As long as it is functioning properly, the water pump on your RV might be a somewhat unimportant equipment.

When it doesn’t.

The water pump that comes with your RV or camper is a very crucial piece of equipment.

It will transport drinkable water from your freshwater tank to your toilet, faucet, and showerhead.

It will also make your toilet flush properly.

You don’t need an RV water pump if you’re hooked up to a city water connection, but if you’re not, you’ll need one to keep the freshwater moving through the plumbing system of your motorhome or travel trailer when you’re not hooked up to a water source.

Your recreational vehicle can continue to function normally if you’re hooked up to a city water connection.

You will be relieved to know that RV fresh water pumps are not too costly, and their replacement is not overly difficult either, provided that you make sure to get a type that is able to withstand the pressure that is generated by your RV’s system.

If your 12-volt on-demand water pump has broken down and needs to be replaced, or if you want to upgrade the one you already have to a booster type that will increase the water flow rate and pressure coming out of your taps, then keep reading.

You may be wondering Which water pump for a 12V RV is the best one to buy?

The first thing you need to do in order to find an ideal 12-volt water pump for your RV is to make sure that the pump you purchase will fit in the location where your previous pump was put.

How to Choose the Most Effective Twelve-Volt Water Pump for Your Recreational Vehicle

In order to choose the water pump that is most suited to your requirements, you will need to be able to differentiate between the many features and parameters that it offers.

When contrasting and analyzing the performance of various 12v water pump models, it is important to take into account a variety of fundamental aspects, which I will discuss in detail in the following buying guide.

Different Types Of RV Water Pumps

The kind of power source that is required for an RV water pump to function properly is the primary distinction between models.

Now that we have established that, let’s devote some of our attention to comparing the 12-volt and 24-volt water pumps in terms of their benefits and drawbacks.

12-Volt RV Water Pump

The majority of portable RV water pumps operate on a 12-volt system.

In general, these models have a lower pressure compared to those that have a greater voltage.

Having said that, they are designed exclusively for use in mobile homes and RVs, and are equipped with fairly ordinary motors that are capable of driving the device.

This particular kind of water pump is also suitable for use with the vast majority of available recreational vehicles.

24-Volt RV Water Pump

A water pump that operates on 24 volts is an excellent choice for those who have a serious need for increased water pressure.

Owners of recreational vehicles who need a water pump with a high level of performance should think about purchasing a 24-volt unit, despite the fact that these pumps are more often found in trucks and buses.

24-volt water pumps, although being built to undertake harder jobs, often need more frequent maintenance than their 12-volt counterparts.

This is because 24-volt water pumps are meant to manage higher workloads.

These devices, when used often, have a higher risk of being clogged if they are not regularly maintained.

They also require more power, which means that you may not be able to operate your water pump together with a number of other RV appliances at the same time if you have one of them.

Because of the potential for higher water and power expenditures associated with their usage, 24-volt pumps are not advised for use in recreational vehicles, despite the fact that they have the potential to have a longer lifetime provided they are properly maintained.

#1. The Amount Of Energy That Is Used

When you turn on your water pump, it will use a fixed amount of power regardless of how often you use it.

Because of this, you need to exercise caution when selecting a pump to ensure that it does not exceed the capacity of the electrical systems in your RV.

Fortunately, recreational vehicles (RVs) are built with the capability to power a water pump in addition to a number of other equipment.

This is true regardless of whether the connection for your RV is 30 amps or 50 amps.

Having said that, it is beneficial to be aware of the energy needs of your water pump in order to prevent blowing a fuse by simultaneously operating your pump and an excessive number of other appliances on the same circuit.

Knowing the energy requirements of your water pump is easy to do.

A water pump that uses more power will run down your battery more quickly, and you will go through more water as a consequence.

This is an essential point to keep in mind since it will determine how often you have to top up the water and make sure that the battery in your home isn’t depleting to an unsafe level on a regular basis.

