My problem is this. We've recently had a plumber fit a new bath and sink. He used most of the old pipework but had to replace some with new. What's happening now is that after the central heating has been on or after running the hot water for a while (eg. running a bath), when I come to turn the sink tap on I get a large hammering noise from somewhere. This only occurs when the flow rate is lower and it disappears when the tap is turned on fully. The noise is like a pipe banging on the floor boards combined with a large vibration. Any ideas? Do you need more info from me?
