Service Line & Meter Set
The small pipe from the gas main to a building, ending at the riser, service valve, service regulator and meter on the wall.
What it does
The service regulator, installed and maintained by the gas utility, drops distribution pressure to what the building is allowed to use, and the meter measures it. In Canada a single family home gets at most 14 kPa (2 psig); commercial and industrial sites 35 to 140 kPa (5 to 20 psig). Piping after the meter follows the B149.1 code.

| Commercial, industrial | 35 to 140 kPa (5 to 20 psig) |
