The problem

Hard water works against your home, quietly.

Dissolved minerals leave scale inside your water heater and pipes, spot your glassware and shower doors, and leave soap unable to lather. It is invisible, gradual, and expensive over time. Measuring it is the first step to being done with it.

Built on data, not averages

The West Valley's water isn't one number.

Published hardness figures vary by city and by zone across the West Valley — Glendale reads harder than Peoria, and Surprise varies within its own limits. That is why we lead with a lookup and finish with a measurement at your tap, instead of quoting you a citywide average.

Answers

West Valley water questions

How hard is the water in the Phoenix West Valley?

Very hard. Arizona has some of the hardest water in the country, and West Valley cities generally fall in the 14–23 grains-per-gallon range. Published figures vary by city and by zone — Glendale reads around 14.6 gpg, Peoria around 9.7, and much of Surprise, Goodyear and Buckeye sits in the very-hard band. The reliable number is the one measured at your own tap.

Are water softeners banned in Arizona?

No. There is no Arizona ban on salt-based water softeners — the 'banned' claims come from sites marketing salt-free alternatives. Salt-based softeners are legal and common across Arizona, including the West Valley. A handful of California cities restrict them; Arizona does not.

My new build has a softener loop pre-plumbed. What goes there?

That loop is designed for exactly this. The Diamond Soft 30K softener (or the softener-plus-filter combo) connects to a standard Arizona softener loop, so installation in most West Valley new builds is clean and quick.

What does a water softener cost in the West Valley?

The Diamond Soft 30,000-grain softener is $6,250 installed, the whole-home softener + filter is $9,997, and the Black Diamond carbon filter is $6,150. Every price is published, and financing is available.
