Ok I know the Glow worm 30cxi is an issue itself but she has held up pretty well until now (6 years old). However she's started leaking water from the bottom quite substantially filled up about 6/7 buckets 3 gallon buckets already. Strange thing is hot water and heating working fine, water pressure has only dropped by 0.3 from 1 bar 0.7. Had a plumber pop over he reckons hydro block minimum £250 bummer of job apparently, but spoke to another plumber in pub last night and he said pressure should have dropped if hydro block !!! Anyone got any ideas ? I've had a quick look at manual but ain't got clue and so much water leaking seems to be coming from all over and spraying too !!! Phoned Glowworm they not having it out of warranty !!! Shall I take the hit and get a new one ?
