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?
 
Charge the system up. Isolate the flow and return valves. If it drops upon opening them some hours later then it is a leak somewhere other than the usual boiler prv issues
