When I flush the toilet in the bathroom, run the tap or have a shower, when I turn the water off, I'm getting a really loud banging noise (loud enough to set the dog off thinking we're being robbed lol). Normally, you'd hear the cistern filling up after you've flushed, but I'm really not hearing any obvious noise of it filling up though it does eventually.
It's not been happening for long. Any ideas what it could be?
