When installing gas lines, what should always be checked?

When installing gas lines, it is crucial to always check existing building codes. This is because building codes are put in place to ensure safety, compliance, and proper installation practices. They provide guidelines on materials, installation methods, and safety distances to avoid hazards such as gas leaks or explosions. Following these codes ensures that the installation is not only legal but also safe for the occupants and the environment.

In contrast, other factors like the color of the piping, length of the pipe run, and type of fittings used, while important, do not supersede the necessity of adhering to the established building codes. Ensuring compliance with building codes helps to prevent potential legal issues, promotes safety, and is an essential aspect of responsible craftsmanship within the HVACR industry.
