Richardson Steam System 2 pipe with ell traps

What is the recommended operating pressure? I have those special TRAP Ells on each Radiator. What is the replacement for these traps?

I having problems with water from the only vent on system? Have dry 2 returns?

    At what pressure are you operating the system at now?

    Crank it down

    this system was designed to run at less than a pound. I'd replace the Pressuretrol with a Vaporstat that maxes out at 16 ounces.

    The Richardson ells have no moving parts. There should not be any need to replace them. But if the air holes are clogged, the radiators won't heat. You can clean them- see chapter 15 of Lost Art for details.
