What are the two main jobs of the best RV water pumps?

Knowing the main jobs of water-pumps will allow you to understand their importance and how they can do the wonder for your travels.

Job #1: Provide pressured water from your rig tank. This is the number one job of your RV water pump. Your RV comes with built-in water tanks where they can store their water. These tanks are commonly found in the base of your trailer or motorhome. Checking these tanks, you will find three different storages for the water. There’s a tank for fresh water, gray or used water, and black or wastewater. With this RV water pump, you will have the supply of water from the kitchen and bathroom faucets, and you can keep the water flow of the shower and toilet. 

Job #2: Provides a certain amount of water per minute. The second job of an RV water pump will depend on its capacity and your needs for water supply. Some common trailers or campers are using pumps that can make 3.5 gallons of water per minute while the larger motorhomes are using pumps that can produce around 5.3 gallons of water every minute so it can meet their needs. The produced gallons of water every minute is equated to the pressure per square inch or also called as psi.

What are the things that you should look for when buying a new RV water pump?

  1. Water specifications. Every RV water pump comes with an RV manual that you can study so you will know how to install and use the pump properly. This manual will also reflect the water specifications of your new RV water pump. If you cannot find the manual, then you need to call a service center or a dealer that is experienced and knowledgeable about the brand of your pump.
  1. The gallons of water it can produce every minute. This is very vital when it comes to buying a new RV water pump since you would want a pump that can supply your needed amount of water while you are traveling. You can easily find the maximum number of gallons per minute that a pump can produce so you can determine the right pump for your RV.
  1. Recommended water pressure for your RV. You should find an RV water pump that can provide the recommended water pressure for your RV. Don’t go too much with the water pressure when your RV does not need it because it can cause some trouble when you try to use it for the first time. 
  1. Determine the dimension of your current RV water pump. If you are currently using a water pump, check out its dimension so it will be easier to find the new water pump for RV.

Different Benefits of RV Water Pump

Since we are talking about the RV water pumps and their jobs, we need to know about the different benefits of these products. With these benefits, you will have a better idea of why you need the best RV water pump.

Consistent water supply – Can you imagine traveling in an Rv without a reliable supply of water? You may feel uncomfortable with so many things while you are taking the road. This problem can be solved with a reliable water pump. With this pump, you don’t have to worry about going out and looking for water supply so you can do your hygiene and other necessary duties that will require water. Simply fill up your tanks with enough water, and your RV water pump will make sure that your tap, shower, and toilet will never run out of water.

Save on space – RV water pumps are smaller and lighter than the common water pumps that you can find around. You may also get a water pump with high pressure without sacrificing a big space in your RV.

Energy Efficient – You don’t have to worry about electricity or water bills with an RV water pump since these gadgets can run efficiently using your RV’s battery. While some pumps will require electricity, so they do their jobs well, they don’t go beyond 24 volts, which means they still won’t hurt your electricity bills.

Easy to Install – If you have seen some pumping units that come with very complicated steps to install it, you will find it amazing why RV water pumps don’t work the same when it comes to the installation process. With a simple look at the pump manual and a brief reading and understanding of the steps, it is very easy to connect the pump so you can get started with pumping water to your shower, faucet, tap, and toilet.

Key Features of a Camper Water Pump


With the water pump for RV, you will have two options for their voltage – the 12 volts and 24 volts. The right volt for your RV will depend on your needed amount of water and your RV’s size. You just have to keep in mind that a pump with a lower voltage is more manageable since it consumes less power from the system. While the higher voltage can do a higher performance, but it can drain the battery or generator of your RV.


When determining the right pump water pressure for your RV, the most important thing that you need to consider is the need for your RV. To determine the ideal GPM for your recreational vehicle, you should review your RV owner’s manual. For a tight budget or small to medium-sized RV, choose a water pump that can produce at least 1 gallon of water per minute. But for larger RVs that require a greater amount of water, the recommended water pump can make 5 gallons per minute.

Automated Pump Cycle

To determine if you have a good pump, you should check if the pumping automatically stops once the preset values are reached. The pumping must also start automatically if the water pressure goes below the preset value. With an automated pump cycle, you will have a seamless operation that will never require constant management from you or any of your company. The automatic feature will also prevent any possible plumbing system problems that may occur because of running the pump continually.

Noise Level

Not all RV water pump models do the work quietly. Some pumps can be loud when running, and this is the last thing that you want to hear while taking a nap inside your RV. If you don’t want to deal with this hassle and discomfort, you should find a water pump that can run without making any noise. You will find many of them in the market, and they don’t have to be the most expensive pump. 

