Hi.
I'm having problems with finding the reason for that pressure to keep falling to 0. The customer rang me saying it took 4 hours for it to drop but I'd image he had it on all that time. When I went out I checked the pressure relief valve, drained the boiler and recharged the expansion vessel to 1 bar which I charged to 1 bar (might be slightly too high), couldn't find anything leaks. I forgot to check if the pipe to the expansion vessel is blocked but could there be anything else at fault?
