What is the minimum amount of time required to perform a pressure test on a gas line in a single-family home?

The minimum amount of time required to perform a pressure test on a gas line in a single-family home is set at ten minutes. This duration allows for a thorough examination of the system's integrity under pressure, ensuring that any potential leaks can be detected. A ten-minute test provides a sufficient window to monitor any pressure changes that may indicate a failure in the components of the gas system.

This standard is typically upheld to ensure safety and compliance with plumbing and gas codes, which dictate testing procedures for gas lines. Other options fall short of this requirement, as shorter durations might not adequately reflect the necessary testing time that guarantees both the performance of the system and the safety of the occupants. In practice, conducting the test for at least ten minutes gives technicians a dependable measure of the system's stability before proceeding with use.
