21 Years of Service β And It Showed Us Why Water Heaters Don't Last Forever β³π₯
Ran a service call this week on a water heater installed back on 5-20-05. Twenty-one years of faithful service! But all that time finally caught up with it, and it started leaking from the tank β a clear sign the inner tank had corroded through.
Once a tank starts leaking, there's no repairing it. Replacement is the only safe option.
Why water heaters don't last forever:
π§ Sediment Buildup β Minerals in the water settle at the bottom of the tank over time, causing the steel to corrode from the inside out.
π§ Anode Rod Depletion β This "sacrificial" rod attracts corrosive elements so the tank doesn't have to. Once it's fully depleted (usually years before the tank fails), the tank itself starts corroding.
π§ Constant Expansion & Contraction β Years of heating and cooling cycles stress the tank's metal, especially around weld points.
π§ Water Quality β Hard water and mineral content (something we deal with a lot here in North Texas) speeds up wear on the tank and components.
The average lifespan of a conventional water heater is 8-12 years. This unit doubled that expectancy β a great run, but a great reminder that no tank lasts forever. If yours is pushing 15-20+ years, it's not a matter of if it will fail, but when β and usually it happens at the worst possible time.
We got this homeowner set up with a brand new unit and total peace of mind. If your water heater is getting up there in age, don't wait for a leak to force the issue β give us a call for an inspection.
