Hi! If this is not the proper forum for such a queston then I am sorry and I'd like to apologize beforehand and hope you don't get too upset at me and my question can be removed by an administrator, or just ignore me
My question is if you have a steam heat pipe that runs from the basement to a top apt, and lets say you don't need heat in the top apt, but do in all the apts below, can you remove the air valve in the top apt and just plug-up the hole, and make a new hole in the pipe in the apt below and put in an air valve there? Will this still work correctly? I mean if the air valve won't act funny because you still have a section of pipe AFTER it that will just be dead. Imagine that the pipe cannot simply be cut at the bottom apt so that now it ENDS there instead of it still going up to the apt on top.
I hope this makes sense. I had to work extra during the night on an emergency and haven't slept yet please bear with me thanks!
