What Statesville water actually does to a tank
Maintenance advice is usually written for hard water, and most of this region does not have it. Your supply comes from the City of Statesville, and the question worth asking is not how much scale it leaves but how corrosive it is. Soft, lightly buffered water forms no protective film inside the tank lining, so the anode rod is doing the entire job of protecting the steel.
That inverts the standard advice. An annual flush matters less here than it would in a hard-water city, and the anode rod matters far more. A tank that has never had its anode checked at eight years old is running on whatever is left of it, and once that is gone the tank itself starts corroding.
- Anode inspection is the one job on this list that changes how long the tank lasts.
- A T&P test with a pressure reading, because a weeping relief valve is usually pressure rather than a failed valve.
- A flush, with an honest warning first: on a tank over about ten years that has never been flushed, the drain valve frequently will not reseat once opened.

What Statesville itself changes
The housing in Statesville
Statesville is the Iredell county seat and it has been a town since 1789, which shows in the housing. Three separate historic districts are on the National Register here: Academy Hill, built mainly between 1885 and 1930, South Race Street, and the Commercial district dating from about 1875 to 1925. Around that core sits a much newer ring of subdivision building. A water heater call in the historic district and a water heater call off the bypass are effectively two different jobs, and quoting them the same way is how people end up surprised.
Where the heaters sit
Crawlspace, basement-adjacent utility space and closet through the older neighbourhoods around downtown, Signal Hill and the Race Street area. Garage and attic in the newer building out towards West Iredell and Brookdale. Access is priced before the visit.
