Hello everyone,
Just a quick query regarding expansion vessels as used in a pressurised CH system with combi boiler, in this case, an Ideal Classic Combi FF280.
The 8L vessel should have an initial charge pressure of 0.75 bar.
The system design pressure is 1 bar.
I suspect the expansion vessel may have lost some of its charge, though the diaphragm is definitely not perforated (no water coming out of valve).
Is there any way I can check that the expansion vessel is correctly pressurised without draining down the system? If so, what kind of pressure should I expect if I connect a presure gauge to the "dry" side of the expansion vessel if the "wet" side is at 1 bar or so?
Many thanks.
