Can't repressurise Baxi Combi 80e

[diy_darren]

Maybe I'm stating the obvious, but have you opened the bleed valve on the new radiator so the air can escape and the water get in? You have the valves either side of the radiator open?

I just did the same thing on exactly the same boiler. Opened the new draincock for 30s to flush out any crud, then the bleed valve to let the radiator fill. Followed by bleeding the rest of the radiators in the house and checking the boiler pressure was ok.

Ten quid later (plumber) turns out that there should be three black taps. One on each of the bits where the boiler meets the wall and one where the flexible pipe starts. Where there should have been a third one on the flexible pipe there just a screw. Turns out it had been removed for some reason. All sorted out now and only ten quid so am happy! Thankyou for all your help and suggestions
