What is the required gas pressure test for piping 200 feet or less?

• A. 50 psi 60 mins
• B. 15 psi 15 mins
• C. 5 psi 10 mins
• D. 25 psi 30 mins

Answer: (B)

Gas piping pressure testing checks for leaks by raising the installed piping to a specified test pressure for a set time. For piping 200 feet or less, the standard requirement is to pressurize to 15 psi and hold for 15 minutes. This level is high enough to reveal leaks in typical small-diameter gas piping without risking damage to fittings or components, and the duration is long enough to show whether the system holds pressure reliably. Larger or longer runs would require higher pressures or longer test times, but short runs use this 15 psi for 15 minutes as the baseline.
