I have a Glow-Worm 30cxi?

the system pressure drops but the internal valve to re-pressurize doesn't seem to work, presumably a new valve?
Colin Smith, February 2008
really dodgy design of the fill valve( typical gloworm)
you need a replacement fill valve as you will find it has sheared off internally also a handfull of o rings because if you change a component on this boiler it will leak from another!
