maximum) allowed water pressure. If you exceed the allowed maximum, you risk bursting your water pipes. But having said that, all the pumps reviewed and recommended on this page use a water pressure that is normal and something that your average RV is able to handle without any issues. But like I said, still good to check.

Amperage / Energy Consumption

The Amperage tells you how much power the pump will consume and therefore draw from your RV’s 12 battery or batteries. Unless your RV’s battery is hopelessly overwhelmed already or close to it, operating a water pump shouldn’t put too much burden on it. But if you’re unsure or want to do all your homework diligently, you can check upfront if your desired water pump is expected to cause problems or not. One aspect where the Amperage is important is your RV’s electrical wiring. See section “12 Volt RV Water Pumps and Electrical Wiring” a few paragraphs above in this guide section down here for details.

There’s not much to say here as this page here focuses on your typical 12 Volt water pump for your average campers. That’s all we need. But please note that there are larger vehicles (the super duper mega motorhomes maybe, buses, etc.) that use 24V, etc. pumps. Just saying. Don’t worry about it. Not in scope for this article. Maybe for a future one. Just leave a comment if you’re interested in those as well and I’m happy to tackle that topic for you.

It would be beyond the scope of this article and a reasonable level of detail to explain what a self-priming pump is. This website here has a very good explanation that you can check out if you want to. This is purely optional though. All you need to know when you go shopping and read about my product recommendations above is that a self-priming water pump is a good thing.

Check-valve

If a check-valve is built into a water pump or not is an important question. The job of a check-valve is to hold back the water from your city water connection (if connected to one at a campsite) so that it doesn’t flow into and fill up your freshwater tank – we don’t need that mess.

Auto switch

This is the smart vs. simple pump topic from a few paragraphs above:

Not so smart pumps – or older models – require you to tell them when to work and when to take a break. You turn them on when you need them and you need to turn them off when you don’t need them. After that, you need to turn your faucet off.  In the case of such simpler pumps, you have to make sure you really turn them off and don’t forget as, otherwise, they’d keep running and ultimately overheat and potentially break.

This is a nice feature that shuts off the valve when it’s been running (hard) for a while and, while doing so, heated itself up to above a certain threshold. This extends the lifespan of the pump and prevents it from breaking.

Most RV pumps can be heard. There’s pumping, slurping and all other sorts of noises going on while a pump is running. As explained above, there are ways to make a pump a little bit quieter but I’m not sure if it’s worth it. That’s something you’ll have to decide. In general, if you’re easily annoyed or distracted by sounds and noises, make sure to get a pump that calls out its quiet operation like the first model reviewed on this page. Otherwise, the noise level generated by those pumps is pretty much very similar and nothing I’d consider as too concerning. It’s not super loud, ya know?

Adjustable / Variable Speed

There are pumps on the market with a variable speed feature. Your typical RV water pump, however, doesn’t need to have this fancy feature. There’s no need for that, really, as the pumps on this page do a fine job as is. They run at a constant speed and for the purposes of providing the campers in an RV with freshwater, that is just fine.

You may want to measure your new pump to make sure it’ll fit in where your current pump is located or where your old pump sat. Most of them have standard sizes but it’s always good to double-check.

As with any purchase decision you’ll ever make, the price plays a role. And water pumps are no exception. Different brands and models come with different features, etc. which impacts the price. I recommend reading above product reviews including the all-up summary to better understand what you’ll get for your money and how to decide what is right for you.

While I’m always trying to keep costs to a reasonable level, there are a couple of add-on items that I recommend ordering – the strainer below being one of them.

Strainers ( Twist-On , Swivel Nut )

Strainers are miraculous little helpers that help keep anything out of your water pump that could cause unnecessary repairs: debris, other small particles, etc. If such objects make it into your RV pump, they can damage the pump’s diaphragm which will have its toll on it and probably break it prematurely. This is an accessory you should really get ideally.

Regarding those strainers, you just have to decide if you want to get one with NPSM threads (fixed fittings on both ends) or one with both NPSM and NPT threads (fixed fitting for the inlet, swivel nut fitting for the outlet). Both models have a transparent design so you can actually see when it’s time to clean the mesh filter (50 mesh stainless steel screen). For cleaning, the strainers can be disassembled and reassembled easily. And don’t fear the installation – you just add it t your water system – the threads make this very easy.

