What Is an RV Water Pump? How Does It Work?

An RV water pump is an essential piece of the RV water plumbing system. Its purpose is to dictate the water flow throughout the entire system and to stabilize any pressure that might have built up.

Most RV water pumps work on demand, meaning that it kicks on only when you turn on a faucet or some other fixture in your RV. It works by pressurizing the pumps to the preset pounds per square inch (PSI) setting. Typically, it’s set to about 30. Although, on many of the pumps you can also adjust it to your preferred level.

When you turn on a faucet, the water pressure drops and this activates the pump. And until you turn off the faucet and the pressure rises again, the pump will continue pumping water.

However, older water pump models don’t have this automatic operation. And you have to manually turn them on every time you need to use water.

Benefits of an RV Water Pump

  1. Constant water supply. Any RV needs a reliable water supply. You can of course connect to an outside source but that is not always convenient. Instead, most RV owners install a fresh water tank, so that they can have a consistent supply of water, even when they are boondocking and far away from any water source. And in this case, it becomes necessary to install a water pump, which will ensure that your taps always have water.
  2. Space saving. Unlike other types of water pumps, RV pumps usually come in smaller and lighter designs. This makes it easier to install them without the unit taking up much space for your recreational vehicle.
  3. Save energy. Most of these water pumps you can connect to your RV’s battery. They connect to a 12V DC system and they offer efficient performance with low amperage draw.
  4. Easy to install. RV water pumps are also very easy to install that anyone can do without any professional help. With just a few steps you can connect the pump and start getting water to your faucets, showers, or toilets.

Types of RV Water Pumps

There are two types of RV water pumps. Ones that connect to a 12V system and those that connect to a 24V system.

  1. The most common type used in recreational vehicles is a 12V water pump since it’s the electrical system most RVs have. Typically, these 12V pumps come with motors that are specifically designed for use in RVs, trailers, and motorhomes. And in most cases, they are not meant for use in other applications, such as home water supply systems and others.
  2. A 24V water pump is rarer in RVs and it’s more applicable in buses and trucks. The main advantage of this type of pump is that it’s capable of delivering the high water pressure required for heavy duty tasks.

How to Choose the Best RV Water Pump? – Buying Guide

As with choosing any other product, it’s best to start by learning all the essential factors that contribute to a high quality purchase. And choosing an RV water pump is no different. Especially when there are so many different options available on the market, how do you choose the best one? That’s where our comprehensive buying guide should come in handy. In this guide, we’ll look at all the factors that you should take into account in order to choose the best RV water pump that would also be the most suitable option for your requirements.

Voltage

As we’ve mentioned above, RV water pumps come in two types: 12V and 24V. And it’s important to understand which one would be more suitable for your rig.

In most cases, it’s better to go with a 12V pump since it’s the standard design for RVs. It will efficiently pump the water without drawing too much power from the electrical system. Moreover, since the 24V models provide higher pressure, it can also cause issues with your pipes.

On the other hand, if higher pressure and more powerful performance are what you’re looking for, a 24V water pump can also be a good option. However, they are more suitable for larger rigs. And if choosing one of these systems, keep in mind that they all have a higher power draw, which can quickly drain your RV’s battery, solar, or generator.

So, if you want to save energy and save money on electrical bills, a 12V system should be adequate in most situations. But it’s up to you to decide which voltage fits your particular application.

Pressure

Another important factor to take into account before making a purchasing decision is the pump’s pressure. It’s essential that the water pump you choose matches your RV’s needs.

You can consult your RV’s manual to understand what is the recommended psi rating for your particular vehicle. Usually, it’s in the range between 50 to 70 psi. If you have a 2009 or newer RV model, the recommended psi rating would be about 60 psi. If it’s an older model, it should be no more than 50 psi. This is due to the fact that the newer RV models have slightly narrower pipes and so they require higher pressure to run efficiently.

With that being said, do check your manual to see what is the pressure rating for your specific vehicle model.

