Gas service and homes in Lewisville
Lewisville is a town of about 13,000 in western Forsyth County, and the 2014 state Utilities Commission report includes all of Forsyth in Piedmont Natural Gas's service area. Whether there's a main on a given road is a separate question, especially in the town's rural-zoned areas, so ask Piedmont about your address.
Most Lewisville homes date from the 1970s to the 1990s. Census survey figures put the median year built at 1987, with about 35% from before 1980. That puts many houses near the line between rigid black iron gas pipe and the flexible CSST that became common later. You may find both in one house, especially if a newer appliance or an addition was tied into an older system.
Gas piping permits in Lewisville go through the joint Winston-Salem/Forsyth County Inspections Division, which serves the town. That's the same office that handles Winston-Salem itself, so the process will feel familiar to anyone who has pulled a permit in the city. Outdoor projects, such as a built-in grill or a fire table on a new deck, are a typical reason to extend a line, and they get permitted the same way.
Black iron or CSST for a new line
| Black iron pipe | CSST (flexible tubing) | |
|---|---|---|
| Typical in | Older Lewisville homes | Homes built or updated more recently |
| Installation | Cut and threaded on site, more fittings | Long runs with fewer joints, easier to route |
| Best for | Exposed runs, short branches, durability against damage | Routing through finished walls and attics |
| Special requirement | Support and proper sealing at joints | Bonding to the electrical system |
| Mixing the two | Possible with the right transition fittings, sized for the total load | |
Signs to look for
- Rotten-egg odor. Evacuate first, then call.
- A hissing noise near piping, a valve or an appliance
- Flames that are yellow or uneven instead of blue
- Soot on vents or around the water heater
- Yellow tubing with no bonding clamp near the meter or panel
Seasonal notes
Spring is a good time to add outdoor gas lines for grills, fire pits or patio heaters, when the ground is workable and before summer use. Fall is better for checking furnace and water heater lines before heating season. Planned work that needs a permit and inspection takes longer, so start early if you have a deadline. If you're replacing a gas water heater or furnace anyway, that's the easiest time to fix an undersized line or swap a worn connector, since the appliance is already disconnected.
