water hammer

[John Attew]

We too are having trouble with water hammer. Have recently had fitted mono bloc taps...do they turn off too quickly? Also had a new shower head fitted. Could there be air in the system? Cannot detect where the noise comes from...could be in the roof. Anybody got any ideas. (husband was a plumber but now very retired)

Well John im surprised your husband couldnt help you. lol.

Dependant on how old the property/plumbing is there could be a possibility that the ball valve in the cold water tank is bouncing while filling the cylinder when the hot water is drawn off. This can be remedied by fitting a new part 2 valve or arresting the ball cock. This is assuming your on a gravity system.

Could be that the old taps were fitted with copper and as such held the pipework firmer, the new monobloc may be connected with flexis which now allows the pipework to wobble about and cause hammer.
