Here's the issue. Whenever my cold tap is turned off quickly, the pipes in the house vibrate wildly. It a loud, dull noise. Build up pressure I assume. It happens in every room but only the cold tap, not the hot. If it were just that, I could live with it - I'd just turn the tap off slowly, bit it also does it when the washing machine fills up. When it's finished filling up and the water intake switches off, the god awful noise starts. The only way to fix it is to turn the cold tap on full blast and then turn it off slowly. Any plumbers on here that can assist?
