Why Water Heaters Fail Early in Arizona

Nationally, tank water heaters last 12–15 years. In the Phoenix area, many fail in 8–10. Two main factors are to blame.

Sediment from hard water

Minerals settle in the tank, creating a layer that the burner has to heat through. This overheats the tank bottom and accelerates corrosion.

Extreme garage heat

Garages can reach 120–130°F in summer. That raises pressure in the tank and stresses the relief valve, gas controls, and electronics.

How to extend its life

• Flush the tank once a year
• Replace the anode rod every 3–5 years
• Install an expansion tank if you have a PRV
• Add a water softener
