What is the standard pressure for residential gas line installations?

In residential gas line installations, the standard pressure is typically set at 2 psi. This pressure level is appropriate for natural gas systems that supply homes, as it is sufficient to deliver the necessary volume of gas for appliances such as furnaces, water heaters, and stoves without posing a safety risk or requiring overly complex equipment. Maintaining this pressure ensures that appliances can operate efficiently while minimizing the risk of leaks or malfunctions.

The other pressure levels mentioned, such as 1.5 psi, 5 psi, and 10 psi, may pertain to specific industrial applications or high-pressure systems. However, they are not standard for residential settings, as greater pressures can increase the risk of issues, including potential damage to appliances or increased chance of gas leaks. Thus, 2 psi is the widely recognized and safest standard for residential installations, ensuring both performance and safety for home gas systems.
