Arizona hard water and water heater lifespan
Water in San Tan Valley and the wider Phoenix metro is extremely hard, commonly measuring 10 to 25 grains per gallon. Every gallon heated leaves calcium and magnesium behind, and that scale settles on the bottom of the tank and on the burner or heating element.
The result is that standard tank water heaters in Arizona commonly fail in 6 to 10 years, noticeably faster than the national average of 12 to 15 years. Scale insulates the heat source, so the unit works harder, runs longer, and stresses the tank lining until it leaks.
Two things move that timeline. Flushing the tank once a year, and replacing the anode rod around year five, buys back several years for a small cost. A tankless unit avoids the standing tank entirely and usually lasts longer here, though it needs its own descaling service on a hard water supply and costs more up front. If you also run a water softener, expect the longer end of every lifespan range on this page.
