Thanks, couldn't see for looking and it was obscured by condensate drain hose. (Thats my excuse anyway).
Going to try and pressurize tomorrow.
Thanks again
Can anybody tell me how to repressurize the expansion tank on a CSI85?
I have been led to believe by Ravenheat that there is a bike type valve on the tank.
Ravenheat will not give me any further advice as I am not Corgi registered. I could understand if they refused to tell me...
