Inspection & Testing

Although the use of continuous runs of copper tube minimizes the possibility of leaks, systems should be tested according to the code of the authority having jurisdiction. This usually includes pressure testing with air or an inert gas (carbon dioxide or nitrogen) at the pressures and for the durations required.

After all appliances are connected and the gas is turned on, a meter dial test should be conducted for the time period required, and every connection, joint and valve should be checked with an approved leak detector solution.

At this time, the installer should also inspect the system to ensure that striker plates are installed where required and the tube has not been physically damaged or kinked. Damaged or kinked tube should be repaired or replaced in accordance with the requirements of the authority having jurisdiction.

The system is now complete, and a final inspection by the authority having jurisdiction (AHJ) is required during the test period. If the system passes inspection, an approval tag will be issued stating the system is in compliance.
