WASSERMANN RV Pump, 12V Self-priming RV Water Pressure Pump 4.0GPM 45PSI with Pressure Switch, for RV Marine Camping Yacht Garden, 12Volt DC Fresh Water Pumps RV Water Pump 2088-554-144 Replacement

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.

I created a transfer pump to run off 12 volt to move water into my RV from a storage tank. This pump moved plenty of water and has yet to cause any issues. It has multiple times transferred 100 gallons of water in one sitting without issue. So far I have been impressed with the quality. I'm building my next transfer box for a buddy and I will be making some changes. I will not be changing this pump though, it's been a rock star.

Excellent pump! Installed it in my RV and it works flawlessly—steady water pressure at 45 PSI with no pulsing or noise issues. Self-priming feature makes setup simple, and it handles sinks, shower, and even outdoor use with ease. Solid build quality and very reliable. Great for RVs, boats, or camping setups—highly recommend!

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.

Purchased 2 of these and work very well . I live in my camper a few months out of the year and have not had a problem with these. They give you an assortment of fittings , tape and clamps . Worth the money

Used for main water on our sailboat. Works great.

Wow. What a well made pump and extremely easy to install. Two wires and two hoses and it’s done. It came with everything I needed, including some pretty darn handy clamps.

Worked perfectly good value for the money.
