See, this model only has a 1.1 GPM and a 35 PSI rating, which you might be thinking is a little too low on both accounts. However, this pump has proven to still provide excellent water flow given the praise it received in the customer reviews.

For instance, its equipped with a variable speed motor that gets rid of the on/off cycling that often haunts more standard RV water pumps.

This variable speed motor also offers the customer the ability to detect drops in water pressure with its pressure sensors. If a drop is detected, these pressure sensors will automatically adjust and continue to provide high-quality, consistent water flow.

You might think this speed motor means that the noise operation level will be higher than your typical water pump? Well, don’t because this motor doesn’t spin too fast and will only increase its speed when the demand for water increases.

RV Water Pump Buyer’s Guide


Buying an RV water pump isn’t the simple process you might envision it being. There are essential factors you’ll need to discuss before you find the best choice. And this section will dive deeply into these factors as a way to ensure you’re prepared for this buying experience.

Things to know before buying an RV water pump

Choosing the top-rated water pump for RV will come down to understanding certain factors that determine whether or not a model’s high-quality. And in this section, we’ll discuss these essential factors to ensure you pick the perfect product for your situation.

Noise Operation Level

Some RV water pumps can get a little noisy. Given you probably want your RV as peaceful as possible, I’d recommend avoiding these particular models at all costs. Instead, your goal should be finding a quiet product that keeps a low noise operation level even with multiple faucets open.

For instance, an RV water pump with a 5-chamber design should be able to keep the noise level down regardless of the number of faucets open. Another trick is checking the pump’s mounting type because some can absorb sound.

Another simple way to ensure you get a product that keeps their operation noise low is by reading the customer reviews. If the water pump you’re considering has a noise issue, these reviews will undoubtedly make it abundantly clear.


An RV water pump’s GPM (gallons per minute) rating refers to the gallons of water per minute the pump will supply your RV. The models on the market will typical offer you anywhere from 1 GPM to 4 GPM.

An RV water pump’s GPM (gallons per minute) rating refers to the gallons of water per minute the pump will supply your RV. The models on the market will typically offer you anywhere from 1 GPM to 4 GPM.

This range is an excellent barometer to stick with during your search. Anything less than 1 GPM will be too weak to offer high-quality performance. But a model with a higher than 4 GPM rating will be too powerful for your RV.

It’ll also end up costing you more on both your electric and water bills. As a result, you’ll want to find a model that hovers between the range mentioned above.


Like we discussed above, RV water pumps generally come into two types: 12-volt and 24-volt RV water pumps. It’s essential you understand, which one is a better fit for your particular rig’s circumstances.

In most cases, I’m going to recommend sticking with the 12-volt models as these are the standard design for RVs. They’ll make sure the job gets done and won’t provide so much pressure that it causes issues with your pipes.

But if you’re looking for extra pressure, the 24-volt options are at least worth considering. These devices do provide a more reliable and powerful performance; therefore, could be useful for larger rigs like a fifth wheel trailer.

These 24-volt devices do have a drawback though; they’re going to run your electric and water bills higher than your standard 12-volt would as they use more power. It’s something you’ll want to think about before making your final decision on which voltage you need.

With all this in mind, it becomes apparent that figuring out which voltage fits your particular situation better is an essential piece to this rather complicated puzzle.


The PSI or pounds per square inch is another factor that becomes vastly important in this decision-making process. It’s essential the water pump you buy has a PSI rating that mimics the recommended one by your rig’s manufacturer.

This rating is usually between 60 and 75 PSI, which is considered the safe zone when it comes to water pressure. However, it won’t hurt to ensure the water pump you’re buying meshes well with your RV; therefore, take a gander at your RV’s manual.

It should give you a recommended PSI for the water coming into your RV. Use this number to wisely pick an RV water pump that can provide the rating given in the manual.

Ease of Installation

Any RV water pump worth considering will be a product that’s easy to install. In fact, it should be one that allows you to do the whole installation process yourself. I’d recommend looking for a small, compact model as these units tend to have fewer parts.

And as anyone knows; fewer parts means easier installation. It also ensures the process won’t be taxing for you physically as the lack of parts makes this products lightweight. But do make sure the smaller pump has the same measurements as the one you’re trying to replace.

