leak from overflow pipe

almeria1

Noticed dripping from overflow pipe today and on checking in loft found water level
in expansion tank just up to pipe. I thinking of getting up there tomorrow and trying to bend the float arm down a bit however if I am not successful I'll buy another float etc. On looking at B & Q I see they advertise both low and high pressure float arms . I do not know which type I require. I live in the Berkshire area if that makes any difference to things.

High Pressure most likey unless your in a high rise block and you will need to change the whole ballvalve not just the float, unless its just the float has split, but even then its possible with the wear from trickling water the valve seat may be knacked, so play safe for what it will cost;)

Dont forget to turn the mains water OFF while you do it:)
