My friend is trying to change his ball valve in the loft cistern.
But he says his stopcock will not shut off. He says he has turned it by hand clockwise and anticlockwise but no joy water is still running. why is this - could it be seized up after years of non operating?
I advised him to turn the external stopcock off - he says his is in his driveway. But he will need a special external stopcock key from a merchant. Would he be right to turn it off this way, then cut the old stopcock off (after draining the water in pipe) - and fit a new one (compression type). I said if he cuts a bit too much pipe off, he can add the new stopcock and then a bit more pipe and a straigh coupler up to the original rising main.
Any more help on this subjext/advice I can give him? ...
