Ever since I removed and replaced a radiator (whilst decorating) my combi boiler has been experiencing a complete loss of pressure.
It happens like this: I pressurise the system to 1 bar (as per the manual) and the hot water works fine.
But as soon as I turn on the heating, the pressure (as read on the pressure gauge) goes right up to 3 bars and water starts leaking out of the boiler - presumably via the pressure release value.
When the radiators are switched off and the system allowed to cool down, the pressure drops to 0, and the hot water stops working until I repressurise it again.
Any suggestions? Thanks
