What is the maximum allowable pressure for residential propane systems?

The maximum allowable pressure for residential propane systems is generally set to 10 inches water column (wc) or 0.4 psi. This standard is in place to ensure the safe and efficient operation of appliances that use propane in residential settings. Having a maximum pressure limit helps prevent risks associated with overpressure, such as leaks or equipment damage, which could lead to hazardous situations.

When working with propane systems, it's crucial to maintain precise pressure levels because appliances are designed to operate within specific pressure ranges. Exceeding this pressure can lead to improper functioning or potential safety hazards.

The selected answer reflects established safety standards and practices in the industry for residential propane use, showing an understanding of how pressure regulations are applied to safeguard both equipment and residents.
