Shurflo gets confusing when it comes to their warranties.

Overview Of RV Water Systems

Best RV Water Pump

From troubleshooting and repairs to water pressure and more, we’ve covered everything you need to know about your water pump from top to bottom.

They’re a fairly straightforward to install and manage, once you get your hands dirty.

Without further ado, let’s hop into it.

Why Do You Need Water Pumps?

Your water pump dictates the flow of water throughout your entire system.

Water pumps generally last a long time, which is why you’ll see many inquiries online about purchases regarding older mobile homes.

You can have it last for ten or fifteen years, even if you’re a full-time RVer.

You always need a water pump, but as life takes you by the hand and you end up with more and more passengers in your RV, you need a higher capacity. Water pumps have a GPM, or gallon-per-minute rating that dictates how much water comes out of your system.

Whether you need to empty your system to replace a fresh water tank or you simply want more efficient showers, your water pump is the MVP.

Water pumps dictate the pressure, more or less.

They’re essentially the check and balance system for your water, keeping you from exerting too much water pressure, and optimizing flow to lower water waste.

How Much Power Do RV Pumps Take To Drain?

Pouring Water In RV Sink

Your pump pushes water into the heater, into the pipes for cold water, and of course, handles everything that’s currently trapped in your pipes.

You can find out how much power it takes by determining the capacity it has, your RV water heater capacity, and accounting for roughly one to three gallons of water in your pipes.

Multiple the gallons by the amp usage, and the gallons-per-minute rating on your RV water pump.

Using the amp power rating, determine how many gallons of water it can pump per hour, divide it by how much water you’re going to be dumping (be sure to include the total number of your fresh water reservoir), and you’ll find your answer.

We would like to provide a simplistic way to tell, but since different units use different power levels and pump different volumes of water, it needs to be done by your calculations.

RV Pump Troubleshooting

While your water pump is one of the most crucial components of your RV, you’re going to encounter tons of problems along the way.

Your water pump isn’t the most expensive aspect of your RV’s inner workings, but that doesn’t mean you need to purchase another one when it’s on the fritz.

The water pump undergoes plenty of stress, which is why we’ve answered some of the most common problems, and how to fix them.

Most Common RV Water Pump Problems

Regardless of how much you spend on an RV water pump, you’re going to encounter issues while using it.

It’s part of the RV journey.

That’s why we wanted to address the most common issues, and how to fix them without having to redeem your warranty, or undergo an expensive repair or replacement by a professional.


Holding Water Pump Parts

This is one of those issues no RV owner ever wants to encounter.

You could have blown a fuse, or the pump motor could have just died.

It really is a 50/50 gamble on this one. You can check by flicking the master switch and charging the battery.

Otherwise, we are very sorry for the loss of your RV water pump motor.


The most likely culprit of this common issue is a low water level in your tank, or clogged water lines.

You can fix this quickly by refilling your tank and then running the water straight through. This would obviously be ideal to handle at an RV stop station or at home before you head off on your excursion.

In rare circumstances, you might need to replace the clean valve, check the wiring on the pump, or replace the belt.


There’s a leak somewhere.

Whether it’s a faucet or a water line, your pump is slowly being tricked into thinking that the water is running, when in fact nothing is happening. You might have to replace the faucet sets or valves, but you should also check out the pressure switch.

You might not be getting enough pressure from the pump, at no fault of the pump itself.


Installing RV Water Pump

During your installation, you came across the intake line.

There could be a kink in the hose preventing proper flow, forcing water to back up into your pump and pressure to build. That can also be part of the next issue, being loose bolts and a shaky housing for the motor.

You can fix this by inspecting the unit, ensuring the hose is properly laid out, and tightening all your hardware to keep the pump in place.

So long as it’s functioning as it should, tightening everything should do the trick.

Average Gallon Use Per Day

Water Pouring

We’re always trying to create the most efficient RV possible.

You’ve no doubt spent hours upon hours finding more ways to conserve energy, water, and prolong the life of your RV’s internal components.

One way to get the most out of your water pump is to monitor the maximum gallon use per day.

There’s rarely some stamp on a water pump that showcases exactly how many gallons it can pump through it in one lifecycle. What we know from common sense is that the more you use something, the faster it deteriorates, until it eventually breaks.

Your water pump is designed to withstands thousands, possible tens of thousands of gallons running through it.

Find out your average gallon usage per day, and strive to minimize it.

Despite getting an upgrade on your water pump, mitigating your daily water use is a surefire way to lengthen its life expectancy.

Here are some tips on how to use less water in your RV, and maximize your water pump’s life:

  • One-Gallon Shower: One open secret is to take one-gallon showers, and not a drop more. It’s a controversial topic for RV owners, because if you only took a one-gallon shower at home, it would feel like you were barely rained on. Apply soaps and shampoos before you step into the shower, use one cup of hot water to begin cleaning yourself, and then hop in to use the rest of that gallon in the shower. It’s not the most pleasant experience, but it will lower your water use.
  • Bring Body Wipes: Mitigate water use with in-between baths, using body wipes. Not baby wipes, not dime-store moist towelettes, get something like Paper Shower that’s designed for RVers. You can also save water by using biodegradable soaps.
  • Cold Flow Collection: Just like at home, when you kick on the hot water, you get that initial cold water flow. Save that in a pitcher to purify for drinking water (so you don’t use the tap), or save it to use for dishes later on. You can save an average of twenty-seven gallons of water from cold flow per year, if you RV full-time. You increase pressure without using more water, effectively reaching your RV’s needed psi, and holding onto extra gallons throughout the year.

Last but not least, upgrading your water pump to a more energy-efficient system.

What You Need To Know About Water Pressure

You should already have a water pressure regulator.

If not, one may have come with your water pump, or you can make a separate purchase.

Water pressure is going to dictate everything that goes on in your RV: the sink, shower, even the pressure of the toilet flushing (if it’s integrated).

Your water pressure should be about 60 psi if you have a 2009 or newer RV model.

This was when newer base systems were introduced with slightly narrower pipes, though they require higher pressure than older RVs to run efficiently.

If you have an older RV, you should have no more than 50 psi. Older systems have less pipes running, and 60 psi could blow the system.

Your water pressure is partially going to depend on how many gallons per minute your water pump is able to handle.

Putting your water pump through its paces can cause long-term damage, so it’s best to grab one with enough capacity to handle your family size.

Plan ahead, and you’ll get extended use out of it.
