Hi I wondered if some one can give me some advise please. My overflow pipe out the side of the house was leaking a lot of water. It turned out to be the hot water tank. The diaphragm valve had perished in the ballcock system. I changed the ballcock system and it seemed to work fine. It stopped when it should have and the water level did not reach the over flow. Now, however, there is little to no water coming from the hot taps upstairs. The cold works fine. A bit dribbles out the hot bath tap and nothing comes out the hot sink tap (both mixer taps) yet downstairs the hot kitchen tap works fine. Any advise?
