This motorized, self-priming pump creates smooth, consistent flow in your RV's fresh water system. Works as a direct replacement for a 3-gallon-per-minute, 12-volt pump.


The replacement water pump in our rv came with needed parts and took minutes to install. After a year of use including winterization with rv antifreeze the pump is still going strong. I have made several purchases from etrailer and believe in their business model. Thanks again!


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


Great replacement for our old WP. Easy to install and works better than the old one.


Replaced the non working pump in my 2006 Roadtrek with this guy. I’ve been living in my RV for 5 months now and the pump hasn’t missed a beat.



I’ve been living in my Roadtrek full time this last year and this pump is still going strong.


This was a great purchase. I’m very happy with this new pump. Installation was super quick and easy.


I am an "old" customer. And as usual their service and product was just super. Been dealing with T-Trailer for many years. Always friendly, and professional service --- And great products.


Good quality and perfect fit replacemen t!



Pump is still working perfectly and is way better quality than the one that came on my camper. Highly recommended!

@Corey We're glad the pump is working well for you!


I have bought several items from etrailer and every product is as advertized. Perfect fit every time. Prompt delivery. Some of these items were not easy to find but you have come through each time.


Great pump! A tad noisy but works really well in my 2014 23ss Roo.



Installed this water pump a year ago. Works likes a charm.bplenty of power to move water thru out camper no problem. Made it thru a tough cold colorado winter and started back up with zero issues. Def will buy again if it ever goes out. Happy camping!!!


Replaced my original Shurflo pump fromy 2009 Fourwinds Windsport with this new HYDROMAX.
PEEFECT FIT! 30 MINUTES TO INSTALL. E-TRAILERS TRACKING OF MY purchase is the best I've ever used. On time delivery and was able to follow it every day.
Great price for me pump! Works excellent and much quieter than my old Shurflo. I ALWAYS JAVE A GREAT PURCHASE EXPERIENCE FROM BEGINNING TO END WITH E+Trailer



Just as strong and quiet as day one. Excellent product!


I’ve taken my trailer out 3 times since installing the new water pump. So far so good! Thanks,!


Ordered for 2009 Jayco 256RKS. Exact replacement. I'm happy!


Got here quickly . Great customer servi ce


The pump is slightly larger than the original and has a bypass valve. The installation was easy and operates much quieter than original we won't know how it performs till spring time when we get back to camping

Started using the new pump in May of 22 worked very well all summer on last tripend of septpump had a very small leak under the regulator I removed 2 screws holding regulator there was a small plastic bump from manufacturing that wasnt removed during assembly I cut it off and reassembled so far no leaks


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.



Pump works just fine. No problems, no leaks, still fairly quiet,


Works as designed, No issues after the one year of service!


Perfectly happy with my pump, availability, price and ease of finding one.


So happy with this pump!
Very easy
to install and so quiet.
I now have equal pressure throughout the rv!
Thank you, again !


I rigged up this pump to my city water connection on my 37 foot 5th wheel trailer. By doing this I bypassed having to constantly fill my water tank. This pump actually improved the water pressure that we get in most RV parks on a city connection!


Shipping was very fast. We have used Shurflo pumps in our last two 5th wheels. I have replaced 3 pumps in 7 years. I carry a new pump as a spare. I am very disappointed in the last 3 Shurflo pumps. I am carrying this HydroMax pump as my new pump to install when the time presents itself to replace the Shurflo Pump that was installed on 7/2021. I am hoping for a better experience with the HydoMax pump than Shurflo.


This just what I needed and works just fine. Thanks


Excellent Pump, Excellent Customer Service at Etrailer also!


Very Quiet


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.


Works perfectly! Thank you guys for all of your help!
