CH flow pipework still hot even with CH turned off

[fixitflav]

Hi all, update on my original problem, rather than remove the 3 port valve to see if it was repairable I spent £20 on a new one, fitted it today & it is all working as it should now, no hot flow pipes when CH is off!!!
So a big thanks to all who offered help & advice, very much appreciated & hope it helps someone else in the future if they get this problem.

Great, good to hear it's fixed. If you're that way inclined, why not take it apart and see if you can see what was wrong with it.

Not a wiring fault with your new salus then?

I am that way inclined! So will be having a look & see if I can make a good spare of it

Ok, so finally got to strip down the valve & found the face that seals the CH side of it had a build up of hard dirt on it, very small but enough to allow water to pass by. The stem & seals are all in good order so I’ve cleaned it all up, reassembled it & will keep it as a spare.
Just for info though, if anyone has the same problem, stripping the valve is very simple, so don’t be afraid to give it a go (hindsight is a wonderful thing!)
