Photo: Shurflo
- Flow Rate: 3 GPM
- Pressure: 55 PSI

You get a self-priming pump with three chambers and suction lift up to 9 feet. It can also run dry without problems, and Flojet backs it with a 2-year warranty.
The package lacks a filter and it's also worth noting that while this water pump gets made using corrosion-resistant materials, it's in no way a substitute for real marine or salt-water pumps. It will handle a little salty water, but it wouldn't last long in such conditions.
Pros:
Cons:
5. Remco 55Aquajet-ARV – Variable Speed Adjusts to Water Pressure Needs
Photo: Remco
- Flow Rate: 5.3 GPM
- Pressure: 65 PSI

- Flow Rate: 1.2 GPM
- Pressure: 35 PSI
- Power: 2.7 Amps
With a flow rate of just 1.2 GPM and a shut-off pressure of 35 PSI, this is without a doubt, one of the smallest RV water pump in this review.

It also measures only 6.5 inches in length and weighs a little over 1 pound. Still, it's self-priming and can deliver suction heights up to 4 feet.
On the other hand, the package includes no accessories and this pump is not ideal for larger RVs.

Photo: Amarine-Made
- Flow Rate: 1.1 GPM
- Pressure: 35 PSI
- Power: 2.7 Amps
Here comes the smallest and the quietest RV water pump in this review. Measuring less than seven inches in length, it delivers only 1.1 gallons of water per minute, which is perfect for many small RVs, campers, and boats.
This pump's cut-off pressure is 35 PSI and it is self-priming to about 4 feet of head. It can also run dry without damage and it features thermal overload protection.
Another important feature of this pump is its very quiet operation. It draws little current to work and includes soft rubber mounts for quieter operation.
The package includes no accessories and you should note that it's too small for most medium to large RVs, but if you're looking for an energy-saving pump or if low noise is important to you, and low water flow isn't a problem, then take a closer look at this offer.

How to Buy the Best RV Water Pump
Photo: gonewiththewynns.com
RV water pumps are unique devices with a specific purpose, and this makes it necessary to learn a little about them if you want to make the right choice.
Following are important features and factors to consider when you're picking an RV water pump for your camper.
1. Flow Rate
A pump's flow rate is a method of measuring how much work it does in a given period, and since the pump's job is to pump water, the amount of water that it pumps in a given period is its flow rate.
The flow rate for RV water pumps is usually given in GPM, which stands for Gallons Per Minute. Larger, residential pumps can also get measured in GPH (Gallons Per Hour), but for RV purposes, GPM is enough.
A flow rate of about 3 or 3.5 GPM is often enough for most RV purposes. If you're changing an old pump, then it's easy to look on its label for the right flow rate and then, stick to it.
You don't want to get a pump that's either too powerful or too weak, as it may either cause problems in your camper's plumbing or drain the battery.
2. Pressure
Water pressure gets measured in PSI, which stands for Pounds per Square Inch. It's closely related to flow rate but it has a double function when it comes to RV water pumps.
The first function is that a higher water pressure means an increased flow rate, and this lets you get enough water around your camper. A range of 60 to 75 PSI is ideal for most rigs.
The second function is with the on-demand feature of RV water pumps. They measure the pressure in the pipe and will stop pumping if it's higher than a given threshold, such as when you close the faucet.
The pump will also resume pumping once the pressure falls below another threshold. So, if you open a faucet, the pressure falls and the pump switches back on.
3. Amps/Power
Most RV water pumps run on the 12 Volts power supply that you find in automobiles. So, the difference between the models here is their current consumption.
Current gets measured in Amps and when multiplied by 12 Volts will give you the power consumption of the pump in Watts.
While most RV water pumps have their power consumption in acceptable ranges, you may want to opt for a lower-powered version if you've got power consumption issues.
4. Noise Level
All RV water pumps will produce a certain level of noise, but they are usually within tolerable limits. This makes it unnecessary to worry about the noise.
If, however, you end up with a very noisy RV water pump that you can't bear, then it's probably broken. If it's still under warranty, then it's best to get it replaced.
5. Energy Consumption
You also need to keep an eye on the pump's energy consumption because most RVs only have so much energy to offer. So, what you need is an energy-efficient pump that delivers as much water as possible, while using as little electricity as possible.
Sine nearly all RV water pumps run on 12 Volts, you'll just need to look at how much current the pump draws, which is given in Amps or amperes, then compare it to its flow rate, which is given in GPM.
6. Warranty & Price
A good product usually comes with a good warranty and often at a higher cost, as well. So, it's left for you here to choose your balance between price and quality.
RV Water Pump Troubleshooting & Fixes

Making repairs is an inevitable part of RVing and something that you too will have to do at one point. So, whether you're new to RVing or you've been on the road for all your life, you'll need this guide to help you fix your water pump when it starts misbehaving,
Remember, however, that when your water pump breaks down beyond repair, it might be a good time to replace it with a new one.
Following are the most frequent scenarios and questions, followed by their troubleshooting and fixing guides.
Question 1. I can hear the pump working but water isn't flowing, what do I do?
Ans: There are many reasons for such a situation and it can include a low water level in the tank, an air leak in the suction line, a punctured pump diaphragm, or a worn-out pump impeller.
You'll need to troubleshoot the system to find out which of the reasons is responsible. First, check all the water lines to make sure they're not clogged, then the hose clamps, drive belt, and other parts of the pump.

Question 2. The pump doesn't run at all.
Ans: If you open a faucet or the shower and the pump doesn't go on at all, it could be a result of either a bad pump motor or issues with the electrical system and wiring.
Check to make sure that the master switch is actually on. Also, make sure that there's no blown fuse and that the battery has enough charge to power the pump. Then check the overall wiring of the pump to make sure that nothing is loose.
Question 3. Why does the water pump cycle on and off with closed faucets?
Ans: When this happens, then the pressure switch has either become defective or there's a leak somewhere in the system.
To solve the problem, check that there are no water leaks. Check the faucets, toilet valves, internal pump leak, and other parts of the plumbing lines that could possibly be leaking.
Question 4. Why does the water from the pump sputter?
Ans: Sputtering water means one thing and that's air. You'll need to find the source of air in the air and get rid of it. There could be an air leak in the suction side, or in the lines somewhere. You'll need to repair any leaks and bleed any air in the lines.
Question 5. My pump is too loud, what's the problem?
Ans: Worn out parts and loose mounting bolts are often responsible for loud RV water pumps. The pump's intake line could also be restricted in one way or the other.
Check the pump and tighten all loose bolts and drive pulleys. Make sure that the pump is properly installed according to the manufacturer's instructions and replace any worn out bushings with new ones.
