  • Steam Boiler - Pressure Cutout switch - Handyman WIRE

    Dec 20, 2006 · Residential steam boilers are meant to run at about 1 psig, so the setting should be adjusted down, or you'll have slugs of water banging around in the upper piping eventually. Pressures over 3 psig kill steam vents upstairs by squashing the internals. One pound of pressure will drive steam up hot pipes 2/3 of a mile.Learn More

  • Correct Max pressure for a steam boiler? - DoItYourself

    Nov 21, 2010 · Since residential steam boilers run at such low pressures the safety valve never operates on its own and even hand testing of the safety valve is limited by the fact that a safety valve should not be hand tested with less than 2/3 of its set pressure.Learn More
