Hi - last night I had to drain 1 radiator to change the valve (?) on it as it was leaking. Did this succesfully - but because I had drained it pressure had dropped right down. I raised pressure by using filling loop - then tried to re-start the system. Pilot light is OK and Pump seems to get going (but now much v.loud?) - but main flames (?) don't seem to start - ie - no hot water and no heating. Please help - it's *&^ing freezing!.
It's a Vailant combi boiler.
Cheers guys,
