Hi, I've not had much dealing with bleeding radiators before, so I’m sorry if this is a bit of a silly question :dunno:
I have lived in a new build house for about a year and half now, i decided today i would give the radiators and the heated towel rails.
The 2 radiators furthest away from the boiler let a good bit of air out before water come out and the rest didn't seem to have air in, the issue I’m confused about though is out of the other radiators that didn't have air in, all apart from 3 let clear water out, the 3 that didn't let clear water out let what appeared to be black water out, the strange thing is, the 3 that let black water wouldn't come from the nozzle that the air / liquid is supposed to come out of, it all seemed to spurt from what seems like a little behind the nut that you loosen, I’m not sure if this black water is a little too thick and that’s why it can't get through to the normal nozzle?
All the radiators that bled with clear water all come through the outlet nozzle fine.
Because i wasn't too sure what best to do, i just tightened radiators with black water back up as they were spurting everywhere a bit and not just tricking down, should i just have let it carry on coming out but kept an old towel around it to soak it up and eventually it would turn clear and start coming out of the outlet nozzle?
Also, if i did just need to let the black water to run until it was clear, what if that made a lot of water come out, does the boiler just replace this lost water the next time it is run?
The boiler i have is a Potterton Promax Ultra 40 Combi.
Thank you
James
