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.

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

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.......

Easy to install,perfect replacement for my 1999 Shurflo 2088-404-144.Much quieter, too.Thank you for your help in making this purchase.
by:
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.

Followed directions, installed, immediately the pump worked and provided more water flow than the original pump that I replaced. Thanks.

bought as a spare on hand prior to travel.

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.

Still works great after a year of hard use. No leaks or loss of pressure!

by:
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.
by:
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,

by:
Worked great for 11 months, used in RV for kitchen sink and low-flow shower. Actually used only 3 of those months. Stopped dead one day while in use. Glad etrailer can manage the return because Valterra was not very responsive. Since I am currently needing the pump (RV on rural property while building a house)I had to buy another pump, then will get a credit when I return the defective one so I have to go without for a week until it is delivered. If I didn't need it, I could have returned defective and gotten replacement without the charge, other than shipping. I would reconsider buying Valterra if I had it to do over. A 2 year warranty is good, but replacing a water pump is not fun.
by:
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

by:
Great little pump, it's well built and worth the money. I've had other, but this is top notch. I like the fact it comes with the straight bar fittings and the filter with it, meaning you don't have to order them separate. So, far it works like a dream.

    I looked up your Shurflo 200-210-39 and based on it's specs the HydroMax RV Fresh Water Pump # P25201 would work great as a replacement. It's similar in flow and PSI as well.

  • Replacement Water Pump for Shurflo 2088-403-144
    The HydroMax RV Fresh Water Pump # P25201 referenced in your question works as a direct replacement for a 3-gallon-per-minute (GPM), 12V pump. Based on my research, it looks like your existing Shurflo 2088-403-144 pump features these same specs so it should work great as a replacement. I do recommend verifying the specs on your particular model though as it looks like there may have been a couple different versions of this Shurflo pump.

    Hello Rebecca, Thanks for writing in! I’m sorry to hear your pump gave out on your trip, I hope you were still able to enjoy your time. I don’t have a database that shows exactly what components are installed on each specific trailer, but based on my research, your unit should have a 3.0 GPM (gallons per minute) / 55 PSI pump. You can confirm this by checking the label on your current pump. Replacing it with the correct unit will restore reliable water flow for boondocking and help prevent...

  • Adjusting Pressure on HydroMax Water Pump
    While the HydroMax RV Fresh Water Pump, # P25201 can be adjusted, the Tech Rep at Valterra recommends against doing so stating that the units are set at the factory for best results. You will want to adjust the By-Pass spring by turning the screw. Screwing the by-pass screw in will raise the pressure and unscrewing the by-pass screw counterclockwise will lower the pressure.