Water Output

GPM or gallons per minute should also be a determining factor for choosing a good RV water pump. It refers to the gallons of water per minute that the pump is capable of supplying to your RV’s fixtures. And you can find water pumps on the market that can supply anything between 1 GPM to 4 GPM.

When choosing the right GPM rating, taking into account your water demand and the size of your rig. The higher the demand and the bigger your RV, the higher GPM you should be looking for. Anything lower than 1 GPM will be just a trickle of water that is too weak for anything. And anything higher than 4 GPM will be too powerful for most systems and can also be damaging to your pipes.

However, it’s also important to point out that a pump with a higher GPM will also draw more power and will usually cost more.

Automatic Pressure Switch

A good RV water pump will also include an automatic pressure switch, which most newer models include in their design. It works by automatically starting to pump water once preset pressure values are achieved or more precisely when the pressure goes below a preset value. And it automatically turns off when you turn off the water and the pressure rises to a certain level.

The benefit of this feature is a seamless operation that doesn’t require manually turning the pump on and off each time you need to get a supply of water.

Noise Output

Water pumps can be quite noisy and it’s not something you want to hear when trying to enjoy some peaceful time in your RV. That’s why your goal should be to find the quietest RV water pump that won’t produce too much noise even if you’re running several faucets simultaneously.

One way of finding a quiet pump is by checking its construction design. Manufacturers often use special mounting systems that help to absorb vibration noise and make the pump’s operation quieter.

On top of that, you can also check users’ reviews. If a pump is unbearably noisy, you’ll definitely read about it in the reviews.

Energy Efficiency

You don’t want the water pump to be constantly draining your battery. To avoid that, choose a model that is more efficient with a low amperage draw. Keep in mind also that if you’re choosing a model with a higher GPM rating, it will also mean a higher current draw.

Ease of Installation

It’s also important to consider the ease of installation of your new RV water pump. The process should be quick and it should be simple enough for anyone to do without any professional help.

To ensure that the process won’t be too complicated, make sure that the replacement water pump you’re buying is matching your old one. The mounting hardware, size, and fittings can differ for various models. So, to avoid having to purchase extra parts and to make the installation less complicated, look for the right replacement.

Another factor that contributes to an easier installation process is if the pump comes with all the installation hardware included in the package. This will ensure that the pump is ready for set up and use right out of the box.

RV Water Pump Troubleshooting

RV water pumps often cause plenty of problems along the way of their lifespan. These units might not be very expensive but you don’t need to purchase a new one every time something goes wrong. So, before you decide to throw out your pump and get a new one, here are a few RV water pump troubleshooting tips.

Motor Failure

If your RV water pump is not working because of motor failure, there’s a high chance that you might need an entirely new pump. It could be a blown fuse or could be that the motor has died completely.

The water pump runs but no water comes out

First, check if you actually still have water in your fresh water tank. Check your tank’s gauge and if it’s low or even empty that could be your explanation.

If you do have water in your tank, the next step is to check the water lines leading to and from the pump. And start with the one leading to the pump.

Get ready a bucket, so you could catch any water coming out of the lines. Then, slowly loosen the water line from the suction side of the pump. If you see water leaking from the loosened line, this means that you do have water coming to the pump. In this case, retighten the line and move on to the next step.

If, on the other hand, you don’t see any water coming and the loosened connection stays dry, then you know that there’s no water getting to the pump, so the problem is in that water line. There could be a blockage or tube damage.

To re-establish suction in the pipe, refill it with water. Connect it to the pump and turn it on. Check if the water starts running from the faucets. If there’s still no water, then you might need a new motor or a whole new unit.

The Pump/Switch Is Leaking

If you see a trickle of water coming from the pump head or switch, the problem could be in loosened screws. Try to tighten them a bit and see if that helps. If it doesn’t, the pump might have a ruptured or punctured diaphragm.

