New Home, steam bubbling from valve stem?
I've been reading through lots of posts and have ordered "We Have Steam Heat" and am looking forward to reading it when it arrives. Until that happens, I have one issue I would like to see if I can fix a) quickly and b) myself:
The house we bought two months ago, built in 1947, has one-pipe steam heating system. There was a sunroom addition put on some years ago, and a radiator was (poorly) piped to heat it. The previous owner stated that she would just "shut off the room during the winter". Well, we intend to use this room year-round. The problem is the radiator.
The radiator in this room barely/rarely works. Right after we moved in the air vent on the end broke (my kids had never seen radiators before), so I replaced it with one I bought at HomeDepot. The radiator now seems to heat up SOMETIMES, and never all the way across. On top of that, the valve handle is missing and we just noticed that there is steam escaping/water bubbling up from the valve stem. (Pictures below). For right now, until the book comes, I'm really just interested in making the steam stop, so as to make sure none of my little noisemakers gets hurt. Can I do this myself?
Thanks in advance. Go easy on me - I have very little idea what I'm doing....yet!
