How do i re pressure a valliant boiler?
I bled a radiator and lost all pressure in the boiler? How do i refill it?

a small screw driver will be needed and a small black handle will need to be turned underneath boiler ensuring its turned off after filling

find filling loop to fill ch with cold water,make sure its turned off when you get to 1-1.5 bar,if pressure keeps rising when heating is on your expansion vessel needs recharging,corgi reg installer neededfor this job

cant see a key, where can i get one?

`iv only ever filled one of these boilers but from memory there should be a plastic key supplied with the boiler,maybe stored in the drop down flap , at the bottom of the boiler there should be a space for the key and a simpler quater turn will start to fill the boiler, make sure u have any other valves open or it wont fill . good luck.