#2. Voltage Requirements

The 12-volt or 24-volt category is where you’ll find the vast majority of water pumps.

However, there are very unusual cases that have significantly differing power needs.

Make sure that your recreational vehicle (RV) is able to provide the amount of voltage that the water pump requires in order to function properly before making a final decision on which water pump to purchase.

Because 12-volt water pumps are compatible with such a wide variety of recreational vehicles (RVs), I decided to include them in the evaluations shown above.

Despite the fact that bigger 24-volt versions are more often found in larger buses and trucks, you will still need to verify that your recreational vehicle is capable of meeting the voltage requirements of the pump you are interested in purchasing before making a final decision.

#3. The Amount Of Noise Generated By The Clean Water Pump

Because they rely on the running of a motor to perform their tasks, all water pumps will emit some level of audible noise.

But there are certain types that are far more quiet than others.

Finding a model of pump that isn’t going to be too loud and obnoxious while it’s operating will be easier for you to do if you compare the sound output of several types.

Water pumps for travel trailers and motorhomes, such as the Remco Aquajet, that have a five-chamber design are, in general, the quietest types available to consumers today.

Even if you open many faucets at the same time, these pumps usually continue to run in a quiet manner.

The volume of your water pump’s operation is also influenced by how you put it on your system, so pay attention to this detail.

When the pump is in operation, the amount of noise that is generated may be reduced by using mounting solutions that are specifically designed to absorb vibrations.

Reading the reviews that other people have left for a particular kind of pump is another another approach to figure out how loud it is.

Some pumps result in unexpected levels of flow (i.e. faster and slower at unpredictable times).

Typically, this is the result of a jerky motor, which in addition to creating more noise than a motor that is operating smoothly, also causes greater vibration.

It is a good idea to look into pump manufacturers that have a well-known and respected standing in the business in order to increase the likelihood that you will get a pump that does not produce an excessive amount of noise.

Water pump manufacturers with a strong reputation include Shurflo, Remco, Arterra, Seaflo, and Flojet, among others.

#4. The Automatic Switching Capability

The majority of pumps are equipped with an automatic switch option; nonetheless, it is essential that you verify the presence of this feature before you go on to researching other water pump types.

Because of this function, the pump will automatically turn off once the predetermined pressure rating has been attained.

If your pump does not have an automatic switch option, you run the danger of it continuing to operate even when it is not required to do so.

This has the potential to cause damage to the pipes in your RV and also greatly raises the amount of electricity that you consume.

A pump that is allowed to operate continuously even if it is not required to do so will have a lifespan that is much lower than one that is programmed to turn on and off only when it is required to do so.

#5. The PSI and GPM

PSI and GPM are abbreviations that stand for pounds per square inch and gallons per minute, respectively.

When comparing different kinds of RV water pumps, these are the two parameters that are considered to be the most essential overall.

Knowing the appropriate water pressure rating for your RV’s system requires that you have a solid understanding of the PSI rating of your recreational vehicle (RV).

You need to determine the RV’s maximum safe pressure before you can choose a new water pump for your recreational vehicle (RV).

The majority of rigs have a pressure tolerance of between 60 and 75 PSI, however 30 or 40 PSI is considered to be a safer working pressure.

This kind of pressure is normally within the capabilities of a water pump powered by 12 volts and developed specifically for usage in an RV.

The flow rate of a water pump may be measured in terms of gallons per minute (GPM).

To put it another way, it will tell you how many gallons of water it is capable of pumping in one minute.

It is essential to consider flow rate in order to guarantee that your system is capable of reaching the necessary pressure for activities such as washing dishes and taking showers.

Although it may seem like it would be good to have a pump that can deliver a greater flow rate for your RV at first, there are both advantages and disadvantages to having a pump that can attain a higher gallon per minute rate.

One of the primary drawbacks of upgrading to a water pump with a higher rating is the increased power consumption.

It’s true that you’ll receive more water per minute, but you’ll also use more electricity if you’re linked to the grid at an RV park or run down your battery if you’re not connected to the grid.

