It occurs when you abruptly start or stop the flow of water in a pipe. It's caused by the pipe's movement, and its cure is to add a pipe support at a location that will oppose the direction of motion. First check for a support that may have loosened or developed a gap between the support and the pipe. If it's behind a wall it's obviously more difficult to fix. First try clamping the pipe where it penetrates the wall. Just a wooden wedge between the pipe and wall opening might be enough. Not to worry though, it's noisey but only in severe cases is it a threat of damageing the pipes and leaking. |
Pipe by sink has no brackets on it so i found out when sink came away from wall.it feeds bathroom sink then out to kitchen sink and washing machine (down stairs bathroom) and the bloke that owned our house before us was a bodger so we found out when we started to decorate.
