How to install a 12 volt water pump.

[Woodman]

Hi all, new to the caravan world, just bought a 2009 OB 16.49.1.

We have used it once and love it so far, how ever it does not have a 12 volt pump for the sink, only a hand pump and mixer for mains pressure.

Has anyone installed one or know how to install one a 12 volt pump, using the current mixer.

If you have any images of installed pumps either factory fitted or otherwise that would be great, to give me some ideas on where to install and pipe layout.

Happy caravaning, Cheers the Woodman's.

Welcome to the forum woodman.
Do a search on the forum for pump and have a look through the threads for some of the pics. You should be able to get some ideas from those hopefully.

Hi Woodmans
I'll have a crawl under mine on the weekend and see if I can maybe do some kind of drawing for you

I put an extra pump in to a filtered tap on the sink as we have one tank for drinking only and two for showering and washing, pictures below.

Cheers Guys, thinking and looking at your pics Stomper, I should be able to tee into mains line, and run pump from tank to mixer, was also going to plum in a non return into the main line to stop water being pumped down main line when only on tank water. hopefully the 12 volt pump has a non return built in. And also have a tee piece for the hand pump when battery dies.

Holding thumbs all works out.

Hi woodman
If you don't have hot water in your van you can use the hot water side of your mixer tap for the pump driven water. That's the way i did it in ours and it works really well. Turn the tap to cold for mains water turn to hot for tank water and you still have the hand pump if needed.

Our pump has a one way valve and I think they all do so you should be fine