We don’t want you to buy a product that doesn’t fit into your designated water pump spot after all. It also in your best interest to ensure the model comes with all the needed supplies for the installations: Teflon tape, water hose, screwdriver, etc.

What are the different types of RV water pumps?

In the RV world, water pumps typically come in two types, 12-volt RV water pumps and 24-volt RV water pumps. As you might expect, there are certain situations where one might be more effective than the other, and we’re going to discuss these scenarios in detail below.

12 Volt Water Pumps

The more common of the two types, the 12-volt water pump is the standard operating design for most RVs. If you’re looking for a standard model for a lighter job, a 12-volt water pump is the right move for you.

These devices are specifically designed for RVs and should be your purchase unless you have a situation where you need a lot more pressure. These water pumps will keep both your water and electric bills in check and get the job done efficiently.

24 Volt Water Pumps

After my explanation of the 12-volt water pumps, you’re probably asking yourself why I would want a 24-volt water pump? Well, sometimes you’ll need a little extra pressure and these devices will provide that for you.

In fact, using a 24-volt water pump will guarantee a reliable and high flow performance that a 12-volt version might not be capable of producing. However, these models will cause spikes in both your water and electric bill as they need more power to run effectively.

As a result, we recommend going with the 12-volt water pump unless your situation really calls for the need of a water pump that provides more pressure. After all, 24-volt water pumps are going to cost more as well; therefore, you don’t want to spend extra money on something you don’t actually need.

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

In most cases, the right pump to go will be a 12-volt model as they’re the standard water pump design for most RVs. The 24-volt ones are more reserved for trucks or buses, which is why you should only consider these models when you’re in need of a little extra pressure.

But even in these situations, the extra pressure these 24-volt models can offer end up doing more harm than good. Therefore, I’d recommend always sticking with the 12-volt water pumps; they’re safer, more logical, and less expensive,

How to install an RV water pump?

The process of installing your new RV water pump will ultimately come down to the one you end up buying. After all, these things can vary model to model. But the standard operating procedure will look something like the steps I demonstrate below:

Step 1: Empty Your Water Tank

Flush out everything from your RV’s water tank by connecting a water hose to the tank’s base. This action will empty all the water from the tank. At this point, if you want, you can save the water by directing the hose to a drum or another large water holding container.

From there, disconnect the link from the tank to the old RV water pump, which will cause some water to leak out.

Step 2: Disconnect the Old Water Pump

You’ll first want to disconnect your RV’s battery. From there, use a screwdriver and remove the wires that are connected to your old pump. In most cases, these wires will be red and black. It’s also imperative that you disconnect the hoses connected to the pump as well.

After removing the hoses and wires, move onto the bolts and screws that hold the old pump in place. Once everything is removed, carefully disconnect the old pump.

Step 3: Put the New Pump into Place

Take in the new pump and position it where you just took out the old one. Use your screwdriver to secure it and bolt it down. It’s essential you make sure the pump is bolted down tightly. After bolting down the pump, take out some Teflon tape and wrap up the pipe threads.

With the pipe threads wrapped, you should move onto connecting the inlet hose and outlet house, which both need to secure with clamps.

Step 4: Reconnect the Wiring, Battery, and Water Tank

First, reconnect the water tank’s link to the pump: ensure this connection is fastened tightly. After effectively reconnecting the water tank, move onto the electrical wiring. And lastly, reconnect the RVs battery, which will give your new RV water pump a live power source.

Step 5: Test the System

Now, it’s time to test the system. You do this by starting your RV and evaluating whether or not your new pump goes on standby. The pump should emit a sound, which confirms that it’s turned on and working: this sound might be different from pump to pump.

If the pump doesn’t make a sound, it’s probably an indicator something’s wrong with your electrical connections. As a result, you should check them and make sure they’re correctly connected. You should also check the battery to confirm that is suitably connected as well.

Step 6: Test the Pump

Once you confirm the pump is properly running, inspect all the lines and connection to ensure there aren’t any issues with leaks or holes. You should then fill the tank a quarter of the way full with water and turn on the pump.

Now, go to a faucet and turn it on to further confirm the water pump’s doing its job. It’s important you remain patient as it could take a couple of moments for the water to come out from your faucet.

If it does take a few moments, it’s because the pump is still filling the pipes up with before it comes out of your faucet.

