Hi - I need to drain my central heating to replace the pump, it’s an open vented system, but as the gate valves are also corroded it’s a full system drain first.
I do not have a drain valve that I can find but I do have a downstairs radiator, by a door, that has this - if I undid this bolt and attached a hose would this suffice to drain down the radiators?
and the reason to drain down is to replace this
Cheers
