if it is a whale type fitting look behind the pump inlet on the inside of the caravan,there should be a screw surrounded by a nut.undo the nut and turn screw in and out to adjust. see how too........

Are you sure it has pressure switch. The last Challenger i had was a 2001 and that had Micro-switches on each tap.
good point,check to see if there are wires going to the taps.if so you have a micro switch system. tiny switches inside each tap that are operated when you lift the lever.

------------- the only silly question is the one you do not ask.
Thanks again to all who made helpful suggestions it turned out to be a pressure switch. The problem we had was that we heard the whale pump work when no taps were on! At the time the 240 mains link was disconnected and I now believe it was that the battery was too low as now on mains link up problem appears solved. Does this make sense.
