Where leaks show up in Mint Hill
Where the unit sits decides how urgent a leak is, and in Mint Hill that is not uniform. Garage and crawlspace both common, reflecting the two build waves. The 1970s and 1980s stock frequently has tighter access than the newer subdivisions, and we price that before the visit.
That matters more than the leak itself. Water escaping from a unit in a garage is an inconvenience. The same leak from an attic or an upper-floor closet is a ceiling, and it is the one case where we would rather you shut the cold inlet and call than wait for the morning rate.
- From the tank body: the unit is finished. A perforated shell cannot be patched, and anyone who says otherwise is selling you a delay.
- From the relief valve discharge: usually pressure rather than a failed valve. Put a gauge on a hose bib before replacing anything.
- From a fitting or connector: genuinely repairable, and frequently a $150 to $300 job rather than a replacement.
- Pooling with no obvious source: often condensate or the pan drain rather than the heater, which is worth establishing before anyone quotes you a tank.

What Mint Hill itself changes
The housing in Mint Hill
Mint Hill is an old farming town with two distinct housing waves rather than one. The 2000s are the single biggest decade at 22.0%, but the 1970s and 1980s together account for 35.0%, which is a larger share and gives Mint Hill the largest 1970s cohort of anywhere in this study. Those older homes are on their third or fourth water heater, and they are the ones where nobody has ever checked an anode rod.
The pipe era
A genuine polybutylene layer in the 1978 to 1997 portion, which is substantial here. Copper in the 1960s and 1970s stock. PEX in the 2000s builds.
