Water Hammer

[leebmillar]

I replaced 2 sets of basin taps and the only problems is that the upstairs bathroom cold tap makes a loud banging noise and pipe work vibrates, the only way to resolve the problem is to turn the mains water pressure down and it seems to be fine but the customer now complains that the pressure for her bath is not strong enough ?? Please could you advise ?

Thanks

try clipping the pipework

The pipe work is clipped above ground but unable to check under the floor as this is tiled.

You have probably fitted disc taps,they cut the water off quicker and no rubber cushion,you have not turned pressure down by closing main stopcock,you have reduced flow rate,quite different,if works however,fit isolation valves to tap,they should have been fitted anyway and close these down slightly to offending tap

imho

Sometimes the washer on the stopcock gets loose and starts to vibrate with water passing over it check the washer and replace if necessary.
