Marietta's gas picture
Marietta Power & Water supplies electricity and water, but not natural gas. Residents are pointed to certificated gas marketers such as Gas South, Georgia Natural Gas and SCANA, which is how the Atlanta Gas Light system works. No city gas system turned up, so AGL is treated as the pipe utility; if your bill names a different company, follow that instead. Leaks go to the pipe owner, never the marketer.
The Cobb County seat has a wide range of housing. Census survey data put the median build year at 1987, with about a third of homes from before 1980. Older houses around Marietta Square and along the historic streets are the most likely to have black iron pipe extended many times, while subdivisions from the 1990s on often use corrugated stainless tubing.
City of Marietta Building Inspections issues permits for changes to existing buildings, with plumbing and heating among the most requested. Addresses with a Marietta mailing address outside city limits fall under Cobb County.
Black iron or flexible tubing?
| Black iron pipe | Corrugated stainless tubing (CSST) | |
|---|---|---|
| Typical in | Older Marietta houses | 1990s and newer homes |
| Install | Cut and threaded, more fittings | Long flexible runs, fewer joints |
| Common issue | Corroded joints, leaking unions | Missing or poor bonding |
| Extra requirement | Proper support and drip legs | Bonding to the electrical grounding system |
What to watch for
- A sulfur odor. Get outside, then call.
- A hiss near the water heater or furnace connection
- Yellow, lazy flames on a range or gas logs
- Soot on vent pipes
- A pilot that won't stay lit
- A gas bill that rises without explanation
When to schedule
Gas work tends to pile up in the first cold snap of the year, when furnaces and fireplaces start running. Getting old connectors replaced or a new branch run in late summer avoids waiting during the busy season. Spring is a good time to add a line for an outdoor grill or patio heater before you need it. If you are swapping a water heater or range, have the plumber check the connector and shutoff at the same time rather than reusing old parts.
