Spoiler: Yes. And your home can feel it.
If you’ve noticed white spots on your dishes, stiff laundry, dry skin, or appliances breaking down faster than expected, you’re probably dealing with hard water. And you’re not alone. San Antonio has some of the hardest water in the entire country.
Let’s break down why that matters and what you can do about it.
What Is Hard Water?
Hard water is water that’s packed with dissolved minerals, mostly calcium and magnesium. These minerals aren’t dangerous to drink, but over time, they leave behind a trail of damage. They build up inside your pipes, appliances, and fixtures, and they’re not easy to rinse off your skin, hair, or dishes.
In San Antonio, water hardness often ranges between 15 to 22 grains per gallon, putting it well into the “very hard” category. For comparison, anything over 10 is already considered extreme.
How Hard Water Affects Your Home
If you live in San Antonio, chances are your water is:
Wearing down your appliances faster
Clogging pipes and fixtures with mineral deposits
Leaving behind white spots on your dishes and faucets
Drying out your skin and hair
Fading and stiffening your laundry
It’s the kind of damage you don’t always see until it’s already costing you.
Why San Antonio Water Is So Hard
The answer is underground.
San Antonio’s water comes primarily from the Edwards Aquifer, a limestone-heavy source that naturally contains high levels of calcium and magnesium. As the water moves through the rock, it collects these minerals. By the time it reaches your faucet, it’s already extremely hard.
This is a regional issue. Whether you're in Alamo Ranch, Stone Oak, Leon Valley, or just outside the loop, your water likely needs softening.
What’s the Solution?
The most effective fix is installing a water softener system. A water softener removes calcium and magnesium from your water before it flows through the rest of your home. The result is water that feels better, cleans better, and protects everything it touches.
With a properly installed softener, you’ll see:
Longer appliance life
Better water pressure
No more spots or streaks
Softer laundry
Healthier skin and hair
