help! Lost Pressure!

DARYALS

OK, the pressure is still at 2-3 bar so I think the boiler is somehow not getting rid of the excess pressure, it seems to build up three bars and stay there. I have closed the valve and the pressure is still at 3. I'm now sitting with no water on and the pressure level measuring 2. Well I suppose I have got the pressure up? Any other ideas??

Its building up because instead of being closed off at the valve the mains pressure is going straight thru and into the boiler... so you turn the mains stopcock on and the pressure rises straight away... indicating the valve is in the open position, to close it put the blue part back on and turn either clockwise or anticlockwise to close/open... once in the opposite position that it is now you can turn the main stopcock on and the pressure on the boiler will not rise... like how it was to start with... then you can control the amount of pressure yu but in by the blue control tap by as i mentioned tunring it clockwise or anticlockwise...

it needs to be put in the closed position like it was at the start, the put your water back on again... and now you can start to check the radiators for air using the bleed key... this will remove the air and thus lower the pressure on the boiler gauge

This indicates the water flow

Mains stopcock>>>>>>>>>>>blue valve open>>>>>>>>>>>boiler

Mains stopcock>>>>>>>>>>>blue valve closed<

if the blue valve is closed you can turn the stopcock on without worry and the pressure on the boiler will not rise at all...

ok thats great! I now fully understand how this bloody boiler works! One small problem, the blue key has now SNAPPED (AAAAAAAARRRRRRRRrrGGGGGGGGGHHH!!!!). Is it possible to control this valve with a small pair of mole grips?

the_dead_parrot

lol one thing after another... dont worry they are cheap and alwasy snap on me... yes the blue part should have pushed onto a little rectange shape... a pair of adjustable grips, a correct size spanner or mole grips should be fine... dont be to brutal wth it tho it should move fairly easily...

by the sounds of it youve got to grips with the situation now... as said once the air is out and the boiler is running the pressure should sit around 1-1.5 after the heating has been on a little while it may rise to 2 or just above... which is all good... anymore problems just give me a shout

Tell you what, gents, I've been following that with bated breath! Certainly better than watching TV, as the snow / hail falls outside.

If you've heard a little voice saying ' give him your telephone number' - it was me! Excellent result. Plumbing by Email - even my wife glanced over my shoulder and was impressed.

the_dead_parrot

lol wel usually the main cost assosiated with plumbers or other engineers is the extortionate call out charges... this cuts that right out, I didnt even have to move

reverie

Gosh, I agree with Mike. It was so exciting! Well done to the Parrot! Are you secretly a superhero?
