Help!!
Problem with 2 year old combi. Pressure rising from .75 bar cold to 3.25 bar hot. Dropping pressure through pressure release valve. Called it Corgi man, he changed the PRV but said that to repressurise the expansion vessel the boiler has to come off the wall!
Ravenheat say it does not
I need to know where the re pressurising valve is so I can argue with one of them
