In Lewisville, a sump pump that fails is usually a repair job when the float, switch or check valve is the culprit, and a replacement when the motor itself is worn out. Homes on the town's rural edges may not be on municipal sewer, which affects where the water can go. Call the number on this page to be connected with a local plumber in Lewisville.
Lewisville homes and drainage
Lewisville's housing was mostly built from the 1970s through the 1990s. The median home dates to 1987 and about 35% predate 1980, per Census survey data. Many of those houses sit on crawl spaces, and a pump added to keep one dry has often been running for years without a check. Lots that slope toward the Yadkin River or sit low in a subdivision collect more water than others.
Winston-Salem/Forsyth County Utilities provides water and sewer in town, but Lewisville also has a Rural Overlay and rural-zoned areas where homes are likely not on municipal sewer and use a private onsite wastewater system. Whichever you have, sump water needs its own path to the yard. Sending it into a sewer cleanout adds groundwater to a system built for wastewater, and sending it into an onsite system can flood the drain field.
WSFCU's cross-connection control program makes property owners responsible for installing, testing and maintaining backflow assemblies. That matters if a water-powered backup pump is on your list, since it connects to the drinking water line.
Repair or replace?
| Situation | Usually | Why |
|---|---|---|
| Float stuck or switch failed, pump otherwise healthy | Repair | The switch is a small part and the motor still has life |
| Check valve leaks, water runs back into the pit | Repair | A new valve stops the extra cycling |
| Motor hums, overheats or trips the outlet | Replace | Motor failures rarely justify a repair |
| Pump runs constantly in every storm and can't keep up | Replace or add a second pump | Capacity or pit layout is the issue, not one part |
| Rusted housing, unknown age | Replace | An old unit is close to failing anyway |
Warning signs
- No sound from the pump with water in the pit
- Running without the level dropping
- On, off, on again within a minute
- Gurgling backflow down the discharge pipe at shutoff
- Damp joists, puddles or mildew after rain
When to schedule
The easiest time to fix a weak pump is on a dry week before spring rains or hurricane season, not with water rising. Test it by filling the pit with a bucket every few months. In cold snaps, check that the discharge line drains completely so it can't freeze shut where it exits. Plumbing permits in Lewisville go through the joint Winston-Salem/Forsyth County Inspections Division, so if the job adds wiring or a new pit, ask the plumber whether a permit applies.
