Hi, I'm new to this forum and have a problem with a banging / knocking whenever the cold water supply is turned on or off. This has been noticeable for a few weeks but seems to have got worse recently.
Having read up a bit online I guess that this is "water hammer" but it is not just on one tap - it happens with all taps, toilets, washer etc. I understand that this is a pressure problem and have turned the stopcock in the house down to try to get rid but to no avail. The water company have checked the supply and have said pressures are normal.
Any ideas what could be the cause of this and how do I resolve it? I'm thinking maybe the stopcock is faulty, although it does shut off the supply as normal.
Any advice would be appreciated.
Thanks
Martin
