Hi to you all
My Nan has a potterton combi 80 boiler,that has been playing up recently.
The problem a few weeks ago was that one minute the pressure was reading 1 bar,and about ten minutes after the boiler was on,it was reading 3 bar.
I checked the exp. vessel ,and there was no water coming out of the schraeder valve,although the vessell was only about 0.5bar,so i re-pressurised it to 1 bar.Also the prv was letting by when the pressure was about 1.5 bar.So i changed the prv and everything seemed to be ok for a week or so.
I went round this morning,checked prv-all ok.
Checked vessell,no water coming out of the valve but it still has this problem of pressure rising from 1 bar to 3 bar in about ten minutes.
Does this mean that the exp. vessell could be shot or could it be something else?
Any help and advice greatly received.
