Lewisville's housing runs largely from the 1970s through the 1990s, so many showers here have first- or second-generation single-handle valves whose cartridges and seals are due. Those repairs usually happen through the trim. Call the number on this page to be connected with a local plumber in Lewisville.
What Lewisville homes tend to have
Census survey figures put Lewisville's median build year at 1987, with about 35% of homes built before 1980. That points to a mix of two-handle compression valves in older houses and single-handle valves from the 1980s and 1990s in the subdivisions. Some of those earlier single-handle models were made before pressure balancing became standard, which matters if your shower lurches hot when someone flushes.
Most homes in town are on Winston-Salem/Forsyth County Utilities water, which the 2025 report describes as soft (average hardness 17.5 ppm) and disinfected with chlorine. Soft water leaves little scale, so stuck cartridges here are more often about worn seals than mineral buildup. Lewisville also has rural-zoned areas where public lines may not reach, and a home on a private well can see more grit reaching the valve.
Common valve types and how they fail
| Valve type | Typical failure | Usual fix |
|---|---|---|
| Two- or three-handle compression | Worn washers and seats cause drips; handles need force to close | New washers, seats or stems if available |
| Single-handle, no pressure balancing | Temperature jumps when other fixtures run | Cartridge swap, or a pressure-balancing valve if the body allows |
| Single-handle pressure-balancing | Spool wears, causing drift or weak hot | Replacement cartridge |
| Thermostatic | Sluggish response, often from wear or debris | Cartridge cleaning or replacement |
Signs your shower valve needs attention
- The showerhead keeps dripping once the water is off
- Full hot never gets truly hot
- The handle turns stiffly or wobbles on its stem
- The tub spout and showerhead both run when the diverter is pulled
- A water stain appears on a ceiling or wall near the bathroom
Timing notes
A slow drip can usually wait for a scheduled visit, though it wastes water and wears the seat further. A shower that won't shut off, or signs of water in the wall, should be handled sooner. Winter tends to reveal weak valves, because colder incoming water makes the shower lean harder on the hot side. Plumbing permits for Lewisville go through the joint Winston-Salem/Forsyth County Inspections Division if a valve replacement needs one. If the valve is being replaced and the wall is open anyway, ask about adding an access panel, which makes the next cartridge change much simpler.
