  • Flow rate: 4.5 GPM
  • PSI: 45

With a flow rate of 4.5 gallons per minute, this Eco-Worthy RV pump has the highest volume water supply on our guide.

In addition to that, the pump will turn on automatically when you open the tap and switch off when you close the faucet.

If you look closely, you will notice it’s fitted with rubber-mounted feet to tone down the noise and vibrations. But perhaps the biggest trick under its sleeve is the filter that helps to remove impurities before supplying the water.

For a pump that delivers 4.5 gallons per minute, it’s no surprise that it consumes more power than an average 12V RV pump. Even so, it would be useful especially for multi-purpose applications.

What We Like

  • Multi-purpose water pump
  • Self-priming pump
  • High flow rate
  • Automated pump cycle
  • It’s quiet
  • Easy to install

What is an RV Water Pump, and Why Would You Need It?

An RV water pump is used to force water from the vehicle’s built-in tank to the piping system. Basically, if you want a consistent flow of water from your rig’s tank to the shower, toilet, or sink, you will need an RV water pump.

However, an RV water pump doesn’t just force water through the piping system, but it can also regulate the water pressure.

That means you can reduce the pressure to consume less water per minute and increase the pressure to get things done faster.

Besides that, you don’t need to rely on city water and campground systems if you have an RV water pump.

How Do They Work?

An RV water pump is usually designed with two ports; an inlet and an outlet. Once the RV pump is up and running, the diaphragm expands to draw in the water from the RV’s storage tank to the inlet port.

As the water flows through the pump, the diaphragm contracts to force the water through the outlet or discharge line at a higher pressure.

The pressurized water is then distributed to the piping system which is connected to your shower, sink faucet, and toilet.

What to Look for When Buying an RV Water Pump

Gallon Per Minute (GPM)

For starters, you need to consider how many gallons of water the RV pump you want to purchase can deliver in one minute. Most RV pumps on the market typically discharge a flow rate of 1 GPM to 4 GPM.

Of course, an RV pump with a high GPM (gallon per minute) will supply a consistent flow of water to more faucets simultaneously. However, there is a catch; the higher the GPM, the more power you will need to operate the pump.

Then again, if your RV pump delivers a low GPM, you could have problems running multiple faucets at the same time. For that reason, you should avoid an RV water pump with a gallon per minute rating of 1.2 and below.

As a matter of fact, the best RV water pumps on the market can supply 3 or 4 gallons per minute; anything more than that and you risk draining your battery too fast. Better yet, you should choose an RV water pump that you can easily adjust the GPM speed.

Pounds per Square Inch (PSI)

Unlike the GPM that measures the flow rate, the PSI (pounds per square inch) is all about the water pressure. How much do you need? Most RV piping systems are designed to handle between 40 and 70 PSI, so make sure you choose a water pump within that scale.

Keep in mind that if you use a water pump with a higher PSI than your plumbing system can handle, you could damage it. On the other hand, if you choose a water pump with less than 40 PSI, don’t be surprised if the water pressure is underwhelming.

However, just to be on the safe side, you should check the RV’s manual to figure out how much PSI you need on a water pump.


Most RV water pumps you will find on the market are either 12 volt or 24-volt units. 12-volt water pumps are usually the standard in most RV and motorhomes because they consume less power.

But if you think you’ll need more water pressure, you could choose a 24-volt pump; although it will require more maintenance than a 12-volt water pump. Not to mention, a 24-volt water pump will increase your water and electrical bill.

Let’s just put it this way; if you’re on the fence about it, we recommend you pick a 12 voltage RV pump rather than getting something that will consume too much power than necessary.


The size of the water pump is a big deal considering that it needs to fit in your designated RV space. But first, you need to figure out what size of water pump you should get by measuring the space where you want to install it.

Depending on your RV model, you can have different spaces to install the water pump and it could be anywhere from the water basement storage area, under the bathroom sink, under the bed, or near the water heater.

The good news is; a standard 12-volt water pump has a compact design that can fit in most RV rigs.

Noise Level

You don’t want to get distracted every time your RV water pump is running in the background, do you? For the sake of your tranquility, you should consider buying an RV water pump that comes with noise dampening material and a low vibration mount.

Interestingly, some RV water pumps are designed with a 5 chamber diaphragm to reduce the noise as much as possible. Alternatively, you can minimize the noise and vibrations during installation by sliding a padded foam under the pump before you mount it.

Self-Priming and Thermal Protection

Since the RV’s storage tank has a limited water source, you should choose a pump that can deliver water from the tube; especially if the supply is almost depleted.

Besides that, the self-priming feature helps to prevent the pump from damage in case the water runs out.

What else? The best RV water pumps have a thermal protection feature to prevent a fire breakout. In other words, if the pump overheats, it will shut down automatically.

Types of Water Pumps

Constant Speed

A constant speed RV pump supplies water at a single speed or flow rate. That means, you can’t adjust the water flow rate or speed but you can switch it on or off.

Even though constant speed water pumps are simple and affordable, they have a shorter lifespan compared to other types of water pumps. This is because constant speed pumps can continue running longer than necessary.

Variable Speed

As the name suggests, variable speed pumps automatically adjust the water flow rate to match the demand. However, the water pressure is usually constant even if the flow rate is variable.

The good thing about variable speed pumps is that they don’t make a lot of noise. Also, if you find a variable speed pump with an automated cycle, it will reduce your energy consumption.

On the flip side, variable speed pumps are more expensive than constant speed pumps.  

High Volume

Most high-volume water pumps supply more than 4 gallons per minute. Of course, due to such a high flow rate, you would need a big rig that can provide 50 amps.

Otherwise, most high-volume water pumps are rated at 24 volts, and they’re usually installed in buses, trailers, and trucks. For the average RV dweller, it doesn’t make sense to install a high-volume water pump in a typical RV unless you consume water like an elephant. 


If we had to pick the overall best RV water pump, we would choose Remco 55 Aquajet RV Series Water Pump. This is because it’s an automatic variable speed pump with thermal and low voltage protection.

However, if you’re on a tight budget, we recommend the Camplux 12V Water Pump

  1. I bought a Bayite pump to replace a ‘d’ battery pack/shower pump for an instant hot water camping shower. The feet are all rubber which was good for me as the mounting holes on my sprayer were not the exact same footprint. This allows for some wiggle room if it’s not the exact dimensions.

  2. I used other pumps in my off-grid cabin that were all broken after no time and were very loud. The Flojet 03526-144A water pump is literally one of the best finds I have ever come upon. It is quiet, but most importantly, it is very reliable. I have had it for 3 years and could not be happier. What I like about it is that it makes use of an automatic triplex diaphragm, which allows it to operate in a smooth manner without the need for an accumulator tank. It is because it already comes with a pulsation eliminator.
