I have a leak on my toilet and was wondering how to go about fixing it. It is on the cold supply pipe that goes up vertically into the base of the cistern to fill it. - forgive me for not knowing the technical names!
Along this pipe there is a kind of inline valve - it has a screw which can be turned 90 degrees to turn the supply on and off. his valve leaks unless it is turned off. The water seems to be seeping from the "edge" of the valve.
What is the recommended way of foxing this? Does the valve need replacing usually?
