Hi,
I want to replace a radiator in the bedroom.
I have a gravity based open vented system with a feed and expansion tank in the loft.
How do i drain the system? if i open the drainage valve at the lowest radiator and connect a hose to drain the water outside wont the feed and expansion tank keep flowing water through the system?
Do i just force the ballcock to stay closed by lifting it and securing it to something?
Any guidance would be appreciated!