Overall, this installation process doesn’t seem too complicated, right? And trust me; the install for the pump you choose won’t differ drastically much from the steps laid out above, but it’s still essential that you read instruction manual beforehand.

If you don’t read the instruction manual, you might end up missing a crucial step that’s pivotal to ensuring a high-quality performance from your water pump.

RV Water Pump FAQs

What is an RV water pump?

An RV water pump takes the water from the tank and puts up into your RV’s plumbing system. Its job is to increase the flow of the water and stabilize any pressure that might build up from its arrival inside your plumbing system.

On the average, an RV water pump will hold 50 to 200 gallons of fresh water depending on the model. It’s mostly the device that gives you access to the fresh water that runs through your RV.

In doing so, these products have two jobs: keeping the water pressurized and providing a certain amount of water per minute. As a result, it controls the output of the water of your RV’s showerheads, faucets, toilet, etc.

Without this essential piece of equipment, you’d have a hard time consuming the fresh water that lies inside your tank. In fact, it’d be downright impossible. I mean, imagine RVing without the ability to procure fresh water: sounds like absolute hell, doesn’t it?

Due to this, you can see why an RV water pump becomes a piece of equipment that needs to be a top-notch product.

How does it work?

The process of how an RV water pump works isn’t one that’s too complicated. The first thing you need to know is these water pumps work off your demand. Therefore, it’ll only turn on when you need it too.

Regarding the actual pumping process, it’s relatively simple. The pump works by pressurizing the pipes to predetermined pound per square inch setting also called PSI. This setting is often set around 30 PSI, but some models are more technologically advanced and have an adjustable PSI setting.

If you’re looking for a product that offers more control, these water pumps with the adjustable PSI setting could be the right move for you. It’ll give you more flexibility and offer the choice of setting the water pumping experience to your preferences.

Once you turn on the pump, it’ll start pumping water. It’ll continue to pump water until all the faucets, showerheads, and other water outlets are closed. After you turn it off, it’ll keep pumping a little while longer just up to the point it reaches the preset water pressure on the pipes.

With the newer models, the water pumps will stop working the moment it reaches the preset water pressure. As a result, the pressure on the pipes or lines will stay the same until you open a water outlet such as a faucet.

After you open a faucet, if the water pump notices a drop in the pressure, it’ll start working again to regain the preset water pressure. But sadly, older models don’t have the same method of operating that the new ones do.

These models work off manual operation. Sounds like a hassle, right? Well, it is as you have to turn the water pump on every time you need fresh water. The process for these devices we go like this: open faucet, turn the water pump on, and then you get your desired fresh water.

And then, you have to turn it back off and close the faucet. If you have an older manual model, make sure you follow this process to a tee. If you don’t, it could lead to some consequences that you don’t want a part of your relaxing RV life.

See, these older models, don’t have that snazzy automatic shutdown feature. As a result, they won’t stop pumping unless you turn them off even as it hits the preset water pressure setting.

This constant pumping could lead to overheating, which could ultimately cause your plumbing line to burst. Then, things like flooding become apart of your life, and that’s just not fun for anyone involved.

What is the quietest RV water pump on the market?

Many experts agree that Shurflo’s Ultra Quiet Motorhome Water Pump offers the lowest noise level. It seems to emit a whisper-quiet sound that everyone would be okay with. So anyone looking for a peaceful and effective replacement RV water pump should consider buying it.

If you’re wondering why it didn’t make our list, the price is a bit too expensive. I’d much rather choose a model like the Amarine-made 12v Water Pressure Diaphragm Pump. This RV water pump 12V model’s noise level is a little louder while being much less costly.

What size water pump do I need for my RV?

Choosing the correct size for your RV water pump upgrade isn’t too tricky. In most cases, RVers want to select a model with a 3 to 3.5 GPM production rate. Water pumps with these rates are commonly found on smaller or mid-sized motorhomes.

In fact, SHURFLO’s 2088-554-144 Fresh Water Pump would be an excellent choice. It provides outstanding performance without any issues. Meanwhile, it still offers a quiet noise level to ensure the device remains user-friendly.

However, 3 to 3.5 GPM motorhome water pumps might not be enough for some Class A RVs. Owners of these RVers would look for a larger model, often rated at five or more GPM.

