Hi
My boiler is losing water pressure, have to recharge every couple of days.
Today I let out the system water pressure until it read zero on the gauge.
Tested the expansion vessel and almost nothing in it.
Recharged with pump to 1 bar and noticed the boiler water pressure gauge had risen to 1 bar also.
Does this indicate a faulty pressure vessel membrane allowing the air pressure into the water side?
Thanks
