Best RV Water Pumps: Improve Your RV’s Water Flow System

The SHURFLO Revolution water pump gets love from the RV community due to its reliability and the commitment of the company to deliver high-performance units. The pump performs at 115 volts of power usage. It features an internal bypass and a one-piece diaphragm that makes it suitable for almost all plumbing systems. In addition, the pump can be mounted in any position.

The pump features thermal protection for damage prevention and user safety. SHURFLO makes a somewhat quiet RV water pump; it produces minimal vibrations thanks to the manufacturer’s Flow Reaction technology that reduces noise but increases efficiency. The pump has a smooth-running pump cycle with zero rapid cycling and a system that stops automatically when a preset pressure has been reached.

The main drawback of this product is that it pumps fewer gallons per minute than other high-end products in its category. Also, it’s a replacement pump and doesn’t come with hook-up equipment, which you would have to purchase separately.

The Seaflo 21-series pump is a budget-friendly pump designed for quite a wide range of applications. This includes filtration, dispensing, spraying, and liquid transfer. It has an average capacity output of 1.2 gallons per minute and a 35 PSI pressure that makes the unit quite efficient for mid-size and small RVs.

The pump has a self-priming feature and can run dry and lift water from a limited water supply. Soft rubber mounts make this product easy to install, and the entire unit is protected from thermal overload. It also has an automatic switch that controls the pump by turning it off when the preset values for pressure are achieved. In addition, the product is backed by a four-year warranty.

One drawback is that it’s not recommended for heavy-duty use. The unit is also a cheap product and has a shorter lifespan in comparison to higher-priced options. However, with light use, the pump can last longer. You may also have a hard time getting in touch with Seaflo for warranty-related issues.

We couldn’t fail to mention the Flojet 03526-144A as it is one of the most energy-efficient water pumps for RVs. The pump delivers constant water flow to your RV’s taps, shower, and toilet. It has a maximum capacity of 50 PSI and has three chambers for optimal water flow. Moreover, it delivers a consistent water pressure of 2.9 gallons per minute.  

The self-priming feature offers up to 9 feet of suction lift. It has a 12-volt DC motor that saves energy as it doesn’t draw a high current. The product comes fitted with a noise-absorbing mount that helps minimize any noise or vibrations from the system. In addition, the pump produces a smooth water flow and has a pulsation eliminator that enables the pump to work independently without an accumulator tank.

A drawback of the pump is that the noise-absorbing mount doesn’t fully eliminate noise but just reduces it to somewhat tolerable levels. It also has low water output and comes in a subpar package. Despite the setback, this model is ideal for mid-sized and large recreational vehicles. 

Here’s another SHURFLO pump that offers excellent water flow. With the power of 12 volts and the ability to pump 3.5 gallons of water per minute, the device is very efficient and reliable. It offers extraordinary performance and proves to be quite durable.

This is a three-chamber diaphragm pump with a thermally protected motor and check valve. It prevents reverse flow and turns off automatically at a consistent pressure of about 45 pounds per square inch. The motor even restarts automatically when the pressure drops to 15 PSI. Additionally, the pump comes with the necessary mounting hardware and installs it in a breeze.

What might bother you with this product, however, is the noise. The pump can be quite loud, so you'll most likely hear it working while in your RV. You might need to add foam pads or something else to muffle the sound. Another possible issue involves the mounting bracket. It sometimes needs modifications for a proper fit, although it mostly depends on the mounting area.

The Amarine Made water pump is a compact and reliable item that’s great for boats, campers, vans, and RVs. With a pressure of 35 pounds per square inch and a flow rate of 1.1 gallons per minute, it's rather convenient for small to medium applications. On top of that, it's energy-efficient and will save you some cash on electric bills.

One thing users like about this pump is the self-priming feature. The device shuts off automatically when the pressure is reached, and it’s able to run dry. It also has a built-in thermal protector and hose barb ports that measure 3/8 inches. There shouldn't be any overload or ignition issues, so you'll be able to use the pump for a while. Additionally, the pump works quietly and installs easily.

There are only a couple of drawbacks to keep in mind with this pump. First of all, it's quite small, and the volume of 1.1 gallons per minute might be unsuitable for those seeking a high water flow. Therefore, consider your application before making a purchase. Also, the pump doesn't have an on/off switch. You'll have to add it separately for more convenient use.

This impressive 12-volt water pump from Lippert Components offers 50 pounds per square inch and a flow rate of 3 gallons per minute. If you need a powerful performance and high flow rate, this might be a great option for you.

The pump is self-primed and very quiet. It doesn't vibrate and can even run dry without any issues. Another great thing about this pump is the heavy-duty motor. It's corrosion-resistant and proves to be very reliable and durable. All in all, the pump delivers a steady flow of water and is ideal for campers and RVs.

The pump might leak at the connections, however. It's not that noticeable and won't cause a huge issue, but it still might require some DIY work. Another part that might require some modifications is the mounting bracket. It may wear out rather quickly, so you'll probably need to reinforce it with some sturdy and durable materials.

The Flojet water pump is one of the first choices among RV enthusiasts. What makes it special and popular is its quality construction and reliable performance. The pump offers a 12-volt motor and a water flow of 3.2 gallons per minute. That makes it ideal for most applications, especially because of the low energy consumption.

The pump comes with a bypass valve that reduces water pulsation and makes it safer and more reliable. Overall, the pump performs without overheating and can run dry without getting damaged. It’s also easy to install. The package includes all the pieces necessary for installation, service, and maintenance.

One drawback with this pump is the noise. The device can be rather loud, and you might need to make some adjustments to reduce the annoying sounds. The other minor inconvenience might come from the included fittings. They are not of the best quality and might break easily.

If you're looking for a budget-friendly water pump for your RV, Camplux offers a great one. This particular model is suitable for a wide range of applications and is quite reliable. It gives you 35 pounds per square inch and a flow of 1.2 gallons per minute.

This is a self-priming pump that can be mounted above the tank. It can run dry without getting damaged and also turns on and off automatically, depending on the pressure. People use it for outdoor showers, sinks, water taps, and similar applications. You'll find the Camplux pump is well-built, reliable, and rather convenient for many purposes.

The main drawback of the pump is the low water flow. If you need a more powerful water pump for your RV, you might want to look for alternatives. Some find the Camplux pump too small and weak to deliver the necessary pressure. Therefore, consider your application before the purchase.
