Best On A Budget

Seaflo RV Water Pump

Seaflo 12V DC 1.2 GPM 35 PSI 21-Series Diaphragm Water Pressure Pump for Caravan/RV/Boat/Marine

The Seaflo RV Water Pump is another great choice for anyone who has a small RV or one without a luxury shower. It’s durable, affordable, and will give you enough pressure for everything to work fine.

The pump is self-priming and comes on automatically when you turn the taps on and off. So no hassles there. It also has an excellent build and will last for years thanks to the design and the durable materials used to make it.

Some people have used this water pump for 4 years and had it work again after they forgot to winterize it, so that’s some tough going.

The pump pushes the water out at 1.2 gpm which is enough for a small RV or a normal RV with a basic shower. If you have a large RV or a luxury shower and want so solid pressure, you’ll want a pump that can do around 3.5 GPM.

This RV water pump is also quiet while it runs, but it’s not silent, there is still some noise. It’s also extremely affordable at around the $20 mark, and for the quality, it’s hard to beat.

Pros

  • Very affordable
  • Light and small for slotting into tight spots
  • Self-priming for ease of use
  • Quiet while in operation
  • Auto on and off when you open the taps
  • Long-lasting durability

It’s a self-priming RV water pump and it’s made from quality materials that don’t corrode, ensuring you have minimal maintenance to do. The pump also has a great suction lift of up to 7 ft, and others have used it to pump 17 ft horizontally and 4 ft up in their RVs without any worries.

The installation is very easy as the pump uses zero leak quick slide connectors and you can find a lot of adapters to match your current setup. It’ll automatically come on when there is 1.5 bar of pressure in the system, giving you instant water pressure when you open a tap or shower.

The hook-up is easy, and once you connect it to your 12-volt system, just turn it on and the pressure switch setting of 3.4 bar will have it turn on automatically when you run your taps or your shower.

The Shurflo Fresh Water RV Pump is another great choice for your RV, but again, it’s pretty noisy. The instructions even say don’t mount it in your bedroom, but for some, that’s where the water tank is.

This is a self-priming pump for ease of use, and it’s made from durable materials to guarantee low maintenance and hassle-free long term pumping experience. Once hooked up to your 12-volt system, the pump automatically kicks in at around 5 Psi to deliver water all around your RV.

The Bayite Fresh Water RV Pump is about as affordable as an RV pump can get. You can buy it for less than $20, but it is cheap for a reason. Most people find this pump doesn’t last very long, but with some tweaks, they get it working fine.

If you know your water pumps, this might be a very cost-effective RV pump, and if you don’t, then it’s worth owning as spare as it’s so affordable.

The fresh water pump is self-priming and is made from durable materials that handle corrosion well. Installing it is simple, but it’s not water-resistant, so you’ll need to make sure it’s installed in a dry area away from any water or weather.

Once installed it’ll click on automatically at 35 Psi and click off at 80 Psi. Some people have had issues with it trying to click off and then it turning on at higher Psis than 35. When in operation the water pump isn’t loud, but it’s not quite quiet either.

You’ll get about 1.05 gallons per minute out of this 12 volt water pump which is a bit low but might work for some smaller RVs. There also aren’t too many RV hot water tanks that will click on at this flow rate, so be sure cot check yours before you buy this water pump.

Remco AQUAJET Rv Series Water Pump

Remco (55-AQUAJET ARV Aquajet RV Series Water Pump

The Remco AQUAJET Rv Series Water Pump is a serious pump and it best suited to larger RVs and motor homes. This is because its pressure output is high and if put in a small RV it can bust valves and pipes.

When in operation, the 12 volt water pump is quieter than most and will push out 3.5 gallons per minute, which is ideal for use in an RV. The RV water pump is quite expensive though, and almost 8 times the price of some noisier pumps, so it is a bit of an investment.

This is another self-priming water pump that is well made, and built with durable materials that are corrosion resistant. The pump will turn on and off automatically when you open and close your taps, and when it runs, it’s quieter than most. It’s not quiet though, and you will still get some noise when using it.

The water pump pushes the water out at 1,5 gallons per minute which is a bit lower than others that can manage 3,5 gallons per minute. It has a suction lift of 4ft and you should still get good water pressure in your RV’s shower with it, as long as it’s not too big.

1.5 gallons per minute is also enough for most tankless RV water heaters to click on with, so in essence, this pump will be fine, but it’s the personal choice over the pressure that you need to make.

What To Look For In An RV Water Pump

Matching You RV’s Plumbing System

When buying an RV water pump, it has to match the existing system and this comes down to knowing the pump’s suction lift, GPM, and Psi and then matching it to your RV.

A suction lift describes how much distance the pump can pull water over, letting you know the max distance from the tank it can be at. Some have 4ft some have9 ft suction lifts, and you should know the pipe distance between your RV’s water tank and where the pump will sit in order to match them.

Psi stands for pounds per square inch of pressure and if you put a pump into your RV that has too much Psi for the system, you’re going to blow valves and damage the plumbing. Most RVs work at 55 Psi and up to 80, and your pump should off automatically before hitting the maximum the system can hold.

Gallons per minute is about what comes out of your tap. If you have a small RV, 1.2 gallons per minute is ok, if you have a large one with a luxury shower, then you might want to go up to 3.5 GPM. You should also consider your tankless Rv water heater, as it’ll click on at a minimum GPM, so for it to work, your water pump will need to match it.

Noise

RV water pumps can make a lot of noise but some are quieter than others, but they are also more expensive. The water pump will only make noise when you’re running a tap or having a shower, so it won’t be on all the time. If you want a pump that makes as little noise as possible, look for a 5 chamber design, as this reduces the vibrations when compared to a 3 chamber.

You can also add a different mounting to the RV water pump that’ll absorb the vibrations and recuse the sound too. Most pumps won’t come with one as standard but you can go buy one separately if you want to ensure you can have a shower in peace.

Size & Installation

Before buying an RV water pump, check out where the pump will go and see how much space it is available. The last thing you want is to order a pump and no fit when it comes to installing it. You should also check out if the pump comes with the parts you need for your installation.

Most pumps do include everything you need for a generic installation, but you may have to buy adapters depending on your RV’s plumbing connections.
