Cleveland runs its own water system fed by town wells, and since the report doesn't list hardness, a quick test is a good first step before putting in a tankless water heater. Rowan County Building Inspections handles the permit. Call the number on this page to be connected with a local plumber in Cleveland.

Local conditions in Cleveland
Cleveland is a small western Rowan County town on US 70, and it supplies its own water from three town-owned wells rather than the Yadkin River system that serves Salisbury. The 2025 water quality report shows chlorine disinfection at a low residual and no violations, but it does not report hardness. Groundwater can be harder than river water, so testing a sample from the kitchen tap tells the plumber how often a tankless unit should be flushed and whether a scale filter is worth adding. Homes outside town on private wells should test their own water.
The town's drinking water lines were replaced between 2008 and 2019, according to a 2021 case study, so the street side of the system is relatively new. Inside the house is another matter. Census survey figures put the median build year at 1982, with about 47% of homes built before 1980, and those older houses can have water heaters in tight closets with metal flues.
Piedmont Natural Gas serves only portions of Rowan County, per a state utilities commission report, so not every Cleveland house has a gas meter. Permits come from Rowan County Building Inspections, after zoning approval from the town; the county's February 2024 schedule lists a tankless water heater permit at $90.
Fuel options at a glance
| Fuel | Good fit when | Watch for |
|---|---|---|
| Natural gas | The house already has a Piedmont meter | Gas line size and a new sealed vent |
| Propane | No gas main, but a propane tank is on site or can be added | Tank, regulator and line sized for full burner demand |
| Electric | Smaller household with ample electrical service | Panel capacity and large dedicated circuits |
Signs your water heater needs attention
- Scale or white flakes in faucet aerators
- Hot water that cycles between hot and lukewarm
- A tank more than ten years old, or one leaking at the base
- A tankless unit with a recurring error code
Seasonal timing
Well water stays more even in temperature than surface water, but it still runs colder in winter, and a unit sized only for warm months may struggle then. Late summer and fall are practical times to plan a swap or schedule a flush before cold weather. If you smell gas, leave the house and call 911 or Piedmont Natural Gas at 800-752-7504 from outside.
