What is the minimum working pressure for residential natural gas systems in Alabama?

The minimum working pressure for residential natural gas systems in Alabama is established at 0.25 psi. This pressure is sufficient to ensure that gas can be transported effectively through residential piping systems and delivered to appliances while maintaining safety and efficiency.

In residential applications, gas appliances are designed to operate optimally at this pressure, which ensures that they receive the right amount of gas for combustion. Operating at a pressure lower than 0.25 psi could lead to inefficiencies, incomplete combustion, or difficulty in operating gas appliances, whereas higher pressures may necessitate additional safety measures and equipment not typically required for residential applications.

This standard is consistent with industry practices, thus helping to ensure safety and efficacy in the installation and operation of gas systems within homes.
