What Does a Water Pump Do for an RV?

While it may seem straightforward to say that a water pump does as the name presents -- pumps water -- these little units are a fundamental part to living a luxurious life on the road.

Pumps are the brains behind ensuring you have running water to flush your toilet, use your sink, and take a shower. Should your existing model die, you’ll be caught in a bind, living an extremely abnormal lifestyle.

What Makes a Great Water Pump? 

When shopping for a new water pump, there are intricate parts that all work in unison to make a great model. Companies such as Shurflo do their job to ensure you’re taken care of and remain stress free while living in your RV. To help identify the core parts of a great model, we’re going to break down three main aspects to look for when shopping.

  • Water Pressure

First and foremost, keeping an eye out for water pressure will help keep your flow regulated and consistent. Selecting the proper water pressure comes down to your specific needs, but we do recommend choosing a model that’s designed to max out around 50 PSI.  This will ensure you’re not experiencing lag when turning on the sink or taking a relaxing shower.

  • Gallons Per Minute (GPM)

With every water pump, each model is intended to produce a specific number of gallons per minute (GPM). The GPM will vary per each model, but finding that sweet spot could make all the difference in terms of output and flow. 

When matched with pressure, this provides for the ultimate ‘at-home’ sink or shower experience. Keep in mind, higher isn’t always better as it may come with a noisier unit.

  • Size

Keeping in mind where your current model is can alleviate future headaches. Sometimes, buyers will move forward with one of their dreams, then suddenly discover they have to make some DIY modifications to make it fit. To ensure this isn’t the case, we encourage you to measure your current model and align your sights with a size that’s similar; bolt patterns are often similar, but height and depth can vary.    

Quick Take - The Best RV Water Pumps

Before you go any further, here are our top picks: 

  1. Shurflo 2088-554-144, 45 PSI
  2. Pentair Shurflo 8000-543-236
  3. Amarine-made 12v

Review of the Best RV Water Pumps 

Now that we’ve identified what makes a great water pump and outlined their main functions, let’s switch gears and take a look at the products on our list. Whether you’re upgrading or repairing, these models each come with their own unique touch.

Shurflo 2088-554-144 Fresh Water Pump, 12 Volts, 3.5 Gallons Per Minute, 45 Psi


  • Great Water Pressure and Very Versatile
  • Easy Installation and Extremely Efficient
  • High GPM Ensures Better Flow and Flushing During Use
  • Water Lines Hook up With Ease and Pump Runs Fast and Smooth


  • Very Few Buyers Report Bracket Holes Not Lining Up During Installation
  • Not as Quiet as E65 Model, But Still Better Than Average

This model is another crowd favorite and offers excellent pressure, high flow mechanics. This style is ready when you need it most and effectively carries water to your shower, toilet, or sink.

It’s lightweight and convenient design makes installation headache free and ideal for those who need a secure fix of their existing model. It is thermally protected and created with a three chamber, positive displacement setup to pump 3.5 gallons per minute.

With this, the unit turns on naturally as pressure is reduced and stops when a preset pressure is reached. The suction lift is intended to self prime up to 9 feet and will pump on demand. No more worry about having to leave toilet water sitting or skipping showers.

Bottom Line

The bottom line with the SHURFLO, the 2088-554-144 is that this model is user friendly, dependable, and will hold great pressure. While it may not be as quiet as some, SHURFLO still does an outstanding job at delivering high quality products at an affordable price.

  • The Pressure is Not Enough for a Larger Area

What Recent Buyers Report

Buyers are mostly content with this motor because it is a good option. It is compatible to be used with agricultural herbicide and is also reported to be durable. However, people do have some trouble getting additional parts for it, which are costly.

Why it Stands Out to Us

The material that is used for the body of the motor, polypropylene, makes it work for longer times and is long lasting. What is more, the diaphragm and the Viton valves make sure that it can be used for various purposes.

Who Would Use This Most?

Suitable for use for people who want a water pump on their RV, this product can be easily used by people for various purposes. It provides an acceptable pressure with very little noise so you will not be disturbing anyone when traveling on your RV.

What Could be Improved and Why?

Although many features in this water pump are commendable, the prices of the fitting parts need to be manageable because people do not like the extra cost. Another thing that needs improvement is the pressure provided by it. More pressure would have been better.

Bottom Line

A nice and durable product to use, the SHURflo water pump can be relied on to be used for heavy-duty functions, and you will not have to worry about its durability. However, you will have to invest a bit to get the best.

People have been using this water pump for many different purposes, and mostly all of them seem happy with it. Whether it is spraying insecticides, water, sanitizer, or anything else, it does not seem to pose a problem.

Why it Stands Out to Us

The small size as well as the light weight of this unit are features that are not usually found in such products, so this amazing addition sure is worth looking out for. You can easily use this for agricultural purposes among many others.

Who Would Use This Most?

Being compact and easy to carry around, this becomes a perfect product for people who are usually traveling on their RV. They will not have to think about getting different things for the same purpose, so that is an added cost-cutting advantage.

What Could be Improved and Why?

Bringing you a great product with the Amarine water pressure pump, it also has a few drawbacks that could be worked on. The pressure provided by the pump is low if you are looking for a pump to serve you for a longer time, and that is something manufacturers could work on.

