I had an old red dial type stopcock which didn't appear to be working, ie didn't shut off water and was visibly corroded . I replaced it with a standard stopcock but still the water doesn't turn off. I'm beginning to wonder if it is actually the main stopcock but even if it wasn't then surely it should stop the flow of water at some point. It is not under the sink but there is nothing else that it can be. The reason it is an issue is because I have a water leak of 6l/hour and Anglian water refuse to investigate unless there is a working internal stopcock. There are no damp patches or evidence of internal leaks.Any thoughts please?
