Thanks for the info. The ex vessel is holding pressure so I switched on the CH. True to form after 25 mins the pressure gauge was showing 2.5 bar ( all rads hot) whereas the pilot went out. It seems worse now because after 15 mins with the pressure gauge now showing 1 bar I cannot get the...

So how do you read the pressure of the expansion vessel? What gauge do you use? The gauge was attached to a footpump Thanks

As far as the expansion vessel is concerned, I have pushed in the valve and no water could be seen. I have de-pressurised the system and attached, with difficulty a pump and pressurised to 1 bar, is this enough?. Then refilled system to 0.7 bar and tried. The gauge still went to 2.5 bar in 25...

aav was replaced and all rads bled by plumber. After that he sort of gave up, suggested that I replace the pressure relief valve (leaking) and the boiler overheat, (both done) then replace boiler and left. As the boiler is approx 10 years old then if replacement is the only option then so be...

Thanks. All the rads are hot and the pump changes note if turning the speed down, so I would assume to be working. I have noticed however that if a hot tap or the shower has been running then when switching it off, a sound like rushing water can be heard through the downstairs rads (CH off)...

Boiler : Glowworm Swiftflow 75 combi. Problem : With central heating swiched off the boiler works fine and DHW on demand. With central heating switched on pressure rises from 0.7 bar min to 2.5 bar over a period of 25 mins. At this point the pilot light goes out and will not stay lit...

I have now had the over heat switch checked. Athough it appeared ok it was changed. The thermocouple was checked as per the instructions and found ok. The heating was switched on, all the rads warmed and the gauge pressure gradually rose to approx 2.5 bar. Just after this the pilot light...

I have checked the expansion vessel, no water so I pumped in some air and refilled the boiler. Started central heating, rads all warm, ran the shower for a time and switched off. Pilot light remained lit, after 5 mins it was still lit. It is fixed me thinks. Checked it after 1 hour and still...

Boiler- Glowworm swift flow 75/80. Problem appears to have started after removing radiators from wall to decorate. With central heating turned off boiler appears to operate normal ie pilot light remains lit at all times and increases in size when turning on hot water at the taps...
