Water Pumps for RVs

Water is essential for life, and crucial for your RV to function. If you intend to go off-grid, then filling up your RV reserves is not going to be enough to deliver water to all your water-based appliances.

For that, you are going to need an RV water pump. Many RVs come with a water pump already installed but you may have specific water pressure needs that it doesn’t meet. 

In this guide, we take you through what features to look out for in water pumps for RV living so you can find the best one suited for you.

If you are looking for a new pump or wanting to replace an existing water pump, read on to find out which model won our best RV water pump on the market title as well as the competitors it beat.

Our Guide to Travel Trailer Water Pumps

If you’re reading this guide, chances are you already know what an RV water pump is and are here for some guidance on buying the right one. However, if this is your maiden voyage into the world of RV water pumps we’ll start with a quick description.

Best RV Tankless Water Heater Banner

An RV water pump is a device that pumps water from the RV’s reserve to the faucets, toilets, and showers in the RV. It also stabilizes the pressure.

It’s that simple. Without it, you’ll have no running water anywhere in your RV unless you connect up to city water (discussed in the next section).

How an RV Water Pump Operates

Water pumps, sometimes called diaphragm pumps, work by motorized suction. The diaphragm has a valve on either end and when one valve closes, the other opens, and suctioning begins. Once full of liquid, the valve at the other end closes while the previously closed valve opens. Water then rushes from the area of high pressure to the areas of low pressure (i.e., your faucet).

Using City Water

As briefly stated above, if you’re connected to a city supply, then you don’t need to use the pump in your recreational vehicle. The city water system is designed to provide adequate pressure. It is unlikely you will always be in the vicinity of city water however and if so will still need an RV water pump.

When using city water, make sure to connect a regulator to the hose before connecting it to your recreational vehicle. Sometimes city water pressure can be too high, which can cause damage to water lines in your RV. If this does happen, when you switch back to your RV water pump, your system may not work correctly.

A great benefit of using city water on newer RVs is that you can fill your fresh water tank simply by switching a valve inside the tank. This way, when you’re done using the city water connection, your tank is full, and you can switch back over to using the RV pump with ease.

Powering the Pump

A water pump is an electrical device, so they need to be hooked up to a power source. RV water pumps are DC-powered so can run from your 12V battery. If you come across a product that isn’t a 12-volt water pump, look the other way because it’s not for RVs.

It’s easy to set up a camper water pump. You don’t have to be a professional electrician, and you don’t need any specialized tools. A socket wrench, a flat-head screwdriver, and a pair of wire cutters would be all you need.

Key Features to Consider

Types of Water Pumps

There are several different types out there, but the most commonly used for RVs are diaphragm pumps. Knowing the pros and cons of diaphragm pumps will prepare you for how to use and maintain them.

Pros & Cons of Diaphragm Pumps


  • Inexpensive
  • Large displacement volume
  • Versatility in drive options
  • Most are self-priming
  • Easy installation


  • Can cause water to pulsate
  • Needs a high PSI of air to operate powerfully

You can also choose between a constant speed pump, a variable speed pump, or a high-volume pump. Constant speed pumps will only pump water at one pressure value. Variable speed pumps are adjustable and allow the pressure to go higher or lower as you see with your faucet at home. Finally, a high-volume pump allows a higher-than-average speed with a higher pressure.

Pounds Per Square Inch (PSI)

PSI is a measurement of the force of liquid flowing through your plumbing. Most RV plumbing systems are designed to withstand 40 to 60 PSI. Anything outside of this pressure range could damage your RV plumbing system.

Gallons Per Minute

The flow rating shows how many gallons of water the pump can process in a given minute and is an indicator of how strong a pump is. Lower-end products will have a rating of fewer than two gallons per minute, while high-volume pumps will have a rating of four or more. Anything in between is considered average/standard.

If you expect to use multiple faucets simultaneously, then the amount of water you need at any given moment will be higher. Thus you’ll need to opt for an RV water pump that has a higher flow rate to ensure your faucets have an adequate water supply.

Amperage (Amps)

RV water pumps tend to use a low number of amps, usually under ten. If you happen to have a high-volume water pump, it may use up to 15 amps. Keep in mind that your motorhome will have a maximum rating of either 30 amps or 50 amps, and you may have other electronics running as well. Aim for low amps, so you don’t have to worry about maxing out.

Other Factors to Consider

Size and Ease of Installation

RV water pumps are small, but some are more compact than others. Water pumps are not a one-size-fits-all product so get your measuring tape out to make sure you get a size that will fit into your designated pump space.

The installation process is something else to keep in mind. Consider where you’ll be installing it, how easy it is to get to this spot, and all the tools you’ll need. Since it is DC-powered, you’ll want to make sure that the leads on the pump are long enough to connect to the power source.


