What is the typical safe working pressure for residential gas lines?

In residential applications, the typical safe working pressure for gas lines is around 0.5 psi. This low pressure ensures that gas can be delivered safely to appliances while minimizing the risk of leaks or accidents. A pressure of 0.5 psi is sufficient for the efficient functioning of household gas appliances, such as heaters, stoves, and dryers, and it conforms with safety standards.

While options like 5 psi, 10 psi, and 2 psi might be seen in different contexts or industrial applications, they exceed the standard operating pressure for residential gas systems, which could introduce safety hazards. Higher pressures are generally used in specific industrial or commercial scenarios, but for residential installations, maintaining a pressure at or below 0.5 psi is critical for safety and compliance with regulations. This standard helps to ensure the integrity of the gas delivery system and prevents potential accidents associated with higher pressures.
