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.

Hi! The Flow Max RV Fresh Water Pump we bought a year ago was easy to install. It was a direct replacement for the leaky, antiquated pump it replaced. After a year it still works even after the water froze. Thank you for an excellent product.
The water pump supplied by my RV's OEM developed a leak and was no longer available. In searching for a replacement, I found etrailer.com offering a pump with similar specifications at a very reasonable price. The pump arrived shortly after placing the order with complete instructions for installation which subsequently was very smoothly and successfully accomplished. The new pump is even quieter than the original and I am very pleased with it.
Easy to install even for novice like me. Has worked well.
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.
Great product delivered on time.
The pump was extremely quiet and preformed flawless. Highly recommend it.
Everything pertaining to the pump was good I just wish they would have taped the box shut things could have been missing or lost
I love the customer service and follow up I get from this company.
Everything as described.
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.
Couldn't have been easier to swap out this new water pump for the old one in my 1996 Jamboree Sport without a hitch. Superior pumping performance than the old burnt out Sure flo 2088-403-144 that it replaced. I chose this pump because the 45psi pressure matched my old one and is what my system was designed to operate at most efficiently by it's engineers. The flow rate of this pump is slightly higher but seems the same in actual use. It draws slightly less amperage which is always nice as the battery lasts a little longer. This unit is almost silent in comparison to the old pump yet it keeps the system pumped up better. It doesn't even run constantly when I wash my hands like the old one did. It bolted right up and connected to the old hardware although I actually cut off the old brass 90º screw on connecters and installed a new pex 90º connecters because the 24 year old brass fittings were so corroded and the seal so dried out and compressed that I didn't want to take chances on it leaking and wanted the best, most reliable install possible. I am extremely satisfied and very happy with the initial functionality and quality of this water pump and would recommend it to anybody with a 45psi motorhome water system. I am now ready for many more years of happy camping.

one year later and the water pump is working as good as the day I put it in. I am very happy with this quality product.
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.
Got it early !!!!
Plug and play install. It’s a little quieter than its failed predecessor
The Flow-Max was a shoe in for the old Shurflo pump which failed after eight years. I was very happy with that and it arrived in a nick of time. It also is much quieter the the Shurflo.
Seems like the pressure switch was set too high,,,,,and the pump wouldn't shut off. Adjusted same,,,,and works perfectly
Prompt and great service
Came early, excited to get it in.
Thank you
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.

Still working fine one year later.
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.
This pump looks/feels more durable than the original pump that came with my camper. It mounts to the exact same screw holes in the floor and wiring is very simple. I like the new screen filter too. One year in service and I'm very happy with its performance.
So far, so good! Easy installation after I realized I needed to reinstall the rubber washers between the fittings and the new pump. Then two wire nuts (self provided) and voila, all done.
Great product! The water pump works great! Thanks for the great service!!!
PSI only slightly better in the shower than OEM pump it replaced. However, better PSI at the kitchen sink.
I went with Sharkbite fittings to solve replacement fitting leaks.
Very good product. Installation was simple and a perfect fit.
