So almost all the steam traps. There’s like 4 left in the house. Those radiators heat but not super hot. Is it possible those traps leak and that’s why I am not seeing any pressure build up? I don’t hear much water hammer if any though??
Hello Jamie! Thanks for all your help. Update, I have replaced almost all of the packless radiator valves and steam traps. Most of the radiators are now very hot and it doesn’t take long! I have 2 Gorton #2’s installed for the main vents. I removed the F&T guts and a check valve that was installed on the wet feet urn probably back in the 50’s. I skimmed the boiler last night as well. All I have left is to insulate the main boiler piping. I have a question. On my pressuretrol I can’t tell if I really have the cut in Set? Even with that new 3 lb guage it never builds any noticeable pressure. The boiler just shuts off when the thermostat is satisfied. So I taped off the main vents and the cut out worked at around .75lbs but the cut in not sure?? When the boiler kicks on the burners immediately start boiling? Any thoughts? Am I just venting that good!
