When a Lewisville water heater leaks from the tank, delivers discolored water, or keeps breaking at an advanced age, replacement is usually the better choice. Permits go through the joint Winston-Salem/Forsyth County Inspections Division, which serves the town. Call the number on this page to be connected with a local plumber in Lewisville.
Lewisville conditions that matter
Lewisville's houses were mostly built from the 1970s through the 1990s, with a median year built of 1987 and about 35% from before 1980. Many homes are now on their second or third water heater, and the oldest ones may still have original shutoffs and supply lines that are due for replacement along with the tank.
The town is served by Winston-Salem/Forsyth County Utilities through an agreement with the City-County Utilities Commission. That water is soft, with a 2025 average hardness of 17.5 ppm, and is disinfected with chlorine, so mineral scale inside the tank is usually light. Not every part of town is on public lines, though, since Lewisville has a Rural Overlay, and homes on a private well may see different sediment and mineral levels.
Water heater permits in Lewisville go through the joint Winston-Salem/Forsyth County Inspections Division. Piedmont Natural Gas serves Forsyth County, although availability depends on the street.
Straight swap or upgrade?
| Approach | What it involves | Trade-offs |
|---|---|---|
| Like-for-like tank | Same fuel, size and spot as the old heater | Fastest and simplest, with code updates to pan, valves and venting |
| Larger tank | More gallons for a bigger household | Needs space and may need a bigger gas or electric supply |
| Tankless | Wall-mounted unit heating on demand | New venting and often a larger gas line |
| Heat pump tank | Electric unit that pulls heat from surrounding air | Needs room air and a condensate drain; cools the space around it |
When it's past saving
- A leak from the tank shell or a wet drain pan
- Rusty water from the hot side
- Repeated relief valve discharges
- Running out of hot water much sooner than you used to
- A heater past its tenth or twelfth birthday
Seasonal timing
Heaters in unheated garages or crawl spaces work hardest from December through February, and that's when tired units fail. Planning the replacement in a milder month lets you look at upgrade options without the pressure of cold showers, and gives the Inspections Division time to process the permit. If the current heater is already showing two or more of the signs above, lining up a quote now keeps you from choosing a replacement in a hurry.
