Hi All,
I want to replace a lock shield valve in my central heating system. It’s a combo boiler system. If possible, I’d like to do it without draining the whole system.
Is there a way to just drop the pressure so I can whip the old valve off and replace it without letting too much water out of the system?
Cheers.
