My boiler is losing pressure every day, main combi boiler, no noticeable leaks, I’ve topped up expansion vessel, but when on its up to 3 bar and dripping like mad outside, do you think it’s a prv issue or expansion vessel fault? The error says to top up and check auto air vent.

Getting new boiler in couple of months and I’ve read as a temporary fix I could maybe drain a radiator to put air in it and get pressure that way?

Cheers

Paul
