air vent removal

jan_3

I have just read the book "we got steam" and I ready to tackle removing the radiator air vents to check them (some radiators aren't heating up). I have heard that the vent can break off leaving the threads inside. Should I spray something on the threads prior to trying to loosen them? What do I do if the valve breaks off? Are there other things I need to be aware of? I assume I can't turn the heat back on until the valve is replaced. This is an old system so I doubt the shut off to the individual radiator will work. Maybe I should begin this process from that point, make sure the shut off works before removing the air vent. What has been your experience. Thanks Jan

removing air vents

You should have no problems if you go slow. USe a pair of channel locks if you have to to remove the vents, just go slow and easy with steady pressure. IF the vent breaks off, there is usually enough of a stub to use a small pipe wrench or locking pliers. Don't worry if the valve works. With steam all you have to do is shut off the boiler for a while. Turn it back on after the vents are changed. If one does break off, an easy out and a 1/8" NPT pipe tap will be needed. Easy job if you are mechanically inclined. If not call in a pro if the vent won't budge.
