Precitrade Shurflo

Precitrade Shurflo 2088-554-144 Fresh Water Pump, 12 Volts, 3.5 Gallons Per Minute, 45 Psi

Shurflo is a well-known name in the RV community with regard to water pumps. They’ve been around since the 1960s. This has given them the advantage to not only perfect their product but to expand and grow as RVing has.

The Precitrade Shurflo has a flow rate of 3.5 gallons per minute, which is pretty standard for an RV water pump.

It also has a check valve that prevents water from flowing into the pump when you’re hooked up to city water.

Because it is the same size as the water pumps in most RVs, replacement is relatively easy and, if you’re handy, can be done in under 30 minutes.

The Precitrade Shurflo is a nice little workhorse that quietly does its job in the background so you don’t have to think about it. There are even some Shurflo pumps that are still working after 20-25 years!


  • Easy to install
  • Quiet
  • Check valve prevents city water backflow


  • The pressure cut-off is pre-adjusted

Budget Option

Seaflo 42 Series

SEAFLO 42-Series Water Pressure Diaphragm Pump w/Variable Flow For Reduced Cycling - 12V, 3.0GPM, 55PSI

The Seaflo-42 series pump is a variable-flow RV water pump that delivers 3.0 gallons of water per minute.

This pump comes with all the hardware you need and is compatible with most RVs as a replacement unit.

Even though the Seaflo 42-series RV water pump is capable of running if your tank runs dry, we don’t recommend it!


  • Compatible with most RVs as a replacement
  • Can run dry without damage


  • Some reports of the pump not shutting off

Quietest Option

Lippert Components

Lippert Components Flow Max 12V RV Water Pump, 3.0 GPM, 50 PSI, 9.5 Max Amp, Self-Priming, Screen Filter Included - 689052

Have you ever tried to shower in the morning without waking up everyone else in your RV and just automatically turned on the pump switch – and the sound woke up everyone else in the RV?

You just might be able to avoid that situation with the Lippert Components RV water pump.

This pump delivers 3.0 gallons of water per minute, which is a little on the lower side but still plenty of pressure to enjoy that shower.

It comes with a screen to help keep debris out of your pump and help it last longer.

The real downside to this RV water pump is that the manufacturer suggests a duty cycle of five minutes on and then ten minutes off. This is great for a quick shower but not so much other times.

Another benefit of purchasing the Lippert is that, if you ever need it, they have excellent customer service representatives. You’ll probably appreciate that feature more than anything if you ever need to call.

At a pricepoint that’s just a little more than our budget option, this RV water pump delivers decent pressure quietly and at a great price.


  • Quiet
  • Lower price point
  • Great customer service


  • Five minutes on/10 minutes off duty cycle

Best for Running Multiple Fixtures

Remco 55 Aquajet

Remco (55-AQUAJET ARV Aquajet RV Series Water Pump

If you have a larger RV or need to deliver water pressure to several areas at the same time, the Remco 55 Aquajet is your best option.

This RV water pump produces 5.3 gallons of water per minute, which is nearly twice as much as our other options. Or, the energy-saving option delivers 3.5 gallons per minute.

The Remco 55 has state-of-the-art electronics that adjust the output according to demand. What this means for you is that there is enough water pressure to wash dishes while someone is in the shower. It also means that, like the Lippert, this pump is quieter when running.

All of the technology also means a larger housing. Be sure to measure your area to see if the Remco 55 fits as a replacement.


  • Can run several fixtures at once
  • Quiet
  • Variable operating speeds


  • More expensive option
  • May be too big as a replacement for some RVs

Best for Small Campers


Seaflo 12V DC 1.2 GPM 35 PSI 21-Series Diaphragm Water Pressure Pump for Caravan/RV/Boat/Marine

Now that we’ve taken a look at all the bigger RV water pumps, it’s time to look at one designed for pop-ups, tear-drops, and other smaller campers.

The Seaflo-21 is the perfect water pump for smaller rigs that don’t require as much water pressure. At only 1.2 GPM and 35 PSI, it will work well to wash dishes and fill the toilet. But, that’s not a lot of pressure for a shower, or to wash dishes and shower, or flush the toilet at the same time.


  • Small size for smaller campers
  • Very quiet


  • Low flow rate
  • Low pressure

When it comes to replacing your RV water pump, size matters. Most of the choices listed above are made to replace a standard RV water pump and fit in the space provided. However, you should always measure your space just to be sure. Water pumps like the Remco 55 are made for larger rigs, and the Shurflo-21 is made for smaller rigs. These may not fit properly in an average RV.


The RV water pump pressurizes your system to provide water to your fixtures. It’s measured in pounds per square inch or PSI. A PSI of 35 is common for most RVs. However, there are exceptions. Be sure to check your owner’s manual so you can take advantage of as much water pressure as your system can handle!

Flow Rate

One of the specs on your new RV water pump will likely be GPM, which stands for gallons per minute. This is the number of gallons per minute that your pump can process. The typical range is 3.0 to 5.5 GPM. Larger rigs are generally set up with water pumps with a higher GPM that can service more than one fixture at a time.


All water pumps make noise, which is a good thing because then you know your pump is working. Most manufacturers don’t give a measurement of the noise level on their water pumps, so reading reviews and asking other RVers about their experience is the best option here.

RV Water Pumps Frequently Asked Questions

How does an RV water pump work?

Closeup of water running from a shower head.

RV water pumps are used when you’re not hooked up to a water supply and are pulling water from your fresh water tank.

The pump will kick on and pressurize the lines with water. When you turn on a faucet or flush your toilet, the water is released, and the pump kicks back on to repressurize the line.

Should I turn my water pump off when I’m not using it?

Ask this question to any RVer, and the answer will most likely be 50/50 on whether or not to turn your RV water pump off when not using it.

It doesn’t hurt to leave the water pump on because it will only build up pressure when needed unless you have a faulty water pump or leak in your plumbing.

You can always leave your pump on during the day when you’re in and out and using water and then turn it off at night.

How long do RV water pumps last?

This will vary according to use, but a good RV water pump should last you anywhere from 7-10 years. As stated above, there are some ShurFlo pumps that are still working after 20 years.

Are there accessories I can purchase to prolong the life of my water pump?

There are a few items you can purchase to prolong the life of your RV water pump.

A filter system will not only keep you and your family safe from bacteria and your water tasting great; it will also help keep particles out of your water pump. This is especially important if you’re hooked to a well or cistern.

Your pump may come with a filter strainer as a safeguard against small particles getting into and ruining it. Having extras on hand is always a good idea.

A pressurized accumulator tank will help regulate the pressure in your water pump, so it doesn’t have to work as hard. This is especially helpful if you choose to keep your pump on all the time.

How do I know when to replace my water pump?

When you turn your water pump switch on and hear the pump working but not shutting off, chances are it’s time to replace your water pump.
