What hard water is doing to your house

Valley providers publish hardness from 8 grains per gallon to 25 g.p.g. depending on the city β€” and several municipals publish nothing at all. The photos below depict that hardness, working on your home, your investment, incrementally.

Your water heater is scaling and failing

Scale insulates the element, so the heater must burn more energy to do the same job and consequently fails years earlier than it should.

Glass and fixtures never look clean

That white film is hardness minerals left behind. And it comes back within days of every scrubbing.

Skin and hair feel stripped

Soap will not rinse clean in hard water. Normal skin feels itchy, rough and scaly. People with medical skin conditions have rashes. Your hair is dull and lifeless.

Pressure is dropping

Scale narrows pipe walls slowly enough that most people stop noticing until a fixture stops working.

Why people call us instead

We test before we quote

A number from your tap, read against the true average for your area. It is free, and you keep the results whether you buy or not.

Sized for your house

Grains per day, based on the people living there. An undersized softener regenerates nightly and still lets hard water through.

No script, no pressure

Nobody who comes to your house earns more by selling you more.

We will talk you out of things

If a salt-free unit is wrong for you, we say so. If your current softener is worth repairing, we say that too.

Where we work

From Buckeye to Queen Creek, and everywhere between. Pick your city for local water detail.

Phoenix

9.2–20.1 grains per gallon

Phoenix publishes a range of 9.2 to 20.1 grains per gallon β€” a spread of more than two to one across one city. So the city-wide figure tells you what Phoenix runs, not what your house runs. You want both numbers: the average for your part of the city, and a reading at your own tap. Two houses ten miles apart can genuinely want different equipment.

Scottsdale

16–25 grains per gallon

South Scottsdale has the hardest published water anywhere we work β€” up to 25 grains per gallon, half again what north Scottsdale sees. Two Scottsdale homes can genuinely need different equipment, which is why the address matters more here than in most of the valley.

Mesa

12–16 grains per gallon

Mesa publishes its hardness by zone β€” about 12 grains per gallon in the City Zone and about 16 in the Eastern and Southern Zones β€” and advises setting a softener to 16. Which side of the Eastern Canal you live on genuinely changes the equipment.

Chandler

5–20 grains per gallon

The high hardness combined with a lot of newer construction means Chandler homeowners often discover the problem through a failing water heater on a house that does not feel old enough to be failing.

Gilbert

8–10 grains per gallon

Gilbert has the softest published water in the valley, and it is the one place we regularly talk people down rather than up. Anyone quoting a Gilbert address off a valley-wide assumption of 18-grain water has not looked up the town’s own figure β€” and is sizing you for water you do not have.
