Hi there my apartment is all hooked up to the pump, the dishwasher, taps, showers-everything!! My pump is activating all the time but I can't turn it off because obviously when I'm asleep I have the dishwasher on etc and also a plumber came last week and turned it off and it never came back on!!! no water and expensive to get a different plumber out to fix it. I had a problem with a dripping shower which I thought was why the pump was going all the time. The plumber came to fix it though and now the shower is no longer dripping but the pump is still going all the time!!!! I have noticed there is constantly a trickling noise in the boiler also...Im terrified the pump is going to ware itself out and I hear they are expensive to replace, anyone know what could be wrong?
