I went to change the refill valve /arm in the cistern, about the limit of my diy skills. So underneath the cistern we have a flexi hose with an isolating valve attached. I turned the screw head in this a quarter turn to shut off the water in preparation for removing the arm inside, then I noticed the valve was dripping a bit, seemingly from where I had just turned the screw. I immediately turned it back a quarter turn to where it was, but it's still dripping, quite fast, has filled a cup in just under an hour. Tried turning the screw slightly one way and another in case it needs to be exactly in a certain position, but no good. I've just had another look and discovered it appears to be dripping from the exact opposite side to where the screw head is - if I feel this side with my fingers there appears to be a circular type piece that rotates as you turn the screw. It's this where is leaking from. Any ideas how /if this can be stopped, or do I need a new valve? The whole toilet system has only been in for about 5 years. Have I possibly dislodged or disturbed the fitting somehow by turning the screw? (I thought this was going to be the easy part!)
Thanks in advance for any advice.
