Water quality and water heater care
Many Arizona water supplies are hard, but hardness varies by provider, source, and season. Minerals can leave scale in tank and tankless water heaters, which can reduce efficiency over time. How much that matters for your home depends on your water chemistry, the equipment, and how it is maintained.
- Check your water provider's current water quality report for the hardness at your address.
- Follow the manufacturer's instructions for flushing, descaling, and anode rod inspection.
- Ask a licensed plumber whether treatment or a different water heater type makes sense for your home.
