We recently had our house plastered which meant we had to disconnect most of the radiators & take off the walls. We’ve had a terrible water hammer in our hot water bathroom tap since. We drained the water from the top of the house, turned water supply off, emptied taps of water... bled the radiators... Can anyone recommend anything else to try? I’ve just had a baby so I’m reluctant to have anyone in the house to fix it.. HELP!
Turn your main stopcock to off and open it a quarter turn at a time untill you are happy with the amount of water delivered at your cold taps and see if that solves the problem. You may have to accept a lower flow than you want to.
