: My basic question is 4.5 psi too high if so what is the normal PSI for steam home system?
Residential one-pipe steam systems were designed to operate around a 1 psig pressure.
One pound of pressure will drive steam up hot pipes 2/3 of a mile. So the rule-of-thumb for those who like such short-cuts is:
"For every half-mile that your top-most one-pipe steam radiator is above the boiler, increase the boiler pressure 1 psig."
