Avondale's municipal water supply carries high levels of calcium and magnesium — among the highest mineral concentrations in the Valley. That hard water takes a specific toll on water heaters:
Minerals settle to the bottom of the tank and form a layer of sediment that bakes on over time. The burner or heating element has to work harder to heat water through that insulating layer — which raises energy costs, creates the rumbling sound, and accelerates wear on the unit. Combined with Arizona's year-round demand and extreme summer heat, Avondale water heaters often fail earlier than their rated lifespan.
Annual flushing significantly reduces buildup. Pairing a new or repaired water heater with a water softener protects it further and can extend the life of all your plumbing.
