Has anyone got any suggestions please? I am trying to drain down my heating circuit to change a faulty thermostat valve on the ground floor. i am a useful diyer but have a few questions before i start if i may ask?
i have a few drops from the ceiling to may radiators, and i believe these both need to be drained separately to get all of the water out of the system? is this true? how can i be sure that all the water is out before i loosen the nut on the old valve? i don't want to ruin the floors (too much)! and want to be sure all the water has gone before i loosen anything.
i will add more inhibitor on re-fill so want to be sure of completely emptying the system for that reason also.
my last point is this: i only have 1 drain valve in my house and this is near another ground floor radiator. but this is very stiff and will not undo. so what can i do to drain my circuit?! also will i need to more than 1 drain valve really as i have 2 drops!
any advice will be fantastic. thanks for helping if you can
