How to stop my pipes clanging

[mtaylor39]

Hi all

About 18 months ago I had a clanging in my pipes whenever I turned my taps off, and also at random times when not using them. Eventually after much investigation we realised it was because next door had a new washing machine installed and the installers had barely opened their stopcock, and the noise I heard was when they were using their taps / washing machine etc.

After 18 months or so of everything being fine the noise has now returned. I have checked with next door and they haven't done any recent work and their stopcock is fully open. Mine hasn't been touched either, so I'm very confused. Add to that there are some occasions where when I turn my taps off it doesn't make a clanging noise, but more often it does make a noise. I am assuming again that the clanging noise when I'm not using the taps is from my neighbours.

The noise comes from under the skin in the upstairs bathroom.

Additionally (and I'm not sure this is linked), since lockdown I've been working from home. When I first started every time I got up out of my chair there was a similar clanging noise underneath where my desk is, which is the other end of the house to the bathroom sink. That's stopped now. But the noise is similar.

Can anyone help with this problem. It's very annoying when I'm in the house all the time.

P.S. I hope the word clanging accurately describes the noise. It sounds like something hitting the pipe in short, sharp way.

The pipe clang when you get up from your chair will be pipes under the floorboards that are touching (or almost touching) the underside of the boards.
It would be worth lifting boards and securing any pipes that are loose or touching the underside of the boards.
That may sort your random clangs too, if not fit a shock arrestor.

Thanks. Turns out the clanging in the bathroom was the same reason as before. However, this time the house two doors down had a new shower fitted. She turned up the stopcock in her house and it's stopped the clanging.

This will be very annoying if every time someone has work done and the stopcock is turned off and then on again to a lower turn it will affect my water.

Any idea why this is and if there's anything I can do to stop it?
