Customers find the water pump to be well-made and easy to install, delivering strong flow and reliable pressure for showers. However, the reliability and durability receive mixed feedback - while some report it works well, others mention it stopped working after a week or broke within months.

    Embarking on RV adventures is now a breeze thanks to the incredible WASSERMANN RV Water Pump. With its powerful 12V DC motor, this pump ensures a robust water flow at 3.0 GPM and 55 PSI, catering perfectly to all camping water needs. What sets it apart is the whisper-quiet operation, a true delight. Installation is a walk in the park. Having used it extensively, I can vouch for its consistent performance, delivering reliable water pressure for showers, sinks, and outdoor activities. For a durable and efficient RV water pump, look no further. Highly recommended for a worry-free camping experience!

    Im a RV Technician and I use this pump for water testing, fresh system flush, winterizations, works great have it running off a Milwaukee 12v battery with one of them adapters. This thing works great with water, antifreeze, this pump puts out plenty of flow and awesome pressure, shuts off when pressure is built, comes with a bunch of fittings and the strainer, can't beat the price and how much of a workhorse it is! Highly recommend for rvs and other uses such as off grid, or for liquid transfer.

    Great fresh water wash down pump for boat with low amperage pull

    Full content visible, double tap to read brief content.

    I installed this on my boat for my fresh water pump replacement. Pressure is perfect for washdown. I chose this pump because of the amperage.. I think it's less than 5 amp pull where the other ones are sometimes 17 amps or more and that's too much for the way my original pump was wired so check that before you buy a pump so you don't pop fuses. This installed perfectly and the mesh screen filter is quality. The water flow is sufficient for washing down the boat deck after catching fish. Quality item and comes with plenty of fittings. This pump was the closest to the OEM one that came on my boat and with the same amount of flow and amperage so overall Happy so far. I wonder how long it will last but since it's freshwater hopefully many years.

    The pump is as advertised and has worked with no problems. Installation is a breeze. Water flow is adequate, not extraordinary. Probably right there at 4.0 gpm/45 psi, like the manual says. The plastic 3/4" to tapered fitting adapters are cheap-looking and I did not end up using them, but they probably would have worked fine with no leaks. Power consumption is phenomenal. I can go boondocking 2 weeks with this and only use 0.8-1 kw hours! It is, though, bordering on the loud side. There's no using the pump in our RV without everyone knowing about it. Maybe consider some noise dampening accessories, if you're looking into buying this one.

    We ordered this pump to replace our water pump in our RV that we live in full time. Shortly after it arrived and had it hooked up The pump stopped working. I contacted customer service and they sent me out a new pump. That pump also had the exact same problem because it was the same pump. So I contacted customer service again and let them know that we are having the same issue. I was assured that they were sending me a new pump and a new part just in case because they realized that the issue was in a wiring harness that apparently he started melting and was faulty. I never received the part to fix the pump and I never received the new pump after the second one died. My emails went unanswered for 2 months. So I went back to my sureflow because I know that one works properly.
