What is a 12v RV Water Pump?

An essential component of any RV’s plumbing system is the 12v RV water pump. 

Operating on a 12-volt power source, this specialized pump is designed to draw water from the RV’s storage tanks and deliver it to various outlets, such as taps, showers, and toilets. 

When you turn on a faucet or use any water outlet, the pump senses the pressure drop and springs into action, ensuring a steady and reliable water flow while on the road.

How Does an RV Water Pump Work?

The operation of a 12v RV water pump is relatively straightforward yet crucial for maintaining a constant water supply. 

When you open a faucet, the pressure within the RV’s plumbing system decreases. 

A pressure switch in the water pump detects this drop and activates the pump to start working. 

The pump draws water from the storage tanks and pushes it through the RV’s plumbing system, ensuring water reaches all outlets.

As the water flows into the system, the pressure builds up again. 

Once the pressure reaches its preset limit, the pressure switch senses this change and shuts off the pump. 

This process helps maintain water pressure within a set range.

The pump remains off until another pressure drop is detected, which happens when you open another faucet or use another water outlet. 

This cycle ensures a reliable water source throughout your RV, making your travels more comfortable.

The operation of a 12v RV water pump is relatively straightforward. 

Once you turn on the faucet, the pressure within the system decreases. 

The pressure drop is detected by a pressure switch in the pump, which then triggers the pump to start working.

How to Choose the Right 12v RV Water Pump

We believe that our top pick, the SHURflo Revolution, will be the best option for most users.

However, it’s unrealistic to expect that any single pump would be ideal for every single situation, so rather than blindly trusting our judgment, you should do your own research.

When it comes to buying a 12v RV water pump, there are several factors to consider ensuring that you choose the right pump for your specific needs.

Here’s a comprehensive guide to assist you in your buying process.

Pump Type

Generally speaking, there are three different types of RV water pumps:

  • constant speed,
  • variable speed, and
  • high volume. 

Most of the options you’ll find are constant speed; this means that the water only comes out at a single speed, and you can’t really adjust it one way or the other.

These pumps are generally inexpensive and get the job done well, but they may not give you the luxury you’re accustomed to.

Variable speed pumps, on the other hand, can alter the flow of water depending on your needs. That means that, if you turn on the faucet a tiny bit, the pump will only give you a tiny bit of water.

These pumps are usually quieter than their constant-speed counterparts, but they’re more expensive, too.

High-volume pumps can move a lot of water quickly — often over 4 gallons per minute.

They’re usually only found in larger rigs with massive water tanks, and they suck down a lot of electricity in order to move all that liquid.

Flow Rate

The flow rate, measured in gallons per minute (GPM), is a crucial factor to consider. It determines how much water your pump can deliver to your RV’s outlets.

A higher flow rate means the pump can deliver more water in less time.

However, it could also lead to greater water consumption, which isn’t ideal when boondocking.

Your choice should depend on your water usage. If you have a large RV or often travel with a big family, consider a pump with a higher GPM.

Pressure (PSI)

Water pressure, measured in pounds per square inch (PSI), is another important factor to consider when choosing a 12v RV water pump.

PSI refers to the force that the water has as it is pumped out of the water pump and into the RV’s system.

A higher PSI means the water is being pushed with greater force, which can be useful for activities like taking a high-pressure shower.

However, a higher PSI also puts more strain on your RV’s plumbing system and can lead to increased wear and tear over time.

When choosing an RV water pump, consider your water requirements and the durability of your RV’s plumbing system, and select a pump with an appropriate PSI.

Remember that a pump with a very high PSI might not be necessary for all RVs, especially if you don’t have high-pressure water needs.

Physical Size

Your water pump has to fit in a clearly defined space inside your RV. However, the size of these pumps can vary wildly, as some can be quite tiny while some high-volume pumps can be formidable beasts.

Before you buy a new pump, you should measure the existing space to make sure that the model you have your eye on will actually fit in your RV.

Safety Features

Water pumps aren’t really dangerous machines, so when we mention safety features, we’re talking about being safe for the pump.

This usually means some form of thermal protection that will shut the pump down before it overheats, but there are other things you might want to look for as well.