One of my favorite options for these massive rigs is NPGLOBAL’s 12V Water Diaphragm Pressure Pump.

Can I put a bigger water pump in my RV?

RV owners can install a more extensive water pump in their motorhome if there’s enough room. So if you’re considering a bigger size, consider the space inside your rig. You don’t want to buy an RV camper water pump that doesn’t fit into the intended area.

After all, it’ll only lead to making room for it or buying a new water pump travel trailer model. It just seems like a massive waste of time. I once made this mistake and had to spend another $200 to fix my error.

So please, don’t be like me and check the specifications inside your camper manual. It should tell you everything about the proper pump size and flow rate. You can then estimate whether you have enough room for a larger 12V on demand water pump.

How much does a water pump for an RV cost?

Camper or trailer water pumps have a wide range of price tags. For example, I’ve found models available for only $50 while others cost almost $500. As a result, buyers will need to consider what they’re looking for in their fresh water RV pump.

For instance, someone who wants a bargain buy would be much better choosing a model close to the $50 range, like Bayite’s 12V DC Fresh Water Pump. It’ll provide acceptable performance while keeping our savings intact.

However, for higher performance quality and advanced features, an expensive variable speed RV water pump would be preferable. I’d recommend Remco’s RV Aquajet 5503-AV15-B636 ARV H2O Pump, as quiet RV water pumps don’t get much better than this one.

How long do RV water pumps last?

Most RV water pumps should last over a decade with proper care and maintenance. All the options mentioned in our article have proven to offer this longevity. But it does require users to be practical and keep up with repairs or other issues.

If you’re worried about maintenance, check out “How to repair an RV water pump leak?” It provides guides to ensure you can deal with cracks and leaks in your water pump. This info and your product’s manual should provide everything you need to know about proper water pump maintenance.

What are the most trusted RV water pump brands?

When buying products, customers are always searching for the best brands to lead them toward the highest-quality items. This experience doesn’t magically change when you’re searching for an RV water pump.

As a result, there are a couple of manufacturers that stand above the rest in this marketplace as well. These companies are the ones that are mentioned in our product review section, but even in that populace, there are three that further separate themselves from their competitors: Shurflo, Remco, and Seaflo.

And I thought telling you a little bit about each would give you an idea of why these three companies are ahead of the pack. It’ll hopefully convey to you that these manufacturers are the standard, which you should hold every other brand up to regardless of the product’s features or price.


As a company that’s been in the game since 1968, Shurflo needed to create a reputation among their customers as being high-quality. Which is something they’ve done effectively through making pumps that “provide reliable, smooth and quiet operation for many enjoyable years of use.”

With a company mission like this one, it’s not hard to see why Shurflo has been incredibly successful over the years.


Remco has been a leader in the pump making industry for a long time. And they don’t just produce high-quality water pumps, but all sorts of other fluid handling equipment “that excels in performance and reliability, and surpasses the end user’s expectations.”


With the following goal of “provid[ing] the highest quality products, at a competitive price, with unbeatable customer service“, Seaflo has become a manufacturing leader in Marine, RV, and Agricultural part marketplaces.

In doing so, they’ve cultivated a tremendous relationship between them and their customers. I mean, Seaflo has been a favorite among RV owners in a rather quick time with their willingness to go the extra mile for the customer’s satisfaction.

Overall, if you’re lucky enough to buy a water pump from one of these manufacturers, there’s no question you’re buying experience will be a positive one. In fact, any of the companies mentioned in our product review section will provide you with a positive and stress-free purchase.

Are RV water pumps loud? How to make them quiet?

Your RV’s noise level will ultimately depend on the model you end up buying. As a result, this factor becomes an incredibly important part of your search for a 12 volt water pump for RV. I mean, a loud water pump can make your RV life an absolute nightmare.

With this in mind, you should take a gander at the customer reviews. Trust me; if someone found the product you’re researching to be too loud, you’ll find a complaint about it there. But if you do find yourself with a noisy water pump, there are some things you can do about it.

See, there are these products called water pump silencers that should take care of the problem.

I’ve found this particular one to be a fantastic product, which will make sure your water pump never becomes a loud annoying nuisance.

How long should an RV water pump run?

As most of these RV pumps use an on-demand system to operate effectively, you can feel comfortable knowing that you can leave it on for as long as possible and it won’t cause any issue. However, if you’re connected to city water, this will cause some problems.

