just gone out to the van to disconnect the hoses for the morning and there is water sprayed everywhere in the back, there is a leak where the pipe goes into the shut off valve, had a fiddle and now the solenoid has stopped working, all the wires are in tack and the fuse is ok, but how can i bypass it so that i can fill my tank with out removing it? its between the 2 pre-filters, can you disengage them?
