• close the gas cock

• read the lockup pressure

• document lockup results

Any regulator pressure over _____ inches WC will require the regulator to be replaced.

• 14

• 15

• 16

• 17

During a timed pressure drop test, no pressure drop should be detected. If there is a pressure increase due to thermal expansion _____, and if there is a pressure drop _____.

• locate and repair leak…and retest…repeat the test

• locate and repair leak and repeat test…locate and repair leak

• locate and repair leak…locate and repair leak

What should be documented for a timed pressure drop test with a test apparatus?
