When is it necessary to perform a gas line test?

Performing a gas line test after installation or alteration of gas piping and before service initiation is a critical safety requirement. This procedure ensures that all connections are secure and there are no leaks in the gas delivery system. It verifies the integrity of the piping system since even the smallest leak can pose significant safety hazards, including the risk of fire or explosion.

In this context, completing a gas line test before service initiation assures that the system is functioning as intended and meets regulatory compliance. It is a proactive measure to prevent future issues and ensure the safety of individuals who will be using the gas appliances connected to the system.

While it is indeed important to check for leaks when a gas leak is suspected or during annual maintenance, those instances are reactive rather than a standard procedure following installation or alteration. Testing before any appliance is installed also falls short because the primary focus is on validating the integrity of the entire gas line system, rather than just the points of connection for appliances.