Bottom Line

This water pump allows you to stay relaxed if you want a pump to take with you on your adventures. The compact size makes it portable and keeps giving you comfort with its automatic pressure switch.

Best Flojet Water Pump:

  • Higher Priced than Competing Models

The next item we have, is the Flojet 04406043A quiet quad water pump system. This self priming unit pumps 3.3 GPM and is backed by an excellent 2-year limited warranty.

While it is on the pricier side, this works great and is the perfect product to swap out that loud, outdated OEM model.  

Bottom Line

The bottom line with this model is that it it will surely get the job done and performs well. The most noticeable drawback we found that’s worth mentioning is that it’s designed for intermittent duty only, which is not noted on Amazon. Aside from this, many recent buyers report that the pump’s pressure holds well and it’s backed by a great warranty.

What Recent Buyers Report

People who have purchased this unit have been satisfied with the amount of work they can get done from a single pump. Giving them appropriate water pressure, this is also known for surviving in extreme weather.

Why it Stands Out to Us

The fact that it is able to self-prime is an amazing advantage of this water pump. What is more, it also has a built-in bypass for a lesser amount of pulsation. You also will not need an accumulator tank with it.

Who Would Use This Most?

Its durable and convenient design makes it an impeccable choice if you want a unit to take with you on your RV. Using the port fittings and the soft mounting, you can ensure a secure space for the product.

What Could be Improved and Why?

One thing that can surely be worked on is the noise that is made when it vibrates. This may be disturbing for people who are in an enclosed space on their RV. The depth from where the water is drawn is also less.

Bottom Line

This unit seems to be a better option than many, so you can be sure of the fact that it will stay by your side when you need water for various purposes like washing or if you want to store some for later use.

  • Considered a Bit Noisy by Some When Cycling, but Quieter than OEM Models

Another SHURFLO model to make our list is the 4048153E75. Designed for extreme performance and smooth delivery, this product is built for reliability and assurance that your water will reach you at a moments notice.

It’s high end construction of a one-piece diaphragm system is intended to operate and run dry without signs of damage over a long period of time. Additionally, this electric model is designed to mount in any position and hook up with ease.

It is set to pump at 4 gallons per minute and cycle at 55 PSI. SHURFLO continuously strives to deliver top of the line products and this is another fantastic example.

Bottom Line 

Overall, the bottom line with the SHURFLO 4048153E75 is that this is a powerhouse and ideal for those looking to upgrade their existing model or replace a broken one. The only drawback we seemed to find is that when cycling, some buyers report that it can be loud at times; however, this is expected with a 4 GPM capacity.

Why it Stands Out to Us

Quite a few factors allow this product to be truly one of its kind. First of all, it has a low price, so that means you get more than what is expected. Also, the adjustable pressure switch allows you to forget your worries about it.

Who Would Use This Most?

Living out of the excellent comfort of your home is a challenge but not for people who have this water pump with them because it gives them the freedom to enjoy the luxury of water whenever and wherever they want.

What Could be Improved and Why?

Among its many plus points, this could use some improvement in terms of sealing the product. It should not come in a padded envelope, and it should also not leak from the sides because it will lose its purpose otherwise.

Bottom Line

The Marine water pump is a good choice to buy, it surely gives you more features than what you would expect from something of its size. The automatic pressure switch gives it an edge among others.

People Also Ask

Owning a water pump, and that too for your RV is a major plus point. When you are going around in the RV, you never know the reason you might need a good water supply. However, one must also know the various nuances you have to take into consideration before you choose the final unit for your RV.

How to Prime an RV Water Pump?

The first thing you do is check the tank. The level of water should not be low, so fill it up. Next, you will have to see if the faucets are completely open. As you switch the pump on, it should be primed.

How Does an RV Water Pump Work?

The basic purpose of a pump is to draw water from a tank. It will make sure that it is able to send water to the shower, sinks, and toilets. The pressure switch on the unit controls the flow when you turn on the faucet.

How Long Do RV Water Pumps Last?

If you have invested in a good water pump, it is destined to last for about ten years at least. If you take enough care of it – protecting it from cold, corrosion or mineral build-up – it will always stay by your side.

How Do You Tell if Your Water Pump Goes Bad?

One of the few signs that show you that your unit is going bad is constant leakage. It might also be overheating or giving out steam. These are the important indicators of knowing that it is time you change or repair the unit you are using.

Do RV Water Pumps Run Off Battery?

You can have a water pump that has a set of batteries installed, and this will power it up. However, the power that you will get from these batteries will not be as much. The reason behind this is that they will run out or drain out quickly if you use a high-powered unit.

Is it Bad to Leave Water Pumps on in Your RV?

If your RV water pump is connected to a fresh water supply, there is no harm in leaving it on. The reason for this is that the unit will only come into action when you switch on the water supply for anything inside. If not, the water pump will not be pumping any water, so it will not be wasted.

How Do I Keep My RV’s Water Pump From Freezing?

Since water pumps are not adapted to cold temperatures, one thing you can do to avoid the pump from freezing is wrapping the hose. When you insulate it, you automatically protect it from freezing. You can also insulate the valves and make sure that any frozen hoses are thawed.
