Before you replace it in Concord
Our published rule applies here exactly as it does in Charlotte, and it is the same rule whoever answers the phone:
- Under 8 years old: we repair it. Elements, thermostats, gas valves and dip tubes are serviceable parts on a tank with years left in it.
- 8 to 12 years old: we repair it if the fix lands under about $500. You are risking $250 to defer $2,000.
- Leaking from the tank body, at any age: replace it. A perforated tank cannot be patched.
What decides which of those you are in is partly the water. Yours comes from the City of Concord, and that is the supply whose chemistry has been working on the inside of your tank for its whole life. Where the water is soft and lightly buffered it corrodes rather than scales, which means tanks end by anode depletion and perforation rather than a slow decline. A leak from the shell is a genuine end-of-life signal here rather than something to nurse along.

What Concord itself changes
The housing in Concord
Concord is the best fit in the whole region for the cohort that is failing right now. The median home here was built in 1998 and 46.9% of the housing stock went up in 2000 or later, which means an enormous number of properties are on their second water heater and reaching the end of it at roughly the same time. Owner-occupancy runs 65.2% and median household income is $86,921, so these are households making the repair-or-replace decision on their own account rather than through a landlord.
The pipe era
With a median build year of 1998, Concord sits right at the end of the polybutylene window. Homes built before 1997 in the older subdivisions may still have grey polybutylene supply; anything from the 2000s onward is almost certainly copper or PEX. Polybutylene fails by sudden bursting rather than gradual flow loss, so it is a planning question rather than an explanation for weak hot water.
