Best RV Water Pump: Don’t Let Your Pressure Drop

Water is essential for life, and it's also crucial for your RV to function. However, if you intend to go off-grid, then just filling up your RV reserves with water is not going to make all the water-based appliances work.

You need an RV water pump.

Of course, many RVs already come with the water pump, but there will come a time when you need to replace it. We've reviewed a number of water pumps to find the best one out there.

This article will give you the results of what we found as well as our suggestion for the best RV water pumps.

Guide to Travel Trailer Water Pumps

If you’re reading this guide, the chances are that you already know what an RV water pump is and need some guidance on buying the right one. However, it’s a big possibility that you don’t know and that’s quite alright. Just in case you don’t, 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 water reserve to the faucets, toilets, and showers in the RV. It also stabilizes the water pressure.

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

How an RV Water Pump Operates

Water pumps, sometimes also called diaphragm pumps, work by motorized suction. The diaphragm has a valve on either end. 1 valve closes, and the other opens as the suctioning begins. Once full of water, the valve at the other end closes while the previously closed valve opens. Water rushes from the area of low pressure to the areas of high pressure (i.e., your faucet).

Using City Water

As we briefly stated above, if you’re connected to a city water supply, then you don’t need to use the water pump in your recreational vehicle. The city water system is designed to provide adequate water pressure. This doesn’t mean that you don’t need an RV water pump. You may not always be in an area with access to city water.

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

A great benefit of using city water is that, on newer RVs, you could fill your freshwater tank 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 your water pump with ease.

Powering the Water Pump

A water pump is an electrical device, so it makes sense that it’s going to need to be hooked up to a power source. RV water pumps are DC-powered, so they can run from your 12V battery. There are air pumps that are powered in other ways such as air, 115-120V AC-powered, and more, but you wouldn’t need any of these. In short, 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 hook up an RV 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 in a Camper Water Pump

Types of Water Pumps

There are several different types of water pumps, but the good news is that most RV water pumps are diaphragm pumps. Knowing the pros and cons of diaphragm pumps can prepare you for usage and maintenance.

Pros & Cons of Diaphragm Pumps

Pros:

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

Cons:

  • 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. The continuous speed pump only pumps water at one pressure value. The variable speed pump allows the water pressure to go higher or lower like your home faucet. 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 the water flowing through your plumbing. Most RV plumbing systems are designed to withstand 40 to 60 PSI. Anything outside of this water pressure range could damage your RV’s plumbing system.

Gallons Per Minute

The flow rating is how much water the pump can process in a given minute and is an indicator of how strong a water pump is. Lower end products will have a rating of less 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)

Most RV water pumps use a low number of amps, usually under ten. If you happen to have a high-volume water pump, these may use up to 15 amps. Remember that your motorhome either has a maximum of 30 amps or 50 amps, and you 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. Make sure you get a size that will fit into your designated water pump space, which means you need to pull out the measuring tape.

Ease of installation is something else you’ll want to look for. Consider where you’ll be installing the water pump, how easy it is to get to this spot, and all the tools you’ll need to install it. Since it is DC-powered, you’ll want to make sure that the leads on the water pump are long enough to connect to the power source.

Auto-Switch

RV pumps are designed with an automatic shut-off feature 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 in once the pressure has dropped low. The parts of the RV water pump that make this feature work are:

Check Valve

A check valve keeps the pressure from randomly kicking in and out, and keeps the water flowing in one direction.

Accumulator Tank

This reduces pressure spikes, which can cause the auto shut-off feature to kick in.

Self-Priming

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

Design and Noise Level

Most RV water pumps are designed the same way. You have the water pump and an opening on each side. One is for a hose/pipe to the freshwater tank. The other is a hose/pipe to your faucets. As for noise level, water pumps pulsate, which can make noise. The better the product is made, the less it will pulsate. Check the decibel-level for the model.

Warranty

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

Best RV Water Pump Reviews

Shurflo Revolution RV Water Pump by Pentair Model #4008-101-A65

Best RV Water Pump for Water Pressure

The Shurflo Revolution is a four-chamber diaphragm pump and has the highest PSI of all the water pumps in our list. It has a shutoff pressure of 55 PSI, a flow rate of 3 GPM, and features an internal bypass. Best of all, it only needs a maximum of 6.6 amps. This makes it great for larger campers or campers that will have a high-water usage.

The Shurflo is self-priming up to six feet, which is the average. It can run dry without damage. 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 weighs about 4 pounds and measures about 6 x 6 x 4 inches.

The only issue we came across with this product is that it gives off a bit of a loud vibration. If your Shurflo will be away from your main living areas, it may not bother you too much.

Bottom-Line: This is a high-performing, durable product at an affordable price range.

