harrycatcat1 Posted November 17, 2020 Report Share Posted November 17, 2020 I need to replace this valve as its dripping from the other side of where the screwdriver turn off is. It seems longer than the usual smaller isolating valves so I need to get a replacement size. Any help appreciated π Just now, harrycatcat1 said: I need to replace this valve as its dripping from the other side of where the screwdriver turn off is.

TIGHTCHOKE Posted November 18, 2020 Report Share Posted November 18, 2020 Looking at your enlarged image there appears to be an attempted fix with PTFE tap on the thread of the upper compression fitting. Might be worth trying a new olive and the existing parts. Quote Link to comment Share on other sites More sharing options...

The old one is 4" long and all the ones in the usual places are 3" and I didn't want to have to be cutting and shifting pipes so it might have to be getting a plumber in.
