Hello,
I think I need to repressurise my Combi 77F boiler. I recently bled some of the radiators and the pressure gauge is now at pretty much zero (assuming I'm to read the black needle and not the red one). The heating still kinda works but some radiators are hotter than others and some are still cooler at the top.
I understand the theory behind topping up the system but I just want to make sure I'm doing the right thing.
Below is a picture of all the piping and that. I think I need to connect the red and white circled areas with a hose that I'm going to have to buy because I can't spot one anywhere else. If I turn the red circled valve water comes out so I'm pretty sure that's the right one but the white circled one has no valve; just a cap which I'll need a tool to remove. Any advice would be appreciated.
