I was trying to replumb some part of the hot water pipe leading to the
washing machine. I tried to shut off the hot water by closing the valve
on the cold water feed to the hot water tank. It is stuck solid. It has
a red round disc like thing on it which is very difficult to reach into
the airing cupboard and turn.
I am afraid that too much force will damage the compression fittings. Is
there any way to loosen it? Does this mean it needs replacing?
Any ideas . . . please?
Thanks in advance.
