Hello everyone, my Son has an eldrly Barlo Duo Combi Boiler which is running just fine, however the presure drops away and I want to check the Air pressure in the Expansion Vessel, the problem is that I cannot see (or feel) any Valve, the boiler has been fitted tight into an alcove and whilst its probably possible to wiggle the Side Panels out I doubt I could get to a valve buried down there, I have the original Installation instructions but strangely they make no mention of checking or pumping up the e/v and in a very nice and detailed exploded diagram you cannot see a valve, does anyone have any ideas where it might be?
Look forward to hearing from you and thanks in advance,
Steve.
