I have a strange noise somewhere in (I think) my shower pipework.
When I turn the hot tap off abruptly at the wash basin there is a "ker-lunk" from somewhere in the shower pipework (I think).
Can anyone give any thoughts about what I need to look for? For example is it likely to be a pipe loose in its mounting?
The bathroom was completely redone a few years ago.
It sounds like a variety of waterhammer to me, of which I am familiar as pipe vibrations at previous houses.
Thanks
Ferdinand