Loud Vibrating Operation

The most common cause of loud vibration operation of a water pump is in the installation. If a water pump is loose, it will cause more vibrations. To avoid this, make sure that the pump is secure and not loose. Also, consider adding rubber padding under the pump and wrapping all your water pipes with foam pipe insulation. This will considerably help to quiet the operational noise of a water pump.

Pump Won’t Shut Off When Faucet Is Closed

If your RV water pump keeps running even though all the faucets in your recreational vehicle are turned off, start by checking your plumbing system for any leaks. Inspect the output side of the plumbing and check if there are any leaky valves.

Other possible causes can include trapped air in the outlet side, loose drive assembly, or stuck debris that is keeping the pump valves open.

RV Water Pump Tips

  • To prolong your plumbing system’s life, you might want to install a water pressure regulator. High pressure can be damaging to water pipes and a pressure regulator will make sure that the pressure stays within safe levels, which will protect the plumbing system.
  • It’s advisable to also add a high quality water filter. First of all, it will protect the pump from any debris getting into it. And secondly, it will ensure that your water is clean and safe for drinking.
  • Regularly perform checks of your pump. Make sure that there are no leaks and that the pump is not cycling when the faucets are shut off.

RV Water Pump FAQs

What does an RV water pump d0?

An RV water pump pumps water from your RV’s fresh water tank and delivers water to all the fixtures in your RV, such as faucets, toilet, and shower.

What are on demand pumps?

On-demand pumps are those that deliver water only when needed. The pump works by putting pressure on the plumbing system according to the factory preset psi. And if you open a faucet, the pressure drops and the pump starts pumping. And it will continue pumping as long as you have the faucet open.

What is the psi of a water pump?

The psi rating stands for pound per square inch. And it refers to the water pressure that is created in the plumbing system.

What causes water pump motor failure?

The most common cause of pump motor failure is a blown fuse. In this case, you can take apart the motor and replace the fuse. Another reason could be a worn out battery. In this case, try replacing the battery. And one more reason could be that it has come to the end of its lifespan. And this would require replacing the entire motor.

How to quiet an RV water pump?

There are a few things that you can do to reduce the operational noise of a water pump. First, you could start by choosing the right water pump with the least operational noise output. Secondly, you could add rubber padding under the pump installation. And thirdly, you could build a soundproof box, which would insulate the noise.

But why is your RV water pump so loud? The reason could be the faulty design or manufacturing of the pump. Another reason could be rapid cycling, which would trigger more vibrations. To fix this, try making some adjustments to the cycle settings.

How to prime an RV water pump?

To prime a water pump, start by disconnecting the outlet line from the pump. This is the line that goes out of the pump and into the RV to feed the sinks and showers.

Next, slip the collar off the outlet line towards the end of the rubber hose. Find the outlet that spouts on the pump and connect the rubber hose to it.

Fill a jar with about 12 oz of water. Bring the hose that you have attached to the outlet spout up in the air, so it would be above the level of the pump. And pour the water from the jar into this hose.

Cover the top of the hose with your thumb and turn on the pump. Give it about a minute, so it would build up pressure and when you will feel the water pressing against your thumb, turn the pump off.

How to repair a leaking water pump?

If you turn off the faucets in your RV but the pump keeps running, there’s a good chance that there’s a leak somewhere. It can be a real nuisance and it should be fixed immediately.

The most common cause of a leaking pump is a broken check valve. This is the valve that tells the pump when to stop pumping water. If there’s a crack, it will make the pump keep pumping. To fix this issue, try the following:

  1. Turn off the water and remove the old check valve from the hose that connects the pump to the fresh water tank.
  2. Install a new check valve onto the same hose that connects to the fresh water tank. Make sure that the arrow on the valve is pointing in the direction of the fresh water tank.
  3. Connect the other end of the new check valve to your water pump. Make sure that it’s securely connected.
  4. Turn on the water and see if the leak continues.

If replacing the check valve doesn’t solve the problem, the issue could be with cracked water lines. Damaged lines can depressurize the pump and encourage it to keep pumping.
