When should a gas line be tested for leaks?

A gas line should be tested for leaks after installation or any modifications to ensure the safety and integrity of the gas system. This testing is crucial because any new connections, joints, or changes in the system can potentially introduce leaks. The primary objective is to verify that the gas line is airtight and functioning correctly before it is placed into service or before further work is done that could risk disturbing the line.

While there are other appropriate times to inspect for leaks, such as during annual maintenance or when a gas odor is reported, the critical point is that initial installation and modifications necessitate a leak test to confirm that no unsafe conditions exist. Conducting these tests at the appropriate times not only meets safety regulations but also protects the health of individuals using the gas system and prevents potential hazards associated with gas leaks.