They can include sealed bodies that prevent water and debris from entering the motor, check valves that prevent water from running from the pump back into the tank, and filters that screen out contaminants before they can enter the housing. 

Safety features can increase the cost of a pump by a few bucks, but if they also extend its lifespan by a few years, it will be money well spent.

Power Supply

Virtually all RV water pumps should run off 12-volt electricity, as they’ll draw power from the RV’s 12-volt battery.

However, you may see some water pumps that say they run off 110v or 120v power.

Avoid 110v or 120v pumps at all costs — they’re made for buildings with more robust power supplies, not RVs with tiny batteries. Installing one in your rig could do a lot of damage to the electrical system.

The only exception is if you have a secondary power source that you plan to use to run the pump, like a generator or grounded outlet in a building.

If that’s the case, you can buy one of the other pumps; however, most 110v or 120v water pumps are high-volume machines designed for giant rigs.

RV Water Pump Shurflo 4008-101-A65 3.0 GPM | 12V Water Pump | Self-Prime | Camper Water Pump | RV Plumbing (1 Pump)

This small pump provides top-of-the-line performance at a middle-of-the-road price.

The SHURflo Revolution may not look like much, as it’s a small, un-intimidating device that barely looks capable of causing a ripple in your water tank, much less giving you all the water pressure you need. Looks can be deceiving, however, and you should skip this pump at your own risk.

It’s one of the easiest pumps to install that we’ve found, and even those who aren’t DIY-friendly should find the process relatively painless.

What We Liked

You can mount it in any position, so even if you’re cramped for space, there should be a way to install it that doesn’t involve taking things apart, banging your fingers, or cursing loudly in front of the neighbors children.

This is a very quiet unit, and if you have the TV on or any other sort of noise occurring, you likely won’t even be able to tell when it’s running (this does, however, leave you vulnerable to “is your water pump running?” crank calls).

It won’t cycle rapidly either, so you won’t be subjected to hearing it cut on and off repeatedly while you’re trying to sleep.

Despite its unobtrusive nature, it can ship a healthy amount of water at 3 gallons per minute.

That water will come out at 55 psi, which is more than enough for most purposes; it may not be ideal for pressure washing your rig, but it should be able to handle everything else you ask of it.

What We Didn’t Liked

Be aware, though, that this thing does draw a lot of power (7.5 amps, to be precise).

You should check to be sure that your battery can handle that kind of draw before you hook this thing up, or you could find yourself needing to replace more than just your pump.


  • Incredibly easy to install
  • Very small yet impressively powerful
  • Can be mounted in any position
  • Quiet while in use with no rapid cycling
  • Pumps 3 GPM at 55 psi 


  • Draws a lot of power

2. SEAFLO Water Diaphragm Self-Priming Pump — Easiest RV Water Pump to Install

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

This universally-fitting pump can replace — and likely improve upon — whatever you already have installed.

For many inexperienced users, the prospect of replacing a water pump is terrifying, as they dread the embarrassment that will occur if they have to slink back to the store and admit they bought the wrong pump.

That’s not an issue with the SEAFLO Water Diaphragm, though, as its industry-standard connections mean it will replace just about any other pump on the market.

It has a heavy-duty motor and a three-chamber high-volume design, which is basically just fancy talk for “it can move a lot of water.”

The Seaflo pump 3 gallons per minute at 45 psi, which can’t quite match up with the SHURflo Revolution but is still pretty impressive.

It does a good job of maintaining steady pressure, too, so you won’t have to worry about your water flow sputtering all the time.

What We Liked

This is a self-priming pump that can prime up to 6 vertical feet, so it should still work well even when your water tank starts to get low.

Don’t worry if you accidentally run out of wet stuff, either, as it can run dry without breaking down (although we wouldn’t recommend it). 

This isn’t a very loud pump, but it does tend to vibrate quite a bit. It shouldn’t be enough to keep you up at night or anything like that, but you’ll definitely be able to tell when it cuts on.

What We Didn’t Like

The vibrations get worse the more water pressure you need, so expect to feel like you’re showering in an earthquake.

