What Davidson 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 Charlotte Water, 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 Davidson itself changes
The housing in Davidson
Davidson is a college town with a genuinely old centre around the campus and a steady stream of newer building around it, some of it very recent. The older houses near the college have the problems old houses have: tight utility spaces, heaters fitted where there was room rather than where there should have been, and discharge pipes that were run before anyone was checking. The newer building is straightforward by comparison.
Where the heaters sit
Utility room, closet and crawlspace in the older centre. Garage and attic in the newer subdivisions. Attic installs are the ones we want to know about on the phone, because a leak in an attic is a different urgency from a leak in a garage.
