The Hidden Cost of Phoenix Tap Water
If you live in the Phoenix Valley, you are likely no stranger to water that tastes a bit off or leaves a white, chalky residue on your faucets. But the water quality in our area is more than just a minor annoyance—it’s actively impacting your home’s plumbing infrastructure, your appliances, and even your skin.
Here at ASA Plumbing, we frequently get calls for failing water heaters, clogged showerheads, and leaking pipes that all share one root cause: untreated local tap water. Here is why investing in a whole-home water treatment system is one of the smartest upgrades an Arizona homeowner can make.

1. Phoenix Water is Notoriously “Hard”
Water hardness is measured in grains per gallon (GPG). Anything over 7 GPG is considered hard. In the Phoenix area, water hardness routinely sits between 12 and 22 GPG, classifying it as “extremely hard.” This water is packed with calcium and magnesium.
When hard water flows through your pipes and is heated in your water heater, those minerals precipitate out and form scale. Over time, this calcification buildup:
- Clogs your plumbing, reducing water pressure.
- Destroys the internal heating elements of your water heater.
- Ruins the rubber seals in your faucets and toilets, leading to leaks.

2. High Chlorine Levels
To keep the municipal water supply safe from bacteria, local treatment plants use chlorine. In fact, the Phoenix Valley has enough chlorine in its tap water to treat a swimming pool. While it makes the water safe to drink, high chlorine levels dry out your skin and hair, fade your laundry, and give your tap water a harsh, chemical taste. A proper carbon filtration system removes this chlorine before it ever exits your taps.

3. Protecting Your Investment
Think about what you spend on plumbing fixtures, a new water heater, dishwashers, and washing machines. Running hard, chlorinated water through them reduces their lifespan by up to 30%. A water softener combined with a whole-home filter protects these investments, meaning fewer repair calls and premature replacements.