Also, if you plan on hooking up a garden hose to the pump at any time, you’ll need to buy special adaptors.

That’s not a huge deal, but it’s a minor annoyance that could seemingly be avoided by including those adaptors from the get-go.


  • Should be able to replace just about any other pump out there
  • Can move a lot of water
  • Self-priming model
  • Can run dry without damage
  • Maintains consistent pressure well


  • Vibrates quite a bit
  • Requires special adaptors to use with a garden hose

3. Lippert Components Flow Max Water Pump for RVs — Most Durable RV Water Pump

Lippert Flow Max 12V RV Water Pump, 3.0 GPM, 50 PSI, 9.5 Max Amp, Corrosion-Resistant Motor, Self-Priming, Screen Filter and Connector Included - 689052

This stout pump is a long-lasting model that performs admirably.

The Flow Max from Lippert Components just looks like a serious piece of equipment, and when you turn it on, you’ll find that it lives up to its appearance.

This is a heavy-duty pump, and the corrosion-resistant motor ensures it will give you plenty of years of faithful service.

Part of the reason why it’s likely to live so long is that it has a screen that filters out debris before it can reach the motor and wreak havoc.

That also ensures that the water that comes out of your faucet is clean, even if you had to fill it up from a less-than-reputable source.

What We Liked

This is a versatile machine as well, as it can work with either a 12v or 115v power source (although you’ll likely only use it as a 12v water pump on your RV).

Regardless of which you use, it can deliver quite a bit of water — 3 gallons per minute at 50 psi.

Despite the power it produces, this is one of the quieter pumps we tested. You should barely be able to hear it, and after a while, you likely won’t notice it at all.

What We Didn’t Like

This is another power-chugger, though, as it often draws as much as 9.5 amps off the battery. It’s also not a continuous-duty cycle pump, as it can only run every 5 minutes out of 10.

This isn’t a problem for most applications, but if you like long, luxurious showers, this won’t cut it.


  • Corrosion-resistant motor
  • Filter removes debris before it reaches motor
  • Works with either 12v or 115v power source
  • Very quiet while in operation
  • Delivers 3 GPM at 50 psi


  • Draws a lot of power
  • Not a continuous-duty cycle model
Precitrade Shurflo 2088-554-144 Fresh Water Pump, 12 Volts, 3.5 Gallons Per Minute, 45 Psi

This model has been on top for over 20 years, thanks to its excellent performance and safety features.

The SHURflo RV Fresh Water Pump can produce a larger volume of water than its counterpart on this list (3.5 gallons per minute vs. 3.0), but it does so at a lower pressure (45 psi vs. 55).

There’s not really a right or wrong answer here, but most people prefer high water pressure, so we gave the slight nod to the Revolution.

It’s to be expected that the Revolution should be slightly better, though, as it’s a newer model.

That speaks to the enduring quality of this option, though, as it’s been around for 20+ years and is still one of the best water pumps you can buy.

What We Liked

The motor has a one-way check valve that ensures there’s no backflow, so your water supply won’t accidentally get contaminated.

While it may not provide as much pressure as the Revolution, the difference isn’t that noticeable, especially if you’re just running one faucet at a time.

What We Didn’t Like

What is noticeable, however, is the difference in noise.

This is a much louder pump, largely due to the fact that it uses a metal mounting bracket as opposed to encasing it in rubber.

You can try to mitigate this yourself by experimenting with various ways to pad the bracket, but it’s a problem you’ll either have to solve on your own or learn to live with.

While you’re trying to figure out a way to dampen the noise this thing makes, you may also need to swap out some of the hardware during the installation process.

The included screws are very short, and may not be long enough for many setups, so don’t be surprised if you have to swap them out before you can put the thing in.

Once you get the right gear, though, installation is fairly easy and straightforward.


  • Been one of the top models for over 20 years
  • One-way check valve prevents backflow
  • Long-lasting and durable
  • Easy to install
  • Good water pressure when running one faucet at a time


  • Very noisy
  • May need to swap out included hardware during installation process
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

This little machine works surprisingly well, especially given its budget-friendly price.

