Thanks a lot! I've filled it up to 0.5 bar and it went up to 0.65 when I turned it on again.
So far working ok, and have contacted the landlady to have the boiler serviced.
The pressure has been below zero on the scale for as long as i can remember. Is it possible that it's been running...
Hi, I've got a Valiant Combi boiler and the pressure meter on the front has dropped to zero.
How do I go about repressurising? I haven't got a manual or any experience, but if you give me some directions I might be able to sort it out!
On the sticker on the inside of the door of the boiler...
