No chance, closed system - BG dont like sharing their knowledge. They also had a program called Xsol which would walk you through the fault finding of certain boilers (including where to place your Multimeter Probes) and what part and how to change it.

Hi all, i thought it would be a good idea to start a post regarding Common Problems with certain Boilers. We've all been to certain boilers where we know almost immediatley the problem (im thinking isars, Suprimas, Modenas). Having worked for BG their laptops contained common specific faults...

Fair do's.... its definatley weeping at the top of the auto air vent.....so is it a case of draining down and then unscrewing the vent with a pair of grips?....oh yeah i've used the prv in the past to reduce the pressure as her son filled it up to 3bar (dont ask me)..but have i gone and...

full drop....its not the actual screwing in cap...its actually the body of the vent...at the top that seems to be weeping....its not actually my boiler but my aunts...but the pressure drop occurs when the boiler is off...so cant be more than over 8hrs.... can i remove the whole body..the...

got a worcester 240 balanced flue boiler..its old...pressure is droppin overnight...auto air vent appears to be weeping round edges.....could this be the problem....and can it be replaced...thanks
