1. Boiler external piping must be hydrostatic tested in accordance with PG-99 of ASME Code Section I. 2. ASME B31.3 hydrostatic pressure must be raised above 1.5 times design pressure in proportion to yield strength at test temperature divided by strength at design temperature but not to exceed yield strength at test temperature.

What is the safe pressure for a hot-water-heating system?

Jan 19 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve.
