How do I increase the pressure in my Worcester Bosch combi boiler?
I bled the radiators in my house because they weren't getting very warm, but I think I over did it because now my pressure gauge is reading 0!!
How do I top it back up? And do I need to top it up to 1? The gauge goes from 0 to 4.
I have a whitish grey key which i stick in a hole but then i'm not quite sure what to do. Any plumbers out there that can help?
The key fits into a hole in the charging link, the hole is nexty to a little grey k nob, put the key in and turn to the left as you face it, then turn the little k nob, again to the left and you should here water go into the system, when pressure is 1.5 turn the little k nob off again (not tight, they break) and remove the key by turning to the right and pulling down, there will be a splash of water but nothing to worry about, go easy on this because it is plastic and easily broken. Thanks Glen, prob got thumbs down off some ar*e who gave a wrong answer and i gave them thumbs down.
