Moving a rad in a flat, all on one level. Running of a condensing boiler. Rad to be moved has the drain off. Straight forward rework of the flow and returns but:
Do I drain the whole system even tho the main f and r pipework is all below the drain off so wont empty.
Or shut off all lock sheild and trvs on the other rads on just drain off from the valve to drop the pressure
Either way surely when I split the sub floor pipework theyll still be holding a lot of water at atmospheric pressure. Tips?