RV pumps are designed with a built-in pressure switch that automatically shuts off once the water pressure reaches the set PSI limit. This prevents damage to your RV’s plumbing system. This same feature will automatically kick back on once the pressure has dropped low enough. 

To do this the auto shut-off feature has a check valve that keeps the pressure from randomly kicking in and out, as well as keeping liquid flowing in one direction. 

There is also an accumulator tank that assists by reducing the likelihood of pressure spikes, which can cause the auto shut-off feature to kick in.


A new RV water pump, or one that’s been out of operation too long, will need to be primed (filled with water and flushed through the system) before it’s ready for use. Most models are self-priming, but check to make sure.

Design and Noise Level

The majority of RV water pumps are designed the same way. There is an opening on each side of the unit, one for a hose/pipe leading to the freshwater tank, and the other for a hose/pipe to your faucets. As for noise level, water pumps pulsate, which can make noise. That said, the better the product is made, the less it will pulsate but the best bet is to check the decibel level for the model.


Having a warranty is excellent insurance in case your unit malfunctions. Usually, a good warranty lasts for several years, but any warranty is better than none.

Best RV Water Pump Reviews

ShurFlo 3.0 GPM Revolution #4008-101-A65


RecPro RV Water Pump Direct Replacement For Shurflo 4008-101-A65 3.0 GPM | 12V Water Pump | Self-Prime | Camper Water Pump | RV Plumbing

The ShurFlo Revolution is a four-chamber diaphragm pump, with a respectable 3 GPM flow rate and shutoff pressure of 55 PSI. What sets it apart is the unique one-piece diaphragm design. This makes it easier to service and maintain since you’ll have fewer moving parts.

The ShurFlo is self-priming up to six feet and can run dry without damage. It weighs about 4 pounds and measures 8.1 x 4.9 x 4.3 inches. It has an internal bypass valve and needs a maximum of 7.5 amps to run. Best of all, it comes with a two-year warranty.

The only issue we had is the amount of vibration it made, it’s a fairly noisy water pump. If you plan to keep it away from your main living areas, it may not bother you too much.

Bottom-Line: The ShurFlo Revolution water pump is a high-performing, durable option and at an affordable price.

SeaFlo 33 Series

Best with Variable Speed

SEAFLO Water Diaphragm Self Priming Pump 3.0 Gallons/min (10.6 Lpm) 45 PSINew Rv/Marine 12 Volt Dc / 12 V Demand Fresh

The SeaFlo 33 Series is a popular choice balancing a decent flow rate and pressure with an affordable price. It has a rather standard flow rate of up to 3 GPM, yet it is the pressure range that sets it apart from other models.

This model has a variable speed motor and features an adjustable automatic pressure switch that can be adjusted from 17 PSI to 60 PSI. It’s easy to install and maintain and has rubberized feet to help with noise reduction from vibrations. This model is self-priming up to six feet and can run dry with no damage.

If we could request one change from the manufacturer, it would be to make it a four-chamber pump instead of just three. Having more chambers increases the final pressure output, and it could be challenging to get up to 60 PSI with only three chambers.

  • PROs

    • Adjustable pressure
    • Rubber feet for noise reduction
    • Santoprene diaphragm
  • CONs

    • Only three chambers.
    • Designed with pipe threads instead of hose threads.

Bottom-Line: This is the closest you’ll get in your RV to have the versatility of a home faucet.

Bayite 1.2 GPM

Best Budget

bayite 12V DC Water Transfer Pump with 2 Hose Clamps 12 Volt Diaphragm Pump Self Priming Sprayer Pump with Pressure Switch 4.5 L/Min 1.2 GPM 80 PSI Adjustable for Weed ATV Marine Boat

If you only have one or two appliances in your RV to supply this budget option will do the job whilst saving you money. The Bayite is a bare-bones deal, but what it does, it does well. 

It flows at a rate of 1.2 gallons per minute yet has an impressive 80-100 PSI rating, adjustable with the pressure adjustment screw on the top of the unit. That means that if your one appliance is a shower, you’ll have sufficient pressure to make it count.

This model weighs a mere 1.3 pounds and measures 8 x 3 x 4 inches. It’s lightweight and compact, which contributes to the low flow rate and makes it easy to install and handle. 

The only gripe we have with this product is that many people complained of a faulty automatic shut-off valve. This could lead to leaking.

  • PROs

    • Extremely affordable
    • Low current draw of 5 amps
    • High PSI
    • Adjustable pressure
  • CONs

    • Auto shut-off valve is unreliable
    • Short warranty (1 year)

Bottom-Line: You get what you pay for, but the Bayite is impressive with such a high PSI at such a low price point.

