I am desperate for help – after 4 visits from plumbers and still no solution to my problem.
I live in a block of apartments and for the past couple of month have been subjected to a rattling noise in the pipes – mostly at around midnight and 4-5am, sometimes at around 6.30pm and then all weekend.
The plumber who has been to visit my apartment and others in the block seems to think it is water hammer but has been unable to find the offending tap.
The noise is loudest in the upstairs bedroom (which is also the top of the block) and there is a hot water system in the wall. When the pipes are making noise you can feel the vibration in the cold water pipe that connects to the hot water system and it stops whenever you run the cold water tap or flush the toilet in the upstairs bathroom.
Is this water hammer? We thought it may have been the hot water system but several plumbers have said this is unlikely.
What can we do to minimise or eliminate the noise?? I have had to deal with the body corporate for so long that it now seems necessary to take matters into my own hands – too many sleepless nights!
Would it help to install a water hammer arrester somewhere in the apartment??
Sounds like there is a stool that is not shutting all the way off.Probably got a bad ballcock.Check the stools .Ihave run across this problem quite a few times in the 35 years that I have been plumbing.
