Hi all,
I know it is an old topic but I'm struggling a bit. The hot water valve has siezed in the open position, I took the head off and tried to turn the the gate but only succeeded in shearing the top off the valve.
I've bought a dayton replacement valve. All other posts mention draining the central heating system, showing a drain on one of the rads - none of my rads have a drain. There is a gate valve underneath the pump which someone has labelled 'sludge', but I don't know where this pipe goes - it disappears under the hot water cylinder. I live in a ground floor flat.
I've tried turning off the supply and outlet on the header tank and then slackening off the valve I'm trying to change - I got about a bucket of water with no decrease in the pressure before giving up on this.
I think I could freeze one side of the valve, but the other side goes straight to a tee piece, with the CH valve.
Any advice would be much appreciated.
Thanks,
Iain.