When you open the box and see the Bayite BYT-7A108 staring back at you, there’s a good chance you’ll think you brought home the wrong part.

This thing is tiny (a mere 14.1 ounces), and it doesn’t look like it could push any amount of water at all.

In actuality, though, it can create a serious amount of water pressure, as it can top off at 100 psi before automatically shutting down.

The downside is that the total volume of water is low, as it’s only capable of pumping 1.2 gallons per minute, so you’ll have to pick your poison there.

You can also adjust the pressure as needed; it’s set on about 70 psi out of the box, but you can raise or lower it as needed. 

This is one of the cheapest pumps we looked at, but despite the low price, it boasts some impressive features.

The body is sealed to prevent moisture from seeping in, ensuring you get plenty of durability from your minimal investment, and it’s self-priming up to 6 feet, allowing you to install it at the top of your freshwater tank.

Indeed, you’ll have to put it above the tank, as it can’t be submerged.

It’s also very quiet, thanks in large part to the rubber mounting tabs that dampen vibrations. You can barely hear this thing when it’s on.

That’s a bit of a double-edged sword, though, as it sometimes strains under high pressure, and if you can’t hear it struggling, you can easily burn out the motor.


  • Can create very high water pressure
  • Flow rate is adjustable
  • Body sealed to prevent motor damage
  • Very affordable
  • Rubber mounting tabs keep it quiet


  • Low volume at only 1.2 GPM
  • Can’t be submerged
  • Struggles and can burn out at higher volume

What We Looked For in the Best RV Water Pumps

Water pumps aren’t the sexiest products in the world, so it’s no surprise if you’ve never really given much thought to what to look for when you need a new one.

Fortunately, picking a new pump isn’t exactly rocket surgery, as there are really only a few things you need to look for when shopping around.

Here’s how we evaluated the various pumps that we tested:

Flow Rate

This is the amount of water (expressed in gallons per minute, or GPM) that your pump can process at a time. The higher the flow rate, the more water you’ll get when you turn on the tap. 


While the flow rate is an important metric, it’s only half the story. The other is how forcefully that water will flow out of your faucet or showerhead.

This is expressed in pounds per square inch or psi. A higher number means more pressure, but if you go too high, you run the risk of creating leaks in your system.

Power Draw

Running your water pump can put a lot of strain on your RV’s battery. Some of the pumps that offer the best performance will also suck down plenty of juice, potentially draining your battery in a hurry.

Ideally, you want a pump that works well without needing a ton of electricity to do so.


Water pumps can be extremely loud. If you don’t want to have to wear earplugs every time you take a shower, you’ll want to find a pump that can perform well without creating a huge racket in the process.

What is the average GPM for an RV water pump?

The average GPM for an RV water pump typically falls within the range of 3 to 5 GPM. However, it’s important to note that this value can vary depending on the specific make, model, and brand of the water pump. Some premium RV water pumps may offer a higher GPM, reaching up to 6 or 7 GPM, while more basic or compact models may have a lower GPM, ranging from 2 to 3 GPM. Consider your water consumption needs and ensure the water pump’s capacity matches your RV’s plumbing system.

How long do RV water pumps last?

A well-maintained water pump from a reputable brand can last anywhere between 3 to 7 years. The longevity of an RV water pump depends on several factors, including the pump’s quality, frequency of use, and maintenance. Regular maintenance, such as cleaning and timely part replacements, significantly extends the pump’s lifespan. Familiarize yourself with your water pump’s operation, as unusual noises or reduced water flow may indicate potential issues early. Addressing these signs promptly prevents further damage and ensures your water pump serves you well for an extended period.

In Conclusion

If you’re in the market for a new water pump for your RV, you can’t go wrong with the SHURflo Revolution. It’s powerful, quiet, and can provide years of faithful service.

That doesn’t mean that it’s right for everyone, though. Try to find a pump that’s capable of giving you the water pressure you need, without drawing down your battery or drowning you in noise. 

Whatever you do, though, don’t skimp on your water pump. After all, there’s no better pickup line when you’re out on the road than, “Hey baby, come back to my rig — the water pressure in my shower is amazing.”