At 4 pounds and 10.5 x 5.6 x 5.3 inches, the Progear 3200 is a bit on the large side as compared to some others on this list. However, this added size and weight help the unit to be more efficient and are also an indicator that good, high-quality parts, which usually weigh more than cheap parts, have been used.

  • PROs

    • Made in the U.S.A.
    • No rapid cycling
    • Whisper-quiet technology
  • CONs

    • Expensive compared to others

Remco (55-AQUAJET ARV Aquajet RV Series Water Pump

The PowerRV Aquajet is the Dyson of water pumps. Every feature of this model goes above and beyond the competition.

Firstly, this product is capable of producing a flow rate of 5.3 gallons per minute at 65 PSI. It does this with its impressive five-chamber design with five valves to match and you can automatically control motor speed. 

For those that prefer to buy American then the Aquajet is a good option with whopping self-priming of up to 13 feet, quiet operation, and ability to run dry without damage. The PowerRV Aquajet measures 12.3 x 6.2 x 5.4 inches and weighs 6.4 pounds.

None of the other models on our list come close to the specs and quality that the PowerRV Aquajet boasts. Evidently, this comes at a cost, and the price tag for this one is far higher than for any other product on this list.

  • PROs

    • Made in the U.S.A.
    • Self-priming up to 13 feet
    • Variable speed
    • Super quiet operation

Arterra PDSI-130-1240E

Most Steady Flow

Arterra PDSI-130-1240E RV Fresh Water Pump with Power Drive Technology

The Arterra is a great pump with the best steady water flow we saw. Diaphragm pumps “pulsate,” which can sometimes cause winks, which are skips in the water flow. The Arterra is made with an exclusive Power Drive Technology which gives this model one of the steadiest water flows seen in an RV pump.

Other than this, the rest of the Arterras specs are in the solid mid-range. It’s capable of up to 40 PSI and 3.0 gallons per minute. It has a fairly standard self-priming of 6 feet and uses a maximum of 7 amps. And also has middle-of-the-road measurements at 9.2 x 5.5 x 5.5 inches and weighing about 4.5 pounds. 

This pump works very well and, if you’re the type that likes every little detail to be perfect, you’ll enjoy the steady stream of water that the Arterra provides.

  • PROs

    • Power Drive technology
    • Thermal protection from overloading
    • Four-chamber design
  • CONs

    • Noisy

Bottom-Line: This pump is an excellent all-rounder for any RVer, but it’s especially good for people who desire a steady consistent flow.

Flojet #03526-144A

Most Compact Option

Flojet 03526-144A Triplex Diaphragm Automatic Water System Pump, 2.9 GPM 50 PSI, 12 volt DC

Water pumps for RVs are generally small and lightweight. However, if you need something really small and portable, the Flojet has you covered. 

At only 9 x 4 x 4 inches and weighing only 2.6 pounds it’s great for tight spaces and moving around. However, don’t let size fool you, it’s a powerful unit that produces impressive results.

The Flojet is capable of 2.9 gallons per minute at 55 PSI. It’s self-priming up to nine feet and can dry-run without damage. 

This model is designed well and even has protective covers for the hose attachments. Despite its compact size, this pump delivers big results.

  • PROs

    • Ignition protection
    • Noise absorbing mounts
    • Snap-in port fittings
  • CONs

    • Outer casing isn’t as durable as other models
    • Not good for really hot water

Bottom-Line: If you need a compact water pump, the Flojet fills this need while still getting the job done effectively.

Amarine Made 12v Diaphragm

Lowest Amp Draw

Amarine Made 12v Water Pressure Diaphragm Pump Self Priming Pump 4.3 L/min 1.1 GPM 35 PSI RV Water Pump for Caravan Boat Marine Agricultural

When we came across the Amarine Made pump we were skeptical of its specs due to its low price point. However, if you respect the limitations this model has, you’ll see that it does what it says and very well. 

Things to keep in mind about this unit: With a flow rate of 1.1 gallons per minute at 35 PSI this model is designed to handle a low workload and so is not suitable for big campers. It’s only going to provide ample water for one or two appliances at a time, and if you choose your shower as one, it’s not going to have as much pressure as a premium model would. 

Out of all the RV water pump models we reviewed the Amarine Made had the lowest amp draw at 2.7 amps. This product is ideal for the 30-amp RVer who is right at their power limit. 

It measures 7.5 x 4.2 x 2.6 inches, so it’s compact, and it’s easy to install. It’s also extremely lightweight, coming in at only 1.5 pounds, the lightest we came across.

  • PROs

    • Extremely low amp draw
    • Close to silent operation
    • Extremely easy installation
  • CONs

    • Outer casing isn’t as high-quality as others
    • A little noisy

Bottom-Line: If you have an extremely tight budget or barely have amps to spare, the Amarine Made is a perfect fit.
