How Do You Bleed A Radiator???

[LJ4174]

Hey Folks...

My house was built in 1942 and I have radiator heat. It's just about time to turn the heat back on, but I think I need to bleed the radiators or something. What must I do? No, I haven't lived here since 1942 I've only lived here for a year a half, that's why I'm asking : ) I didn't do anyting to my radiators last year...

I noticed there are 2 valves by my boiler. 1 for a water supply line and another one coming out of the pressure tank(?)

How much water do I let in? Do I need to let water in? Do I just turn the valve on and then go to each radiator and open the valve on the radiator up until water comes out? I don't want to put to much water in, I'm afraid that may damage something.

I have a cape cod home and I noticed last year that the radiator upstairs, the only one, in my bedroom was cold. I'm thinking it's because there was insufficient water.

Any advise on this would be great...

Thanks...

Jesse

P.S. The valve by the pressure tank appears to be stuck open. It's a copper valve and I see corrosion around it. How do I open that if I need to? Just force it or get some sort of spray? Thanks again...

Hey Jesse, your USA systems are sufficiently different than ours that we aren't likely to be able to be too much help. I thing you need a more local guy. Good luck!
