    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!)
