This 12-volt water pump, built for RV use, but you can also use it for tiny homes and cabins. It does not consume much electrical power. It has a PSI (Pound-force per square inch) of 45 which pulls a max of 4.5 amps. 


This on-demand water pump is designed to cycle only when the pressure drops below the reading of 45 PSI. You will like that it has an increased flow rate at 3.5 gallons per minute. It also has a safety check valve to prevent reverse flow. 


Installation is easy, just release the pressure on the water lines. After which you need to unscrew the hoses from the old pump and attach the hoses to the new pump. Installing your own pump takes only 20 minutes and you will save lots of money on the labor costs.


Shurflow RV water pump may not be the quietest, but it is efficient. If you want to dampen the noise coming from the vibrations, you can use foam to wrap the water lines or get a silencing kit. The pump provides sufficient pressure and you can see it in the good water flow in the showerhead.


It protects the motor from overheating, by allowing a maximum water temperature of 130 degrees Fahrenheit. This is the compatible standard that most RV water heaters have. It has the following dimensions, 8 inches long by 4.45 inches tall by 4 inches wide. Do check if it will match the dimension of your existing water pump.



This is a great choice, as Shurflo has had a great reputation in the RV community for years. You can still see some of these models which are 20 years old and working well.

If you are running multiple faucets or have more users using the water at the same time, then Shurflo 4048153E75 is a great solution for you. It draws a maximum of 10 amp, which is higher than other regular pumps, to produce a pressure of 55 PSI. This is more powerful compared to other RV pumps, so do expect that it will produce more noise.


Shurflo 4048153E75 is less affordable compared to Shurflo 2088, due to its higher water flow rate. It runs at a higher flow rate of 4 gallons per minute. So if you are running the sink and the shower at the same time, you will find it produces more consistent pressure. 


Its high-powered pump helps to prevent backflow, to avoid plumbing nightmares. It uses Flow Reaction Technology to reduce cycling so that it only operates when the pressure drops below a certain level. This pump requires a standard 12-volt RV DC power supply. 



The pump can be mounted vertically or horizontally, depending on the setup of your RV trailer. It measures 6.25 inches long by 12.5 inches tall by 6.25 inches wide. It is a great choice if you have a large rig as it is a more powerful water pump.

  • Check Valve to prevent backflow
  • High flow rate
  • Can be mounted vertically or horizontally
  • Less affordable

If you are looking for a residential-like powered flow pump, Remco Aquajet is a great choice. It uses 10 amp of 12-volt electricity, which is a higher amperage draw. So you need to check if your RV electric system is designed to be able to cater to higher pressure in mind. 


Designed with Variable Speed RV water pump, it has a pressure sensor that can detect any drop in water pressure. It then automatically controls the motor speed to deliver constant water flow. It delivers 3.5 gallons per minute, thanks to its exclusive 5-valve design which helps deliver twice the flow. Standard RVs uses 3 or 4 chamber models.


This is different from Shurflo pumps which use a pressure switch that increases the noise level. Thus, you will find this pump very quiet as it does not cycle on and off. It auto shuts off at 75-85 psi.

Buying guide

Pump Flow Rate

Pump flow rate is measured by how many gallons of water it can pump per minute, GPM (Gallons Per Minute). It can range from 1 GPM to 5 GPM depending on the size of your camper.

Having a higher water pump flow rate allows you to have multiple faucets turned on at the same time, with a consistent stream of water. However, it requires more power to support a higher flow rate.

If you are using a small RV, then having a lower flow rate is sufficient. Do check the GPM which is optimal for your rig.

Water Pressure (PSI)

Water pressure is measured in PSI (Pounds per square inch). It is recommended to get a PSI between 40 and 70. Anything higher than that, you may be risking the possibility of water leaks. Do check what is the optimal PSI water pressure for your camper.

Pump Size

Depending on the space in your RV, not all water pumps sizes can fit.  Measure the dimensions of your current water pump upfront, before you buy your replacement.


Generally, pumps can be rather noisy due to the vibration caused by the motor to function. You can dampen the noise by using foam to wrap the water lines or get a silencing kit. Also, note that pumps with more diaphragm chambers are found to be quieter. 

Thermal Protection

To protect the motor from fire risk when it gets too hot, having thermal protection will help shut down the pump when it reaches a certain temperature limit.


There are 2 types of models, 12-volt and 24 volts. Lower voltage draws less power, and it is usually the preferred choice for most RVs. Generally, RV batteries power the 12-volt system, thus, you can run the pump on your RV battery without your generator running. But that will also mean the unit will not have high water pressure.

Higher voltage leads to higher performance, especially for heavy-duty tasks. The main drawback is that it may take up a lot of your RV power. This is usually the choice for larger RVs.

You need to choose a pump that will not overload the capacity of your RV power systems. Consider that you may be running other appliances together with your water pump.  This is to avoid blowing a fuse by drawing too much power on the same circuit.

Auto Switch Feature

Auto switch feature is found on most pumps. It will stop the pump when the present pressure rating is reached. Otherwise, it will continue to pump and risk the integrity of your plumbing systems. And if the pressure goes below the present levels, then it will start pumping again.

Benefits Of Getting A RV Water Pump

When you are traveling off-grid, having a reliable water supply will eliminate worry about searching for water. You can avoid dirty gas station bathrooms at all costs. It ensures your taps are never dry with constant running water, making your RV more livable. 

With the water pump running, it helps to pressurize the water lines of your RV when you are not connected to the water source. When turning on the faucet, your water pump will detect a pressure drop, and the pump will kick in. You will be able to enjoy a good shower with a boost in water pressure.  

Most RV pumps can run on RV’s battery, which draws very little energy. So you can use the pump even without the generator running. This helps save you on high electricity bills.

Some RVs have a valve where you can switch to use the water pump to draw antifreeze into the RV’s water lines so that the lines will not freeze and break during winter.

Our Verdict

You will not go wrong with any of these top-rated RV water pumps, as they are one of the best RV water pumps compared to other options you see on the market. 

If you still cannot decide and need a final recommendation, then we would recommend Shurflo 2088-554-144 Fresh Water Pump to elevate your camping experience. It is a reliable 12 volt water pump for an affordable price which comes with a great GPM flow rate plus thermal protection included. We highly recommend this pump as it is more affordable and highly popular among the RV community.
