we have a half flow of hot water in the kitchen, (which I believe is because of gravity) but no hot water upstairs in the bathroom. We have recently refurbished the bathroom and the plumber mentioned the diaphragm on the boiler for the water seems to have stopped working? Would this be the likely problem we have?