Pumps that need a greater amount of power to operate are able to provide a flow rate that is more than five gallons per minute.

However, the majority of recreational vehicles do not need a flow rate of nearly that high.

You won’t need anything more powerful than a water pump that can provide between three and four gallons of water per minute.

#6. Quick and Straightforward Setup

Avoid purchasing any kind of water pump that makes the installation process seem impossible to do on your own.

That does not mean that the installation is as simple as plugging things in and letting them work, but it is also not very difficult.

You will be in good shape if you make sure that all of the water in your rig is turned off and that you strictly follow the installation instructions provided by the manufacturer.

Be certain that the replacement pump you buy has the same size as the one it will replace, as this is one thing that will make the process of installing it much simpler for you.

This way, you won’t have to worry about whether or not it will fit where it’s intended to, and you won’t have to worry about your overall storage capacity underground being reduced since you’ll be installing a massive new water pump.

In most cases, a water pump that is lighter in weight and smaller in size will be simpler to set up.

Some of the goods that you will need for a successful installation are universal, such as a screwdriver, Teflon tape, and a water line.

The supplies that you will need for a successful installation will vary based on the kind of pump that you buy.

#7. Size

This one isn’t too hard to figure out.

Be sure that the water pump you choose is the right size for the space where you want to place it before you buy it.

Taking accurate measurements of the size of the water pump you already own is the simplest approach to avoid purchasing a new pump that is too big for your needs.

If you buy a water pump that is much smaller than the one you already have, you won’t be doing as much damage as you would if you bought a model that is significantly bigger than the dimensions of the pump you already have.

#8. Pump Cycle

Every time it powers down, a water pump that is working properly should “cycle.” This should take place each and every time you turn off the water in the shower or at any of the faucets in your RV.

Additionally, it must to take place following you have completed flushing the toilet.

Even if you haven’t been using any water for a little while, you may still hear the cycle of the water pump every once in a while.

If the water pump is turned on and left on, it will cycle every time the pressure in the pipes of your RV falls below the pressure level that you have changed on the unit.

If this happens often, you may want to turn the pump off.

If the pressure setting on your pump is adjusted too low, you will most likely notice that the pump cycles more often than usual.

This will occur even if you haven’t completed running water in a very recent period of time.

Increasing the pressure setting directly on the pump is the simplest technique to reduce the number of times the pump has to cycle.

Therefore, Which Of These RV Water Pumps Is The Best Option For Your Unit?

Choose the Shurflo 2088-554-144 if you are in the market for an RV water pump; consumers of this model have repeatedly given it high marks for its performance.

This pump is capable of delivering up to four gallons of water per minute and will ensure that your water continues to flow in the manner that it was designed to all along.

The Remco 55AQUAJET water pump is ideal for anybody who is sick and tired of their water pressure fluctuating every time they open several faucets since it can supply more than five gallons of water per minute.

This pump has a variable speed and utilizes intelligent technology to maintain a constant flow rate throughout the system.

If you are searching for a long-lasting water pump that will not corrode with time, you should consider purchasing the Flojet 03526-144A since it was intentionally developed using materials that are resistant to corrosion.

Additionally, this pump is fitted with a bypass valve that lessens vibration and ensures that it operates in a more quietly and smoothly.

Its water delivery rate is roughly three gallons per minute.

The SEAFLO 21 Series pump is, in conclusion, one of the finest RV water pumps for rigs that don’t have a lot of room available inside of them.

This pump has a very low weight and is designed in an extremely space-saving manner.

It also has a very low amperage consumption, which ensures that the electrical system in your RV will not be overworked.


I really hope that you’ve narrowed down your options for the future water pump by now.

However, in the event that there is still some degree of ambiguity about RV water pumps, the following are some of the answers to the questions that are asked the most often.

What exactly do the terms “PSI” and “flow rate” mean?

PSI is an abbreviation that stands for “pounds per square inch.” It is a gauge for determining the ideal water pressure for your recreational vehicle.

