hello, can anyone help me with the vailant 828 please?
my pressure has gradually dropped to below 1 and i would like to top it up as i had absolutely no water at all this morning (it has returned now without much pressure)
i have struggled with the 2 black levers underneath, and i think opened them totally, although they were very difficult to move, but the pressure gauge remains about the same.
i remember my builder attempting this a few months ago, and it took at least 15 mins to raise the pressure, saying it was the slowest increase he had ever seen.
Am i doing something wrong? the black lever towards the front/middle of the boiler is facing away from me, and the one on the right hand side facing towards me when they are in the open position.
please help, i am clueless!
thank you.
