Normal
The NG here is pushed through large main lines beneath the street with a 3/8" line going to each house. At the house, it's expanded and regulated, to a 1" pipe, and then broken down to 1/2" or 3/4" black pipe that runs through the house. Newer houses use corrugated yellow pipe, which I'm not fond of because it is easily damaged.Anyway, we once clipped the underground feed to a house with a backhoe, and that thing whistled! We crimped it off and called the gas company. At first, they were annoyed that we tried to stop the flow, then they were glad because they would have had to evacuate the neighborhood if we hadn't.I don't know the psi of the gas coming from the street, but it was pretty high. Hard to imagine that would be reduced much in the cold, especially since it's 6' underground, where the temps are stable, around 50 degrees. I DO know that sometimes a meter will go bad. But different areas probably use different systems, as you said.
