    Hi there,
    For a few years I've had a water hammer in a three storey victorian warehouse conversion. My solution so far was to turn down the water pressure, which works for the annoying sound but my water pressure is not satisfactory.
    Recently I've decided to try and tackle the problem, and after reading online I've tried a solution suggested in a few websites (turning the water supply off - turning all taps on from top to bottom - turning the water supply on - then turning all taps off from top to bottom).
    Problem solved! no water hammer while the pressure was at max. However, after about an hour and some weird sound from the pipes while a tap in the top floor was on, the problem is back.
    Does this mean air is entering the system somehow? if so where should i look for the air leak? and solution ideas?
    Many thanks,
    Tal

    You need an engineer to look at the system.

    Turning your stoptap down does not reduce the pressure , it reduces the flow.

    what exactly is happening to cause this water hammer, 9 times out of 10 its usually caused by a plumber who doesnt know what pipe clips are.
    I.E badly clipped pipes
