Hi, I wonder if anyone can help? I have an Abbey Iona caravan that I have been living in for 3 months. Last month the water pump failed so I bought a new one, a Whale 12V High Flow Rate Submersible pump. It worked fine except it didn't stop pumping unless
I switched it off manually - this I fixed eventually by locating the pressure regulator and turning it anti-clockwise until it was set correctly. However the next day it stopped working at all when I turned the tap on, even when I turned the pressure regulator
clockwise as far as it would go. The only tap which causes the pump to start is the shower cold tap! When that's on, I can get water through the other two taps, kitchen and basin. Turn the shower off, the pump stops
