What it means
Residential gas lines may be black iron, corrugated stainless, or copper where code allows. Joints are threaded or mechanically coupled and must be pressure tested after any modification.
The distinct odor of mercaptan signals a leak. Do not operate switches or flames if you smell gas; evacuate and call for repair from a licensed plumber or utility qualified contractor.
Why it matters in Santa Cruz County
Santa Cruz County homes mix older iron gas lines in crawl spaces with newer CSST in remodels across the mountains and beach flats. Earth movement on hillside lots in the Santa Cruz Mountains can stress exposed fittings after storms.