If you’re a proud owner of the Shurflo 4048153E75 water pump, you don’t need to order a separate strainer as there’s one included with this product already.

Pump Silencing Kit

This is an optional accessory you can get if the “pulsing” and other sounds your water pump makes bother you a lot. I usually don’t even hear those sounds as I really don’t pay much attention to it. But everyone’s different and if you want to eliminate some of the sounds emanating from your RV water pump, this kit is a good choice for you.

The  SHURFLO 94-591-01 Pump Silencing Kit   – specifically designed to work with Shurflo pumps and to reduce noise and vibration in all plumbing systems – connects directly to the inlet and outlet ports of the pump and has two 30″ hoses with 1/2″s female swivel fittings as well as two 1/2″ x 1/2″ NPT-Male pipe nipples.

The Shurflo RV water pump silencing kit has two flexible hoses that fit between the water pump and your RV’s plumbing lines.

Accumulator

Like I said in the intro on top of this article (it’s all the way up in case you want to read it (again)), the pumps I picked are the best solutions for most campers but they run at a constant speed. So if you want to turn your pump into a more elegant one that doesn’t need to cycle all the time (except for when you have your water running full steam ahead), then you can get an accumulator. My position here is similar to the silencing kit above. I wouldn’t need it as I’m not annoyed by the pumping, cycling, pulsing or whatever we wanna call it. But if you are, this Accumulator is a good way to address this.

It is pre-pressurized to 30 PSI with a built-in diaphragm and the way it works is that it reduces pump cycling and it smoothens your water faucet pulses by basically providing an additional little tank on the outlet side of your pump (aka the pressure side). This little tank fills with water which is then used by your water pump. Makes sense, right? As a result of this “reservoir”, your water pump doesn’t have to cycle as hard as it would if there was no such additional water available. Again, a nice to have. And a nice one indeed. Just check the manual of your RV pump to confirm such an accumulator works for your water pump.

Let’s see what you should keep in mind when installing and running a 12 Volt RV water pump.

• I just mentioned it there. Those are water pumps. For water. So please don’t consider using them to pump anything else like gasoline for whatever reason. Duh, I know, why would you. You won’t believe it but I heard stories about folks (ab)using their water pumps for other liquids.
• When you received your pump and before installing or using it, I recommend reading the manual that came with it. Some things may seem self-explanatory and so you may be tempted to just go ahead and install it but I’d really advise against this and encourage you to read the manual first. One of the things it will help you understand, for example, is if you’ll need to upgrade your wiring or if the one that’s in place in your camper will work for your new 12V water pump.
• When you install the pump, please make sure it can breathe. What I mean by that is that it should be installed in a ventilated area where the air can circulate. The reason for this is that these pumps warm up while they’re doing their job and so they need to be able to breathe a bit. That’s also the reason why you shouldn’t and don’t need to put any insulation material around them. They’ll be fine. 🙂 Also, before I forget it, please don’t install them in an area where there are flammable gases as the engine of the pump can create sparks that would or could set the gas on fire.
• After you’re done with the installation (good job!), you may want to check if there are any water leaks. Check the pump itself and any plumbing fittings there. It’s also good if you can come back on a regular basis after the initial installation to ensure there are no leaks. It’s best if you can make this check part of your standard inspection that you do every x days or weeks or so to ensure your camper has no issues and everything is running smoothly and looking good.

Installing a (new) RV water pump is not rocket science. Sure, there’s a certain curiosity and game plan you need to bring to the table but other than that, there’s not a whole lot of magic going on there.

The only challenge is usually placing the pump as you’ll need to really flex your body in order to reach the far corners of the universe where the pump goes. Bring a towel or two and also make sure to read and follow the instructions in the manual of your pump; it’s good to also check the manual of your RV and current pump for any clues and details. And if the good old books don’t help or don’t exist anymore, you can do some online research or even call the manufacturer(s) of both your camper and your pump. For example, what wiring do you have in your camper and what wiring does the new pump require? Do you need to upgrade your wiring as the new pump draws more power? It’s those type of questions that only proper research can answer and that will prevent you from potentially making costly mistakes.

It’s important to switch off the battery power switch for the water pump before you start your project as this will remove your pump from the power system in your camper and open your faucets so the water system can depressurize.

Here’s a good video that shows the installation of an RV water pump:

As always, I hope my product reviews and guide were helpful and enabled you to get the best 12 Volt RV water pump for your purposes.

