Question: 1 / 455

A propane service regulator would normally deliver pressure at?

Pound to 11 in. w.c.

A propane service regulator typically delivers pressure in the range of 5 to 11 inches of water column (in. w.c.). This pressure range is appropriate for residential propane appliances, ensuring they operate efficiently and safely.

When using propane, it’s critical to maintain the proper operating pressure to avoid issues with combustion and performance of the appliances connected to the gas supply. The pressure delivered must be sufficient to meet the requirements of the appliances while staying within safe limits.

The other choices include either lower ranges or inappropriate units for the context of a propane service regulator. Ounces are not a typical measurement for gas pressures in this application, and the upper limits indicated in those options do not align with standard operating pressures for propane.