SeaFlo 33 Series Water Diaphragm Self-Priming Pump

Best RV Water Pump with Variable Speed

Water Diaphragm Self Priming Pump 3.0 Gallons/min (11.3 Lpm) 45 PSI New Rv/Marine 12 Volt Dc / 12 V Demand Fresh

The SeaFlo 33 Series is popular because you get what you need at a good, median price range. It can produce a water flow of up to 3 GPM. While it seems like your average unit, the PSI is what sets it apart from others.

The SeaFlo 33 Series features an adjustable automatic pressure switch (meaning that it’s a variable speed pump) that can be adjusted from 17 PSI to 60 PSI. It’s easy to install and maintain, and it even has rubberized feet to help reduce the noise from vibration. The 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 to having the versatility of a home faucet.

Bayite RV Potable Water Pump

Best RV Water Pump on a Budget

bayite 12V DC Fresh Water 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 RV Camper Marine Boat Lawn

If you only need to supply water to one or two appliances in your RV, you can save money by getting this budget option. 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 but has an impressive 80-100 PSI rating. That means that if your one appliance is a shower, you’ll have sufficient pressure to make it count.

The model weighs a mere 1.3 pounds and measures 6.5 x 3.9 x 2.4 inches. It’s lightweight and compact, which contributes to the low flow rate. However, it’s 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.
    • High PSI.
    • Adjustable pressure.
  • CONs

    • Auto shut-off valve is reliable.
    • 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.

Best American-Made Water Pump 12v

USA Adventure Gear Progear 3200 RV Replacement Water Pump | 4008 Revolution Direct Replacement | 3 GPM | Electric Whisper Quiet Operation | Self-Priming | Approved for Potable Water Use

The Progear 3200 is a great, high-quality product that is an excellent investment due to its durability. It’s self-priming up to six feet and as a flow of 3.0 gallons of water per minute. The model can provide pressure up to 50 PSI, and will have no problem powering several appliances at once.

At 4.75 pounds and 12.5 x 6.2 x 5.3 inches, the Progear 3200 is a bit on the large side compared to other products on the list. However, this added size and weight help the unit to be more efficient, so it’s not necessarily a bad thing. This is also an indicator of good, high-quality parts, which usually weigh more than cheap parts.

  • PROs

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

    • Expensive compared to others.

The Flow Max is extremely quiet, so it’s good if vibrating noises disturb you. It’s made with noise-canceling rubber feet to absorb vibrations.

Like most RV water pumps, it can run dry without damage. It’s self-priming up to six feet, and it comes with a screen filter to keep debris out of the water. The pump measures 10.5 x 6 x 6.5 inches and weighs around 4.5 pounds. It has a slightly high max amps rating of 9.5, so you’ll have to make sure you have enough amps to support it.

  • PROs

    • Heavy-duty motor.
    • Very quiet.
    • Simple installation.
  • CONs

    • High max amps.
    • Five minutes on time, 10 minutes off.

Artis Products RV Pump

Most Steady Water Flow

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

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

The Artis water pump’s other specs are what you’d expect from an RV water pump. It’s capable of up to 40 PSI and 3.0 gallons of water per minute. The product measures 9.2 x 5.5 x 5.5 inches and weighs about 4.5 pounds. It uses a max of 7 amps. The 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 Artis provides.

  • PROs

Flojet RV Water Pump Model #03526-144A

Best 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, the Flojet has you covered. It’s only 9 x 4 x 4 inches and weighs only 2.6 pounds. It’s great for tight spaces and portability. However, don’t let the size fool you. Despite its size, it’s a powerful unit that produces impressive results.

The Flojet is capable of 55 PSI and 2.9 gallons of water per minute. It’s self-priming up to nine feet and can dry-run without damage. The water pump is designed well and even has protective covers for the hose attachments. This compact model 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.

Amarine Made Diaphragm RV 12 volts Water Pump

Lowest Amp Draw

Amarine Made 12v Water Pressure Diaphragm Pump 4.3 L/min 1.1 GPM 35 PSI - Caravan/rv/Boat/Marine

When we came across this water pump, we were skeptical because of the lower than low price and the low flow rate and PSI specs. However, if you respect the limitations this model has, you’ll see that it does what it does very well. It’s also extremely lightweight, coming in at only 1.5 pounds. You won’t find another water pump any lighter than this.

Things to keep in mind about this unit: It’s not suitable for big campers. It’s only going to provide ample water for one or two appliances at the time, and if you choose your shower as one, it’s not going to have as much pressure as a premium model would. None of these are negatives because this model is designed to handle a low workload.

The pump is capable of 1.1 gallons of water per minute and 35 PSI. Where the pump shines is that it has one of them lowest amp draws of all the models we reviewed. It only uses a max of 2.7 amps. This product is for the 30-amp RVer who is right at their limit. It measures 6.7 x 3.9 x 2.6 inches, so it’s compact, and it’s easy to install.

  • 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 will be a great fit.
