What is a critical step when working with gas piping in residential homes?

Both inspecting for physical damage and testing for pressure are essential steps when working with gas piping in residential homes.

Inspecting for physical damage is crucial because any damage—such as dents, corrosion, or leaks—can pose significant safety hazards, including the risk of gas leaks or explosions. Proper inspection ensures that the gas piping system is secure and safe for use.

Testing for pressure is equally important as it verifies that the gas piping system can contain gas without any leaks. This pressure test ensures that the system will operate safely under normal conditions. It is a standard practice to conduct pressure testing after installation or repair to confirm the integrity of the piping.

Together, these steps form a comprehensive approach to ensuring the safety and functionality of gas piping in residential settings, making the option that includes both steps the best choice. Installing new piping alone does not address the necessary safety checks that must occur to protect the home and its occupants.
