Advice needed water system not working

does the water pump come on when you open the tap?

does the water pump run all the time or even not at all?

does the water coming out of the van underneath, only do so when the tap is opened?

whereabouts under the van is the water coming from, is it overflowing from the fresh tank (unlikely) or have you got a disconnected tap hose that is spewing out water when you open a tap?

Sounds like the Frost Protection valve is open or one of the drain taps. Sometimes happens when things move or fingers touch things.

Hi i have a small problem,  

Write your comments here...I would see the doctor if I were you .

Have yo checked the pipe is not split or joint come apart, is there a built in overflow or something.  Does the pump work when teh tap is lifted and go off when its shut?

Have a look under the sink! Lift the wooden panel and you should see the cold and hot water drain taps. On our hymer (2002) the cold water is a lever-operated valve ie up for open and flat for closed. The hot water drain is a screw-down nylon valve. Make sure the latter is screwed down tightly, and the former is in the horizontal position.

we have had exactly your problem when the hot water tap wasn't screwed down fully. Driible of  water from the taps and loo flush, but water flowing out of the external drain point.

Come on Eddie, tell us if you've fixed the problem!
