Spending the weekend off-grid? Need to park up your RV somewhere without a water hookup? You’d better make sure your water pump is in good working order.
To ensure you get a steady flow of running water during your adventures, you may need to upgrade or replace your current model. However, with so many options on the market to choose from, deciding on the best RV water pump for your rig can be a headache,
To help you make the right choice with little hassle, we’ve reviewed the best RV water pumps that money can buy. We’ve also included a handy buying guide to answer all your pre-purchase questions.
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.

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.
Installation is relatively straightforward and this pump has the distinct advantage of being able to be mounted in any position – making it a good replacement for most setups, as well as being a direct replacement for the Shurflo 2088 pump. In addition, its built-in check valve ensures that you won’t get any backflow.
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.
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.

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.
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.
As most home plumbing is around 60 PSI, you may want to look at a pump capable of operating around this pressure provided your RV system is compatible.
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.
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.
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.
Alternatively, if you have a tiny camper and just one or two water points, then the compact, inexpensive Seaflo 21-Series will more than suffice. It has an extra-low power draw and the ultimate space-saving design so you can enjoy the convenience of running water no matter where the road takes you.
