At what inlet pressure is the gas supply considered less than safe for residential use?

In residential gas supply systems, the inlet pressure at which gas is supplied is crucial for safety and proper operation of appliances. An inlet pressure of 2 psi is generally recognized as the maximum allowable pressure for most residential applications. Pressures above this threshold can pose safety risks, such as increased stress on regulators and appliances, potential leaks, and improper combustion.

At pressures exceeding this amount, the risk of hazardous conditions increases, as residential systems are designed to safely handle lower pressures. Therefore, when an inlet pressure is above 2 psi, it is not considered safe for residential use. This delineation is important because proper functioning of appliances relies on maintaining specific pressure ranges, ensuring efficiency and safety for residents.

In contrast, pressures below 2 psi, such as 1 psi and 1.5 psi, are within safe operating limits for residential systems, providing adequate fuel supply without introducing excessive risks.
