Residential Steam System - No Traps?
I'm just a homeowner... so bear with me...
I have two pipe steam system, 100 yr old house in NE, new furnance, new main piping, new main and radiator vents. System gets good'n hot (too hot on 2nd floor) and bangs like crazy (did this before the new furnace).
Question - each radiator has two valves (supply and return) - both are full open. From what I can tell, none of them have traps on the return. Its been like this since I moved here ~20 years ago.
Could it be there are no traps, and could this be my problem? Any ways to check?
Thanks for listening, and sorry if this is contractor only forum.
