Motorized, self-priming pump creates a consistent flow of fresh water to your RV or camper. Works as a direct replacement for a 12-volt pump. The quiet pump has a check valve to prevent backflow and a thermal breaker to prevent overheating.

Notes:
This motorized pump can be used as a direct replacement for any OEM RV or marine pump and lets you supply a smooth, consistent flow to the fresh water system in your RV, camper, or boat. The diaphragm-style pump has a self-priming design. The sealed, flexible diaphragm creates a vacuum that draws in the water, allowing the pump to self-prime. This design eliminates air pockets in the pipeline - also known as air binding - for a steady, uninterrupted stream of water to your faucet or other fresh water source. It has the ability to prime up to 6' vertically and 30' horizontally. The pump also features an internal check valve that prevents backflow contamination of your clean water supply.
The pump has been thoroughly freeze and thaw tested for up to 5 two-hour cycles, and it was tested with a higher pressure at shutoff than other water pumps.
The heavy-duty motor operates quietly without any disturbances and features ball bearings that enable it to have a long life. It doesn't have a rotating seal that will burn up, allowing it the ability to run dry without causing any damage.
The motor also has an integrated thermal breaker that interrupts operation when the motor becomes too hot in order to protect it from overheating. When the temperature of the motor drops, the breaker automatically resets.
This enclosed, water-resistant pump has sealed switches that keep moisture from getting in. The electrocoating finish withstands the effects of rain, snow, and other elements, preventing rust and ensuring long-lasting durability.
This water pump can be bolted down in multiple locations and positions. It can be installed above, below, or at the same level as the water tank, as long as the location is dry and easily accessible for maintenance. Mounting hardware is not included.
Once the pump is bolted down, insert the strainer on the inlet side. This strainer prevents bugs and debris from entering the pump. Then with the included swivel fittings, attach high-pressure hoses to the strainer and the outlet port for a tapered, watertight seal.
Finally, make your wire connections. The black wire is your live (or hotwire), the white wire is your neutral, and the green and yellow wire is your ground. Please note that a 15 amp switch and a 10 amp fuse (not included) are required.

Excellent
My devise work just fine
Easy site to navigate and tech info is good.
Replacement part thanks very much
Etrailer helped me find the correct pump replacement as my original was no longer available.
One full-timer year later and it’s still working.
Seems like the pressure switch was set too high,,,,,and the pump wouldn't shut off. Adjusted same,,,,and works perfectly
The pump is nice and quiet. Using the 1/2” ID hose that was installed, the swivel connectors is a problem with cinch clips. The base of the connector is wider than the old one and 1/2” cinch clip will not go on. Tried 5/8” and it won’t cinch tight. I had taken the old hose runs apart to replace new hose while I was at it. Had to use the old connectors.
We don't use the onboard storage tank every trip, but so far when we do, the pump has been working reliably.

The water pump is still working fine albeit that we use it for just two boondocking trips a year about one week each.
I love the customer service and follow up I get from this company.

Still working great!
Appreciate that etrailer warranted the first flow max RV pump I ordered: it was a disfunctional pump (leaked). I did have to pay additional $[XX] for return shipping of that original defective pump. However, the replacement 2nd pump they sent is working great (have had it installed a few days now) and is not leaking like the first one did. Their service at etrailer is a 5 star but the Flow Max Pump is only a 4 star for now. If it passes the test of time (atleast 3-5 years) then maybe it will get an additional star? Original pump lasted nearly 20 years before it went belly up.
The pump was extremely quiet and preformed flawless. Highly recommend it.
Great product delivered on time.
Using this as a spare for whenever I will need to replace my current pump. So I haven't installed it yet but assuming all will be perfect when I do.
Easy to install even for novice like me. Has worked well.
Have not used it yet, just bought for a spare.
Perfect, more than pleased with CSR assistance and product.
Joshua was a pleasure to work with and our water pump arrived promptly!! We've got etrailer on speed dial now!
Haven't installed it yet but the package seems complete
Works great. Easy installation. The flow max water pump mounted in the same holes as my old SHURflo 2088 did. I ended up using my SHURflo strainer on the intake of the pump because it was shorter than the new included strainer. My flex inlet and discharge lines run through holes which make them hard to move.
Works as intended
