This brand is fitted to all Winnebagos and really is an excellent product. It lets you have a pressurised system - like the mains in your house. Now it isn't perfect as you will get fluctuations but it comes on as soon as you turn on a tap and you can easily get it to just "dribble" for teeth cleaning whilst saving water. We like the rubber mounts supplied as they reduce noise no end. In practice it is not a good move to have a totally silent pump as if you leave the mains on and you run out of water the pump will run continuously.

Manufacturers blurb:- This 12 volt, 2.8 gpm multi fixture demand water pump features a patented pump head that is actually three independent pumping chambers, giving you three way dependability.
