Most Lewisville homes are on Winston-Salem/Forsyth County Utilities water, and a hidden leak usually shows first on the meter or the bill. Homes in the town's rural-zoned edges may have different setups, so a plumber checks how your water arrives before testing. Call the number on this page to be connected with a local plumber in Lewisville.

What's typical in Lewisville
Lewisville incorporated in 1991, but a lot of its housing is older than the town itself. The median build year is 1987, and about 35% of homes were built before 1980, much of it from the 1970s through the 1990s. Homes from that era commonly have copper or early plastic supply pipe, along with water heaters and shutoff valves that may be on their second or third decade.
Water and sewer come through the town's agreement with the City-County Utilities Commission, the body behind Winston-Salem/Forsyth County Utilities. The town also has a Rural Overlay, so not every area is served the same way. Some outlying homes may still have their own wells, though no source counts them. WSFC's service line inventory covers lines from the water main to each home, but the utility hasn't published exactly where its responsibility stops.
Common leak types compared
| Type | What you notice | Usual fix |
|---|---|---|
| Running toilet | Tank refills on its own | New flapper or fill valve |
| Supply line in a wall | Stain, swelling or a damp smell | Open a small section and replace pipe |
| Buried service line | Meter moves, soft yard | Spot repair or a new line |
| Well system leak | Pump cycles with no demand | Repair line or tank fitting |
| Irrigation leak | Wet zone, bill spike in summer | Fix the zone valve or head |
Signs to look for
- A meter that keeps turning with the house shut down
- Higher usage on the WSFC bill without an obvious reason
- Water spots under a sink cabinet or around the water heater
- Low pressure that came on gradually
- Puddles or soggy ground along the path of the service line
- A hissing sound in a wall or under the floor when the house is quiet
Timing
A sharp freeze is when weak pipe tends to give, often in an exterior wall or crawl space, so check around the house after one. In summer, irrigation is the usual cause of a bill spike, and if your system has a backflow assembly, WSFC's cross-connection program sets its testing schedule. On a home with a well, keep an ear on how often the pump runs through the season. Permits for Lewisville plumbing work go through the joint Winston-Salem/Forsyth County Inspections Division.
