You got a semi-blocked mains water supply mate. The pressure can still build up, but the flow is limited. Make sure all valves/stopcocks are turned on & check the dynamic pressure at a tap on an ajoining property.
Happy New Year to you also eh, Happy??!!
I hope you & your family had a great Christmas?
Think about it chaps, he's running out of water!!! Something is blocked.
Maximum duration of the membrane is assured as
the membrane itself cannot bend or rub against the
plate, as fixed above to the connection and below to
the flange.
My theory is that once the membrane is empty, the air pressure prevents the water from travelling from bottom to top unless the water pressure is greater than the air pressure.
