hi the water pump on our caravan keeps running wont turn off we have looked inside van and found just inside 2 wires a whit and yellow one looks like its not right in could this be the problem we dont want to make it worse can you help !!!!!!!!!!!!
If you haven't already cured it have a look at the inlet pipe for a balance pressure valve turn the top knob clockwise to close it turn a tap on about halfway turn the knob anti clockwise and the pump will come on and when the valve starts to click stop turning the knob and turn the tap off the pump will run on then stop. If you haven't got a pressure valve then I can't say what it is.
