Where leaks show up in Cornelius
Where the unit sits decides how urgent a leak is, and in Cornelius that is not uniform. Garage and closet installs across the subdivisions, with attic units in the larger lakefront and near-lake homes. Access is generally good.
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 Cornelius itself changes
The housing in Cornelius
Cornelius is a solid fit for second-cycle water heater work: 24.1% of the stock was built in the 1990s and 32.5% in the 2000s, giving a median build year of 2002. That is a large, consistent cohort of homes whose original units have already been replaced once and whose replacements are now aging out.
The pipe era
Copper and PEX through most of the stock, with polybutylene possible in the earlier 1990s portion. Supply pipework is rarely the cause of hot water complaints here.
