Welcome! Here are the website rules, as well as some tips for using this forum.
I have a small room at the back of the house, not much bigger than 8 x12 feet. It's an old porch, converted into a sunroom years before I came along, and I'd like to add an entryway door to convert it into a mudroom/entryway. Problem is, there are two radiators there now (one pipe steam). When the boiler is on, it's really hot. But since there is no insulation to be found, it's cold the rest of the time.
My plan is to unscrew the pipe from the main and use a plug to cap the old T fitting. A little pipe dope on the threads and a pipe wrench and voila? Can it be that simple? I really don't think two radiators in that space have ever made any sense, it should be plenty warm (once we insulate) with just the one (these aren't small radiators, either, the same size as what's in every other room in the house.
I've also read online differing opinions on the use of teflon tape. My general sense is it shouldn't be necessary if the threads are in good shape. Is it ever a good idea?
Thanks for your help!
