What happens if appliances in the piping system are found to be leaking during a test?

When appliances in the piping system are found to be leaking during a test, it indicates that there is a compromise in the integrity of the system. This situation is critical because leaks can lead to safety hazards, including the risk of fire or explosion due to the flammability of gas. Identifying a leak during testing means that there is a failure in the containment of the gas, which requires immediate attention.

Recognizing a leak signifies a need for further inspections to determine the extent of the issue and determine whether repairs or replacements are necessary. However, the presence of a leak does not imply that appliances can continue functioning or that the entire system needs replacement without first assessing the specific locations and severity of the leaks. Immediate repair of the leaking components is essential to ensure gas safety and compliance with applicable regulations.
