The Best RV Water Pumps for Your RV Water System

Written by Stephen Ryan / Fact checked by William Turner

If you love RV adventures and trips then you are probably aware of how expensive it is to pack cases of water bottles. That holds true, especially if you wish to bring packs of them in your next RV adventure. To ensure that you do not have to spend too much on water, investing in the best RV water pump is a must.

This is crucial when planning to have a consistent water supply. Such water pump is actually a great item to invest in because it is capable of taking water from the tank of your RV to your rig’s pipe system. One of its main objectives is to improve the water flow while stabilizing pressure – both of which are crucial if you are traveling in an RV.

Best RV Water Pump

Note that an average tank used for a recreational vehicle is capable of storing around 50 to 200 gallons of fresh water. With the aid of the pump, you can get the chance to consume the stored fresh water in the tank. Aside from providing pressured water, the water pump also functions by supplying a certain amount of water every minute.

Most trailers make it a point to use water pumps capable of producing around 3.5-gal of water every minute. Larger trailers, on the other hand, utilize pumps designed to produce at least 5.3 gallons of water every minute.

If you are still on the stage of deciding the perfect and the quietest RV fresh water pump then you are in luck as you are on your way towards gaining access to information that will let you know which one is the best.

What to Look for When Buying an RV Water Pump 

Still unsure what you should look for when trying to figure out which is the best water pump for your recreational vehicle? Then let these factors guide you in formulating a proper decision:

Ease of installation – One thing that will immediately tell you about the effectiveness of a particular water pump is its ease of installation. The pump should be easy and quick to install in the sense that it is easy for you to do the installation yourself. Also, ensure that the pump’s dimensions are the same as the one you are replacing.

If possible, go for small-sized and compact RV water pumps because many noticed how easy it is to install them. These small pumps only have minimal usable parts in the sense that it won’t take a lot of your time.

They are also lightweight plus easy to transport to the specific spot you intend to install them. Make sure, however, that you have all the materials and supplies needed for the installation, including a water hose, Teflon tape, and screwdriver.

Noise level – Water pumps tend to produce some noise when it operates because of the motors incorporated into them. That’s the reason why you have to assess the noise level of the water pump you are eyeing to buy before investing your money in it.

Your goal is to find a quiet RV water pump, which won’t produce too much noise even if you open several faucets simultaneously. In this case, you can go for one with a 5-chamber design, as it is known for keeping the noise produced to a minimum. Check the type of mounting used in the pump, too.

It is because some mounting systems today are capable of absorbing noise. Also, beware of pumps that have jerky motors when they operate because they tend to deliver irregular water flow accompanied by noise.

To ensure that you get a quiet pump, conduct a research about the background of manufacturers. Go for a brand, which already gained a reputation for manufacturing water pumps that operate quietly.

GPM – GPM stands for gallons per minute. It refers to the number of gallons per minute needed by your pump to supply into your RV. Avoid getting an extremely powerful one, though.

It is because bigger pumps that work harder might cause them to draw too much power from your RV’s batteries. A large one might also drain the electric system of your vehicle. You can choose smaller water pumps that are as effective as the bigger models.

It should also draw less power as it can also lead to great savings on energy and water bills. However, ensure that even if you pick a pump with minimal power, you still make it a point to do something to minimize possible wastage.

PSI – PSI actually stands for pounds per square inch. This is the water pressure recommended for your RV. You have to know the safest pressure required by your rig. One standard rule is to stick to the safe range, which is actually around 60 to 75 psi.

Vertical suction lift – This factor requires you to take into consideration the specific amount of water required by your water pump in order for it to operate in an efficient manner. If you wish to pump a minimal amount of water efficiently then choose a pump with little lift.

Such is another vital factor you should keep in mind and decide on depending on the specific spot where you will drain water.

Size – Another important consideration is the size as well as the exact location of your present water pump. Note that in a recreational vehicle each square inch of available space should be utilized.

This means that your pump may need to be tucked away in a place without or with little extra space. In case you have a tight present installation then you may be unable to upgrade to a water pump with a bigger capacity because of its large physical size.

Pump cycle – This cycle often takes place each time the water pump is tapped off. It also happens occasionally when used in a bathroom. One possible cause of it is when the pump’s rate exceeds the actual water consumption.

One thing you should take note of is that the pump needs to stop automatically each time a pressure drop happens. The moment it goes down its present value, it should be reactivated automatically.

Energy-efficiency – Remember that when a water pump operates, it tends to consume a specific volume of electricity. With that in mind, check the energy-efficiency of the pump prior to buying.

It should never cause you to spend a huge amount on your utility bills. Note, however, that you also have to assess whether the pump has enough power designed to make it supply a good water flow.

Frequently Asked Questions (FAQs)

What is the psi or the flow rate of the pump?

The psi of an RV water pump stands for pounds per square inch. It refers to the specific water pressure recommended for your recreational vehicle. The safest average range, in this case, is around 60-75 psi. It also pays a lot to gain a full understanding of the pump’s flow rate.

It refers to the amount of time spent by the water pump to pump a certain amount of motor. In most cases, this figure is measured based on gallons per minute. A camper or trailer can operate by using a water pump capable of producing around 3.5 gallons per minute.

If you own a larger RV or motorhome, though, consider getting a pump that can supply at least 5.3 gallons every minute.

What is an on-demand pump?