I’m sure each and every one of the 4 models reviewed above would work fine for you. The selection process leading up to your purchase decision just comes down to a few small details that you need to answer for yourself and then you’re good to go and order.

I wish you many happy and “hydrated” hours, days, weeks, months, years and decades of camping with a well-working 12V RV water pump.

However, if you’re also interested in a pump with great value, the affordable Flojet 03526 Triplex operates smoothly and delivers good bang for your buck.

What to Consider When Buying 12V RV Water Pumps

Having a working water pump can be the difference between a miserable, spartan RV holiday you’d rather wipe from your memory, and a dream road trip you never want to forget.

An onboard water pump makes it possible to shower, fill the sink, flush the toilet, and carry out many other tasks you take for granted at home. It’s very likely that your RV will have an existing water pump and, with a little luck, you’ll never have to give it a second thought. But if you’re looking to upgrade your water pump, or desperately need to replace a faulty one, there are some things you need to know. Keep reading as our buying guide has you covered.

Types of 12V RV Water Pumps

Constant speed pump.

As the name suggests, a constant speed pump delivers water through your system at a single rate of flow. It’s either on or off and it’s not possible to adjust the water speed. Constant speed pumps are the most common type of 12V RV water pumps because they’re the simplest and most affordable option. 

Variable Speed Pump

Variable speed pumps deliver water in a manner you’re probably more accustomed to, in that the flow rate varies depending on what is required. The built-in pressure switch adjusts the speed of the motor in order to maintain a constant water pressure, which results in a varied flow rate. Variable speed pumps are usually quieter than constant speed pumps, but can also be more expensive.

High Volume Pump

The least common type of 12V RV water pump is the high volume variety. They move water at a much faster rate than a standard pump, but this means they also require more power. For that reason, they’re usually only found on the biggest RVs and motorhomes, which can provide the necessary 50 amps. Any water pump listed as having a flow rate of 4 gallons per minute (GPM) or more is considered a high volume pump.

12V RV Water Pump Key Features

When it comes to voltage, you’ll find that water pumps are usually 12V, 110V, or 120V. Regardless of the size of your RV, you’ll want a 12V water pump as the other voltages are for actual houses and are way too powerful even for the biggest rigs.

Now that we’ve narrowed it down to 12-volt water pumps, there are still a number of things to take into consideration before getting your wallet out. These considerations depend on the size, make, and model of your RV. If you can’t get your hands on the original owner’s manual, you should be able to find the information you need with a quick Google search.

Water Pressure

The most important factor to consider when choosing a new water pump is the RV’s maximum water pressure. This is important for performance and safety reasons, although most pumps will be in the “safe” range of between 60 and 75 pounds per square inch (PSI).

If you’ve spent any time inside an RV, you’ll know that nothing is any bigger than it needs to be and every square inch of the layout has been designed for maximum efficiency. The same goes for all the bits you don’t see, which is why it’s important to measure the space in which your current pump is installed. Chances are, there’s not going to be much additional room for you to fit anything bigger.

Water speed—or flow rate—is measured in gallons per minute (GPM). Your owner’s handbook will confirm what the optimal water flow rate is for your particular make and model of camper. This is important because the higher the GPM, the harder the pump has to work. More powerful water pumps tend to be bigger and draw more electrical power, too. Many pumps are now available with adjustable speeds to combat this issue.

12V RV Water Pump Benefits

Use multiple faucets simultaneously.

With one of the best 12V RV water pumps, you’ll be able to use your RV’s plumbing and associated appliances without ever worrying. As your pump pulls water from the source, it’ll use its motor to deliver that water to multiple faucets. You can easily turn on a sink and take a shower, using multiple faucets at the same time without worrying about what’s happening in your hoses and pipes. 

Control Water Pressure

One of the biggest advantages of a 12V RV water pump is the ability to achieve better water pressure. While a water pressure regulator is handy here, your pump helps move water effectively and efficiently, which means it plays a crucial role in your water pressure and overall flow power. If you want a low-pressure or high-pressure flow, there’s a water pump that can deliver (and it can make every shower a whole lot better!).