You should purchase a water pressure gauge if you want to verify the pressure that is coming out of a new municipal water connection before you connect it to your RV, even though the majority of recreational vehicles run within a safe pressure range of 60 to 75 pounds per square inch (PSI).

The length of time that is needed for a pump to move a certain quantity of water is referred to as the flow rate.

The majority of pumps use the gallon per minute measurement to determine flow rate.

The majority of recreational vehicles need for a water pump that has a minimum flow rate of 3.5 gallons per minute.

On the other hand, some more substantial trailers or recreational vehicles (RVs) need for a water pump that can transport at least 5.3 gallons of water per minute.

Why are some of these pumps referred to as “on-demand” pumps?

Pumps that operate on demand do not operate until it is absolutely required to do so.

The majority of RV water pumps function in this manner as the normal mode of operation.

To activate the pump, you must first find the switch that controls it, which is often situated someplace within your RV.

As long as any of the faucets are left open, the pump will keep delivering water to them even after the switch has been switched on.

Even after all of the taps have been turned off, the pump will continue to operate until it achieves the desired level of pressure.

After that time, it will continue to be turned off automatically until the faucets are opened again, at which point it will sense a reduction in pressure and turn itself back on.

In the event that a reduction in pressure is noticed, an on-demand pump will start pumping once again.

The water pipes in your RV are pressurized by this kind of pump depending on the PSI rating that you have selected for the pump.

The majority of on-demand pumps have a pressure rating of around 30 PSI that is pre-set but may be modified according to the preferences of the user.

What kind of voltage should I go with?

Although it may seem appealing to go for a 24-volt water pump that is more “powerful,” it is important to keep in mind that these pumps are often meant for automobiles such as trucks and buses.

Because 12-volt electricity is standard in RVs, it is in your best interest to go with a pump that operates on that voltage so that you may avoid having to make any adjustments to the electrical system in your RV.

Is there a way to reduce the noise level of my water pump?

The majority of RV water pumps are not very noisy, but each one does produce some level of noise.

Investing in a water pump silencer or even just making some little adjustments to the way the pump is mounted will help you achieve your goal of making your water pump much quieter.

When the pump is operating, one effective strategy for reducing vibration is to position a thin pad below it before tightening the screws that hold it in place.

This is an excellent method for reducing the noise produced by your water pump, but only if you take care not to overtighten the screws.

Because they cycle so quickly, some pumps may be quite irritating.

This is often brought on by a low pressure setting, which may be corrected by giving the pressure adjustment screw a very little turn in the clockwise direction.

Adjusting this setting such that the pump stops running (or at least stops making noise) for at least two seconds between cycles is a decent rule of thumb to follow.

How long do these water pumps remain operational for?

To continue pressurizing your water pipes, the on-demand water pumps may be switched on and kept on as long as you are NOT connected to a municipal water connection.

This is the only condition that applies.

On the other hand, it is best practice to switch on and off your water pump on an as-needed basis.

Because it doesn’t take these pumps very long to pressurize the water pipes in an RV, you can switch them on just before you need water and then turn them off again when you’re done using them.

In light of the aforementioned, an RV water pump that is in good working order will only operate when either the sink faucet or the toilet is flushed.

If there is not an immediate need for pressure, it will not continue to run and waste power if it thinks there may be a need in the future.


Taking care of the water pump in your recreational vehicle (RV) may not be the most exciting aspect of owning an RV.

Living in one without the convenience of running water won’t be very enjoyable, that’s for sure.

If you’re anything like me, you could even consider purchasing an additional water pump so that you’ll be prepared in the event that anything goes wrong with the one you already have installed.

Whether you need a new RV water pump because something went wrong with your old one or you’re simply making preparations for the future, the eight RV water pumps listed below are among the finest that are currently on the market.

I really hope that you have found these evaluations to be enjoyable, and that the advice provided on how to choose your subsequent RV water pump has been of use to you.