An on-demand system is what’s usually used in an RV water pump. Investing in an on-demand RV water pump means that it only runs when necessary. It functions by putting pressure on the water pipe based on the preset pounds per square inch (PSI). In most cases, the pump operates at around 30 PSI but most of them are adjustable.

Once you switch on the power of the pump, it begins to pump. It will continue to operate and provide the required water as long as there are faucets that are open. Once you shut off the faucet, expect the pump to continue running until the predetermined water pressure is reached. It will then turn off automatically.

Such pressure will be maintained until the time a faucet is opened again. In that case, the pump will detect a drop in pressure, causing it to start pumping again.

Do you need to replace your RV water pump?

Yes, RV owners must buy a suitable RV water pump replacement if their existing device is no longer functioning properly. Some RVers also replace their pumps with quieter and more efficient units.

Most families get new travel trailer water pumps if they notice inconsistent pressure or delivery. For example, opening the kitchen faucet should provide a constant and continuous water flow. Unusual noises and leaks from the water pump can also indicate an impending device failure.

Older RV motorhome water pumps are less efficient, drawing more electricity than contemporary designs. Some are also noisy during operation, which can be a nuisance for some people.

How to replace your RV water?

Replacing a fresh water pump for RV involves multiple steps that RV owners must observe to the tee. The procedure is as follows.

  1. Turn off the water source if it’s still connected before switching off the RV water pump.
  2. Open the RV 12-volt electrical panel and remove the RV water pump fuse.
  3. Open one or two faucets to reduce pressure within the RV plumbing network.
  4. Disconnect the latching controller from the RV water pump, if there’s any, by removing the ground wire first and the positive lead next. If there’s a yellow wire, disconnect it.
  5. Loosen and remove the water lines (inlet and outlet) from the RV water pump.
  6. Loosen and remove the screws or bolts securing the water pump.
  7. Remove and clean the water pump inlet filter.
  8. Install the newly-cleaned inlet filter into the new RV water pump.
  9. Get the new RV pump and secure it with bolts or screws.
  10. Reconnect the water lines to the new RV water pump.
  11. Reconnect the latching controller to the new RV water pump.
  12. Reinsert the RV water fuse into its slot and turn on the new water pump.

Which voltage should I choose?

Most RV water pumps operate on a 12-volt electrical system. Hence, RVers can choose a 12-volt water pump for travel trailer units and install it in their motorhomes.

People can also check their existing RV water pumps for their voltage rating if they intend to replace them. These devices have metal plates or stickers on their bodies containing the product’s technical specifications.

Alternatively, RV owners can look at the motorhome’s electrical panel. There is a good chance their RV water pump runs on 12 volts if they see a fuse on the water pump fuse slot.

What is included in the water pump?

The fittings and accessories included in a water pump vary based on the model or brand you have chosen to buy. It is mainly because while there are brands and models that already have the mentioned inclusions, there are also those that do not have them.

In some cases, you will receive a straight barbed fitting along with the RV freshwater pump. Some pumps are also offered complete with all the accessories and hardware needed for their installation. Some suppliers, however, offer them separately, causing the need to invest in them separately, too.

Why is my RV water pump so loud?

If your water pump tends to operate so loudly then it is greatly possible that it has some issues – one of which could be a faulty design and manufacturing. Note that there are manufacturers who tend to scrimp on the cost for materials and installation.

This results in compromising the water pump’s quality. The problem is that it can lead to faulty installation that might show symptoms, like loose mounts. This can lead to noise because it causes water hammer, clanging pipes, and vibrations.

Another possible issue is rapid cycling. It is greatly possible for the pump to produce noise and trigger vibrations if it runs rapid cycles. To fix this issue, it would be best to make some adjustments to the cycle settings.

It is also possible for the RV water pump to operate so loudly if it needs additional water storage. One sign that such storage is indeed necessary is when you are no longer capable of storing water under pressure without the pump causing vibrations. In this case, installing an accumulator compatible with the pump might be necessary.

How to make an RV water pump quiet?

There are actually ways for you to silence a noisy water pump. What you have to do first is turn the pump off then look for the four screws that secure it. Remove the screws. Slip a mouse pad beneath the pump then secure it again, ensuring that the screws are not overly tightened. The mouse pad is helpful in isolating the vibrations.

Locate the pipes that are rattling then turn on your water pump. Someone should assist you during this process as he/she needs to open and close a faucet while you are trying to find the source of rattling noise. Once you find it, use a half-inch foam insulation as a means of wrapping the rattling pipe.

All the rattling pipes should be wrapped with the insulation. Also, figure out if the pump tends to cycle rapidly on and off whenever it is in a low flow condition. If this happens, pulsations in the system might happen, leading to noise.

In this case, adjustments might be necessary. If the pump indeed cycles rapidly, turn the adjustment screw clockwise to raise the setting until it already runs with an off time of more than two seconds.

How long should an RV water pump run?

Since most RV water pumps operate using an on-demand system, it is safe to let it run and turn it on for as long as possible provided you do not connect it to city water. When you do not hook up to city water, your RV’s water will be pumped from the onboard holding tank.

Also, take note that since it is an on-demand pump, it will only run each time you flush a toilet or turn a faucet on. A properly functioning pump will not consume power in case no demand for water is present.


Choosing the best RV water pump should be considered as a process. That said, avoid making your choice in a rush. Make it a point to read legitimate reviews and visit forums. If possible, discuss your options with a service specialist or expert. Doing these things is crucial in making a slow yet sound and informed buying decision.
