    Re: Pressure testing residential gas systems

    I usually test mine at 12 psi, then the inspector can kick it down a couple pounds if he wishes.

    the code requires (upc) 319.0 10 psi test or less should be performed with guages of 1 / 10 pound incrementation or less.

    of course med and high pressure tests have different guages, this is just for low pressure, 1/2 lb test.

      20# for 24 hours on a 30# gauge . That what Baltimore county wants and every county is different.
