Morning all.
I believe plumbers when carrying out minor repairs of pipe work running from the water tank in the loft prefer to stop the water supply by blocking the hole within the water tank. This I was told can avoid the problem of an isolator valve not working correctly. What do they use and what is the correct name for it. I'm assuming it is some sort of rubber ball or similar.

Tom