Low Power Draw

While RV water pumps can vary in their power usage, most 12-volt pumps are specifically made to suit campers of various sizes. This means they’re generally light on amps, ensuring they don’t overwhelm your RV’s power system. Typically, 12-volt RV water pumps help conserve power so they can easily run in the background each time you open up faucets for different needs, meaning you should never even notice their impact on your electrical system.

12V RV Water Pump Pricing 

A 12-volt RV water pump will cost you anywhere from $60 to $80 on average. This price range includes pumps that offer various flow rates and can handle different maximum amounts of pressure. If you’d like a premium pump (or one with more power), you can expect to spend anywhere from $150 to $250. However, these pumps do tend to be larger and may not be a fit for all RV models.

Tips and Tricks

As with something you do for decades upon decades, you pick up a few tips and tricks along the way in terms of selecting the right product, and/or using it. That’s the case with us and 12V RV water pumps. To help you bridge the information gap, here’s a selection of what we’ve learned along the way.

• Most 12-volt RV water pumps are small and compact, designed to fit into tight spaces, but you should always check your owner’s manual to determine which specs are the right measurement for your pump.
• If you opt for a water pump that’s too small, you may not get a leak-free fit. 
• To prevent leaks regardless of the size of the pump you’re using, look for products that offer a leak-free seal. With rubber and a tight-fitting seal around the connection point, a pump with a leak-free seal offers more security.

You’ve got questions. The Drive has answers!

Q: How strong is a 12V RV water pump?

A: RV water pumps do vary in their strength and their maximum PSI, but on average a pump can function safely at anywhere from 60 to 75 PSI.

Q: Can I run my RV water pump when connected to a city water line?

A: Often, city water lines are quite high in pressure—so high, in fact, that the pressure level can damage your RV’s plumbing components. You’ll want to make sure you’re using a regulator if you need to connect to a city water line, so you can bring down the PSI. While pumps can often handle higher water pressure, it’s better to err on the side of safety so you aren’t replacing burst hoses.

Q: Should I opt for a bigger 12V RV water pump for my RV?

A: While bigger is often better, especially when it comes to power and capability, that isn’t always best for every RV. First of all, certain RVs require smaller water pumps simply because they don’t have the space for larger ones. Secondly, smaller RVs really don’t need the same gallons-per-minute rate since the plumbing systems are smaller and not as far-reaching. Check with your RV’s owner manual to determine what size and flow rate is best for your specific camper.

Glamping in an RV can completely change a person's experience of the great outdoors. RVs provide plenty of creature comforts that you just can't get with a traditional tent setup, not the least of which is running water. While most RVs have water tanks, you'll likely have to do a bit more accessorizing if you want to heat that water up enough to do something like shower. An RV tankless water heater can do exactly that. There are plenty of options out there, so we've wrangled up some of the most popular and accessible heaters in this list below.

What is an RV tankless water heater?

An RV tankless water heater is just like it sounds. Rather than heating water in a tank, tankless water heaters heat the water instantly as it's moving through the system so no tank is needed. In theory, this system can offer an unlimited supply of hot water (or, at least, it can heat as much water as you have available in your RV).

Why do you need a tankless water heater?

While it's certainly not a necessity to have a hot water heater for an RV, it can definitely make your trips a lot more pleasant. Sure, it's possible to shower with cold water, but it's certainly not fun. As for what makes a tankless water heater more desirable than a traditional heater, the big benefit is that they're often smaller than traditional heaters, which is extremely helpful in a space as compact as an RV. Also, as mentioned above, they heat water instantly rather than requiring the user to wait for a tank of water to heat up.

How does a tankless water heater work?

Water is heated on its way through the pipes of the heater, rather than in a large tank like a traditional water heater.

How do you use a tankless water heater?

First, you'll need to get it installed. How do you install a tankless water heater? Well, unfortunately it can vary depending on the heater. If you're uncomfortable doing this yourself, we recommend speaking to a mechanic familiar with tankless water heating systems.

Pros and cons of using a tankless water heater?

Of course the biggest pro of using a tankless water heater is that you'll have hot water on your excursions! Going the tankless route ensures an "unlimited" and instant supply. However, tankless water heaters can be expensive and a pain to install, so you'll have to weigh the convenience against your budget and your comfort level with moderate-lift DIY projects. 

How much is a tankless water heater?

As you can probably tell from our selections, you'll be able to find water heaters available in a wide range of price options. In general, you can probably find one anywhere from $100 for a budget option to $1,200+ for something a bit more high-end.