Self Priming

Unlike those traditional water pumps that you can find at home or any other residence, an RV water pump was designed to receive water from a limited water source. With the self-priming feature, your pump can lift water from the tube, although the water supply is running low. Another thing is you don’t have to worry about damaging your water pump when it is running dry.

Since you have some ideas about the RV fresh water pump and what it does for your RV, it’s time to know some of the best RV water pumps available in the market. This will help you in finding the best water pump for your RV.

How long does RV water-pumps last?

The lifespan of your RV water-pump will depend on how you use it and if you are doing the proper maintenance for your pump. When you purchase a new RV pump, you will find a water-pump manual that you can study well so you will know the proper maintenance of the product. If there is a guide provided, you need to follow it so your water-pump can last longer.

Caravan water pumps come with a filter, and this filter is important to block the debris in the water tank and prevent them from getting into the water pump’s internal valves. As part of the maintenance of the water pump, you need to remove and clean the filter found on the intake side of the pump. With most water-pumps, these filters can be removed so you can clean the screen separately. For those pumps that don’t have a filter, you should buy a filter that is appropriate to the model of your water pump. If there is no room to fit the appropriate filter, then inline filters can also be used.

Every self-contained motorhome needs a water pump so that hookups can be provided. However, we are also aware that the best RV water pumps are frequently used since they stay in full-hookup RV parks. Yet we cannot dismiss the fact that we need to maintain every RV pump so it can be used anytime when you are game for a long road trip or camping.

Never overlook the regular maintenance of your water pump. Don’t make yourself one of those campers who are following the axiom “out of sight, out of mind.” Be responsible for your water pump. Do an annual maintenance check and make corrections if needed so you can ensure that your water pump can perfectly keep the water system from flowing.

This brand is the best in the category, and it is one of the most reliable water-pumps. The RV community loves Shurflo because of its commitment to deliver and perform.

  • One of the top reasons why the RVing community is preferring the Shurflo pump is because of its price. While you may find Shurflo models competitive and top-performing, they are fairly priced. It can exceed everyone’s expectations since the water-pumps are working above standard.
  • The 2-year limited warranty, self-priming, built-in check valve, and internal bypass low cycling are additional reasons why you should go with the Shurflo water pump.

What is the most efficient RV water pump?

The Flojet 03526-144A Water System is the most energy-efficient water pump for RV. This pump can deliver consistent water flow to your RV’s shower, toilet, and taps. It comes with three chambers for optimal water flow, and the maximum capacity is 50 PSI. This Flojet water-pump can deliver a consistent water pressure of 2.9 gallons per minute.

How can I make my RV water pump quieter?

Not all RV water-pumps can do the work quietly, and if you have a water pump that is too noisy for you, don’t worry because there is a solution to that. Get a Water Pump Silencer Kit and connect it directly to your water-pump for RV. With the help of this kit, it can minimize or even eliminate the Jack Hammering noise. The kit comes with soft supply hoses that serve as a cushion to damper the vibrations passed to the harder water supply lines. If you are part of the RB community, you will know that many campers have successfully used this kit.

Are high flow RV water pumps worth it?

Yes, a high flow water-pump can indeed help with reducing the cooling temperature, but it does not mean that it can provide a solution with the overheating issues. With a high flow water-pump or high volume water-pump, you can increase the water flow, which will help in moving the coolant faster.

Generally speaking, higher flow and higher pressure can help with the cooling system. Since the higher pressure is raising the fluid’s boiling point, it decreases the chances of vapor forming in the coolant. With this condition, better cooling, cooler valves, rounder cylinders, and more other improvements can be achieved. The higher flow rate of the water will increase the heat rejection rate from the radiator.

With all those benefits mentioned above, you may also question if these high-performance pumps can help with overheating issues. But according to some experts, if the current problem is not related to coolant, then an upgrade with the water-pump will not deliver a significant improvement with the performance. For instance, if the concern is about a poor fan setup, the presence of a better water-pump will not solve the problem.

With these thoughts, we can say that high flow water-pumps may or may not be worth it. Depending on your problem or your needs, you should evaluate well before you go on with this type of water pump.

Best RV Water Pump Conclusion

With all those options that you can see in the market, finding the best RV water pump for you can be hard. The process will never be simple since the water-pump is important for your travel and camping. You will have to find the right product for your RV. You are not alone with all these struggles because the RVing community has been there in your place. The important part about this search is you know your RV well, and you know your needs as well. With these factors, you are ready to do the shopping for the best water-pump for RV.
