I recently changed hot/cold taps in a downstairs WC.. During this process I drained the hot water tank and turned off the cold mains.... Upoin refilling the immersion and turning the cold back on I discovered that the cold water in the bathroom upstairs was only a dribble!..
what have I done..!.. An airlock maybe, but not sure how this would have happened?..
