When preparing to conduct a leak check, what is a must for new gas piping systems?

Conducting a leak check on new gas piping systems requires a full inspection for any open fittings or ends. This step is critical because open fittings or ends can allow gas to escape, creating a potential safety hazard. Inspecting for these vulnerabilities ensures that the system is sealed properly before being put into operation.

Addressing open fittings minimizes the risk of gas leaks, which is essential for maintaining safety standards and preventing hazardous situations. A thorough inspection at this stage helps to confirm that all connections have been made securely and that there are no areas where gas could escape. This preventive measure is vital in ensuring a safe and reliable gas system.

The necessity of thoroughly examining the system for open fittings does not involve simply replacing fittings, closing valves, or calibrating gauges, which are important but not foundational steps in ensuring that the piping is leak-proof upon initial setup.
