FAQ

Leak tests are legally required any time there is an interruption of service, meaning the flow of gas was stopped for any reason. It’s simply testing the integrity of the system's plumbing joints following an interruption of service or out-of-gas situation. National Fire Protection Association guidelines (NFPA 54 2006, 8.2.3) state that “Immediately after the gas is turned on into a new system or into a system that has been initially restored after an interruption of service, the piping system shall be tested for leakage. If leakage is indicated, the gas supply shall be shut off until the necessary repairs have been made.”
