How Often Should You Service Your Water Heater in Arizona Hard Water?

In Arizona's hard water, you should flush your water heater at least once a year - and every six months if your water is especially hard or you use a lot of hot water. Regular maintenance clears the sediment that our hard water deposits, keeping the unit efficient, quieter, and longer-lasting. Here's a simple maintenance schedule for San Tan Valley homeowners.

• Flush the tank: at least once a year (every 6 months for very hard water).
• Check the anode rod: every 2-3 years - this sacrificial rod protects the tank from rust.
• Test the T&P (pressure relief) valve: once a year.
• Inspect for leaks and corrosion: a few times a year, especially around the base.
• Professional tune-up: once a year is a smart habit, particularly for older units.

Our hard water drops a lot of mineral sediment into the tank. Left alone, that layer makes the heater work harder, run louder (the popping sound you may hear), lose efficiency, and wear out years early. Annual flushing is the single best way to fight it.

• Popping or rumbling noises (sediment buildup).
• Rusty or discolored hot water.
• Running out of hot water faster than before.
• Water pooling around the base.

Some homeowners do, but it involves draining very hot water and working around gas or electrical parts and the relief valve. If you're not comfortable, a professional flush is inexpensive and includes a full inspection. Pairing maintenance with a water softener dramatically slows sediment buildup.
