2 pipe steam Radiator not heating / Traps / System Replace ?
Tx for the reply.
The traps at the end of the radiators are Hoffman Specialty 17c.
At the end of main steam in the basement, on each side of the run, are Hoffman No. 75 Main Vent Air Valves one rated 15 lbs max, the other 10 lbs.
The 10 lb is obvioslsy older. It leaked at one point about a month ago. Father took off nipple and poked around top. No longer leaks water but now constantlt spews steam. (other one hisses air at begining and stops which I assume is its function) I'm assuming the old one needs to be replaced ??
There is also a 10 lb valve on one side of the return pipe near the boiler but I'm not sure what does is for.
