Gas Line Replacement in Charlotte, NC: Buried Lines and 811
Gas line replacement in Charlotte, NC
Replace a gas line when the pipe itself is the problem: corroded along its length, too small for the appliances on it, or in the wrong place. A single loose fitting or a worn appliance connector is a gas line repair.
A new appliance that never had gas is gas line installation.
If you smell gas, stop reading. Leave the area right away. Call Piedmont Natural Gas at 800.752.7504, or 911, from a neighbor's house or somewhere away from the smell. Do not go back until Piedmont or emergency responders say it is safe.
When the line is safe, tell us which appliances it feeds and whether the run is buried. We check whether a local plumber can take the job.
Buried lines: 811 will not find yours
Many replacements involve a line buried in the yard, for example to a detached garage, a pool heater or an outdoor kitchen. Primary utility lines are marked through 811, but private lines on private property are not, so the plumber has to trace your own line. The crew should still contact 811 three working days before digging so the public lines around it are marked.
Gas piping is permitted and inspected by Mecklenburg County Code Enforcement. North Carolina requires a permit for the installation, extension, alteration, or general repair of any heating or cooling equipment system.
| Path | When it applies | What drives effort |
|---|---|---|
| Repair | One fitting or appliance connector | Shut-off access, permit |
| Section replacement | Corroded span with sound ends | Length, burial, permit |
| Full replacement | Undersized or worn-out whole run | Length, routing, permit |
Adding a big appliance, such as a tankless water heater, can make an existing line too small. Rinnai says its tankless heaters run on a 3/4" or 1/2" gas line as long as enough gas flows. An undersized line can stress the unit.
Do I need gas line replacement or a repair?
Only when the pipe is corroded along the run, undersized, or failing at several joints. A single connector or fitting is a repair.
When is a corroded line a full replacement?
When a plumber who has seen the pipe finds corrosion along the run rather than at one spot. Describe what you noticed and where.
Next step
If you smell gas, leave first and call from outside. Otherwise say which appliances the line feeds and whether it runs underground.
