Already had to replace it
The pump is quiet, has adequate pressure and comes with a strainer making it easy to check for contamination of foreign objects that may have entered the water tank. Installation was easy except for working in a cramped space.
My RV has made me a jack of all trades. Along with youtube. The video helped a lot except my unit is placed in the bathroom under the sink vs kitchen sink. A tight space with my legs almost in the shower out in the hall. The angles the human body can twist! After installation, I checked for leaks I had a small leak I tightened up the leaky fitting. The pump is a lot quieter for sure I have been very satisfied with all I have purchased from etrailer. From parts for my two vent fans to installed set of tire monitor system.
Much quieter than previous shurflo pump. Water pressure is excellent. The stream is a bit “pulsy” but that doesn’t bother us at all. The only reason I didn’t give 5 stars is because the pump is 2 days old. Last pump made it 12 years before it started leaking. If this lasts more than 2 years I’ll be happy to change it to a 5 star.

Excellent, pump has done great. Still quite and good pressure
Easy install for a dummy like me, works just fine
The pump is installed but something is wrong there’s no enough water pressure.
Ordered and received very quickly. Choose this pump to replace an existing unit that had lost a bit of power and lift. Installation was easy, took about 20 minutes as it was completely plug and play.
New unit delivers great pressure with a minimum of cycling.

Works great. Mounted it in the wet bay and use it to transfer water into the tank. Fast and relatively quiet
Works fine, doesn't surge like my last pump. I did add a bladder that helps too. Overall a reliable pump.
Easy to install,perfect replacement for my 1999 Shurflo 2088-404-144.Much quieter, too.Thank you for your help in making this purchase.
I just received the pump about an hour ago and this is a direct replacement for my Shurflo water pump. It took about 30 minutes to remove the old pump and install the new one. It runs quieter than the original pump and provides good pressure. So far, so good.
worked perfectly and bolted right in pl ace
The HydroMax RV pump was easy to install, it's reliable, and it works great!
The part was fine But I paid Extra on Friday so I could have it on Tuesday didn't show up until Thursday so we had to leave with no water pump installed which means no water in the Monaco until we arrive at the next park....I paid EXTRA for this service.......
My sure Flo pump would not shut off. Replaced it with the hydro max pump because of the reviews.The pump has great pressure and is very quiet
Just installed have not really used yet but is supper quiet compared to the factory pump. Has great pressure so far very good!
Pump arrived on day promised, free ship ping.

Our dudes and dudettes are pretty rad! Always happy to dig up info to get you the right part.
I needed to replace the Shurflo fresh water pump in my class C RV. This pump worked like a charm.
The pressure I have expected is not there , I have blew out the supply line coming into the pump, water was coming out from the filler cap without any problems, so no plugged lines, drained the water heater , blown out the system through the low level drain valve water came out from the water heater no problems there either , I started out with the manufacturing setting on the adjustment screws, the pump does not perform like the video that E-tailer posted where the shower water hit the shower celling , if someone can email me what to try to do, that would be apricated.

Thank you for providing the troubleshooting you've done Jens. Since you've already verified that the supply line, water heater, and plumbing system are flowing properly, I would recommend checking the inlet filter at the pump to make sure it is clean and free of debris. Also verify that the pump is receiving a full 12 volt power supply, low voltage can reduce pump performance. The HydroMax P25201 is factory set to approximately 55 PSI and the manufacturer recommends leaving the adjustment screws at their factory settings. Increasing the pressure adjustment typically does not provide a significant increase in flow and can affect pump operation. If the pressure still seems lower than expected after checking the filter and voltage, please let us know and we can continue troubleshooting.
