I have a one-pipe cast iron radiator that leaks at the joint where the steam enters the radiator(not at the shutoff valve or the steam regulator). I have tightened the nut, but it still leaks.
Floor damage indicates that this is an ongoing problem in the house, which I recently purchased.
Is there something (teflon tape, etc.) that will help stop the leak? I intend to pull it apart and drain it out, but wanted to know if there's a recommended material to stop the leak.
I also have a similar small leak in the basement at one of the joints. I think the heat guy said to seal it off with silicone caulk. Is that recommended?
