Strange knocking noise
Posted: May 4th, 2021, 1:49 pm
Hi Guys, this is a weird one.
Occasionally when hot water is drawn in the bathroom, a loud knocking noise is heard in the pipework.
It will only stop if the cold tap in the kitchen is turned on for a few seconds.
The noise never occurs if cold water is drawn in the bathroom.
It does appear that it will only happen if the cylinder has hot water.
Any ideas where I should look
thanks
