Hello all, I am no plumber but have always managed to at least top up the pressure on every boiler I have owned. Just moved into a new place and there is a British Gas Branded Worcester-Bosch CDi Combi. The pressure has dropped right down which tells me I need to top up the system. But all I have is a plastic key and a plastic black hole to put it in.. Can someone explain in a step by step guide what I am supposed to do? There's no instruction manual left here so I stuck.. I could have taken a chance and turned something but didn't want to play around in case I break something! Help appreciated, cheers. R.

Would be worth getting manual from W's site, but
Shove key in hole, up as far as it goes. If you turn it 90 it should lock, in a vague sort of way.
Then turn the grey(?) knob to the right of it, anticlockwise, several turns, until you hear the familiar gushing noise. Let if fill SLOWLY. If your feet are getting wet you're doing it wrong.
Screw knob shut at about 1 bar - careful they can shoot over.
Remove the key - which will dribble a little water.
