Hi
Can anyone help - the pressure on my Vokera Excell 80 SP boiler has been near the bottom of the red gauge for weeks. I think I need to turn one of the taps but am not sure which one and don;t want to do any damage. Is it the black 'adjustable stopcock' underneath on the right? If so, should it be open or closed? Or there is a white 'tap' underneath in the middle, should I move that?
Any advice gratefully recieved!
