Plumbing in Phoenix: what locals should know
Water quality
The extremely hard water in Phoenix causes heavy scale buildup in pipes and appliances. Water heaters, dishwashers, and faucets all suffer. A water softener is practically a necessity here.
Freeze risk
Freezing is uncommon in Phoenix, but the risk isn't zero. During rare cold snaps, homes here are actually MORE vulnerable because plumbing isn't typically winterized. Keep pipe insulation on hand for outdoor runs.
Material recommendation
For Phoenix's hard water, PEX piping is ideal — it doesn't corrode or develop pinhole leaks like copper can in mineral-rich water. It's also the most cost-effective option for whole-house repiping.
Local tip
If your Phoenix home was built in the 1990s or later, your supply pipes are likely in good shape. The most common plumbing issues in newer homes here are water heater replacements and fixture upgrades.
