Thanks for the reply. It has microswitches on the taps, first thing I did was try the other taps but it made no difference unfortunately. I do have a multi meter with me, I used it to check the connections on the back of the water inlet housing. Only 1.5 volts going to pump. Could just be a bad connection somewhere but I've no idea where the wiring goes or how to access it.

I've emailed a local mobile caravan mechanic to see what his hourly rate is. I'm hoping it might just be a case of running some new wires through to get us back in business.
