I have a combi boiler that is letting by on the filling loop. Can stop it and is relatively gradual ( 1 bar to 3 bar in 4 hours).No easy way to isolate mains as stop cock isnt working properly. Also needs full drain down as filling loop has been put straight into flow pipework so no easy fix for tonight. My question is when the pressure exceeds a certain bar count will it automatically go through the boiler overflow pipe. Also will it do this if i keep the boiler switched off?

Should escape through pressure relief valve. To get you through the night and for peace of mind, any chance you opening drain off valve to let pressure release and leave open til you can get to fix filling loop? Will give the system a pleasant flush anyway!
Would have to be one and isnt! Do you have to be corgi to work on filling loops (i.e can i get a normal plumber in) or is this included only within Corgi reg work?

Provided it's not integral part of boiler then any plumber can do it.