Your water pump could start pumping in unregulated city water. If you aren’t connected to city water, this issue isn’t a problem because the RV’s water will be pumped in from your RV’s onboard holding tank.

It’s also imperative to understand that these on-demand systems will only run after you use a water-using-device such as a toilet or a faucet. In other words, these high-quality pumps will not use power unless you make it known you need water by turning on a water outlet.

Therefore, if your RV water pump is continuously running, there’s a high probability that there’s some issue, which needs some fixing.

How to repair an RV water pump leak?

As mentioned in the previous part of this article, if your water pump is continuously running, there’s a strong chance that there’s an issue. In most cases, this problem is a leak, which can be a real nuisance and needs to be fixed immediately.

The first thing you’ll need to do is identify what the reason behind leaking is? Most commonly, the leaking comes from one of the two following culprits: a broken check valve or cracked water lines. And thankfully, fixing both of these issues is a rather simple process that I’ll demonstrate below:

Repairing a Broken Check Valve

Step 1: Pull the Valve Off the Hose

The first thing you’ll want to do turn off the water. You should then remove the old check valve from the hose that was connecting it to your RV’s freshwater tank. It shouldn’t be a complicated process as typical you can pull the valve off the hose by using your hands.

Step 2: Disconnect the Old Check Valve

You should be able to disconnect the check valve from the water pump by merely pulling with your hands.

Step 3: Install the New Check Valve

With the old check valve out, you should be able to fit the new one right into the hose or tube that connects the freshwater tank. The check valve’s directional arrow should be pointing toward the water pump.

Once you’ve fitted it in, connect the check valve’s opposite end to your water pump. Most of the time, the new check valve will slip right into place.

Repairing Cracks in the Water Lines

Step 1: Visually Inspect for Cracks

If you’ve examined the check valve and everything appears to be fine, you should operate under the impression that a crack in the water line is causing the leak. As a result, you should inspect all the lines going to and from the water pump for cracks.

Step 2: Place a Bucket Under the Cracked Water Line

Once you think you’ve found the cracked water line, you should place a bucket under the connection between that line and the water pump.

Step 3: Loosen the Connection Between the Water Line and Pump

If water starts pouring out, it means there isn’t a crack in the water line. On the other hand, if water does come out, it could be an indicator that there’s a crack. It’s essential that we note the lack of water coming out could also be a suction problem.

An issue regarding suction usually comes about from running a water pump with an empty water tank. If you’ve done this before, you can rule out a suction issue by filling the water line with water and attaching the pump.

Next, turn the pump on and let it run for several minutes, and test the water line again.

Step 4: Fix the Cracked Line

If you’ve established that a cracked line is indeed the problem, it’s time to repair it. The first thing you must do is turn off the water pump again. From there, take out a pocket knife and cut out the cracked part of the water line.

You then cut a piece of plastic tubing that has the measurements of the cracked part you removed. If you’re confused about which kind of tubing to get, you should consult with the nearest RV store.

Step 5: Patch up the Water Line

If you’re using tubing that has a lot of slack, it’s in your best interest to patch up the water line with one fitting. But if the tubing has no slack, you should use two and attach one to each end of the line.

With your fittings in place, place the plastic tubing in the spot between them. You should then secure it with PVC adhesive, which should ensure everything stays put. Leave it alone for 12 to 24 hours so that it can dry.

Once it’s dry, you can then turn the water pump back on and see what happens.

With these two step-by-step guides, you should have no problem returning your water pump to its former glory. However, if you find it’s neither of these two things, you should call in a professional to come and have a look at your water pump.

Even if you find it’s one of these two issues and don’t feel comfortable doing the fixes yourself, calling a professional would be your best bet. I mean, there’s a reason these people have those jobs after all.


Wading through all these available RV water pump options can be quite a frustrating experience. I mean, most of the time it seems like every product is offering all the same features and benefits.

But given all the information you now have at your disposal, this process should become much simpler and less stressful for you. Just remember, take your time and use this information as it should help make it clear, which model is the best RV water pump for you.

And once you do find the high-quality unit that’s perfect for your RV, you can comfortably relax knowing that your water pump will be a non-issue for years to come. It’ll let you get back to enjoying the things that matter most.
