How Hard Is Your Water?
Enter your ZIP, see where your neighborhood lands on the hardness scale and learn — in plain English — what those numbers mean for your home.
Check Water Hardness by ZIP Code
Type your ZIP and we’ll show you what the water in your area is doing to your home.
Your ZIP is in the Las Vegas Valley — and that means very hard water.
Nearly the entire Valley drinks from the same source: Lake Mead, fed by the Colorado River. So whether you’re in Summerlin, Henderson or North Las Vegas, your taps run around 16 grains per gallon — over half again past the point where the scale says “very hard.” The fix isn’t scrubbing harder; it’s treating the water where it enters your home.

The hardness scale below still applies anywhere in the country — your water utility publishes a yearly water quality report with your local number. And if you’re close to the Valley, give us a call; we may still be able to help.

What “Hardness” Actually Means
Hard water is simply water carrying dissolved rock — mostly calcium and magnesium it picked up flowing over and through mineral-rich ground. It’s measured in grains per gallon (GPG): one grain is about 17 milligrams of dissolved mineral in a gallon of water. Sounds tiny, until you multiply it by the hundreds of gallons a household runs every day.
Those minerals are harmless to drink — your body actually uses calcium and magnesium. The trouble starts when the water hits heat or evaporates: the minerals come out of solution and harden into scale, the white crust you see on faucets and shower glass. The same crust forms where you can’t see it — inside your water heater, dishwasher, washing machine and pipes.
Because roughly 90% of Southern Nevada’s water comes from Lake Mead, hardness here isn’t a neighborhood-by-neighborhood lottery — virtually every home in the Valley gets very hard water. The only real variable is how long it’s been working on your plumbing.
The hardness scale, decoded
-
Soft 0–3.5 GPG · 0–60 ppm
Soap lathers instantly, glasses dry spot-free. Usually means the water is already softened.
-
Moderately Hard 3.5–7 GPG · 60–120 ppm
The first spots show up on dishes and faucets. Skin starts feeling a little tight after showers.
-
Hard 7–10.5 GPG · 120–180 ppm
Visible white crust on fixtures and shower doors. Appliances start aging faster than they should.
-
Very Hard 10.5+ GPG · 180+ ppm
Heavy scale everywhere water touches. Water heaters, dishwashers and washing machines all take real damage.
Hard Water Questions
No — that’s the good news. Calcium and magnesium are minerals your body actually uses, and hard water is safe to drink. The problem is what it does to your home: scale in pipes and appliances, spots on everything and dry skin and hair. It’s a comfort-and-cost issue, not a safety one.
Softening an entire city’s supply would be enormously expensive, and much of that water goes to irrigation and industry that doesn’t need it. Utilities focus on making water safe; making it comfortable at home is a point-of-entry job — that’s what a softener at your house is for.
Essentially, yes. About 90% of Southern Nevada’s supply comes from Lake Mead, so Summerlin, Henderson, North Las Vegas and Boulder City all pull from the same mineral-rich source. A few pockets blend in groundwater, but nothing in the Valley tests below “hard.”
Our free water test measures hardness right at your kitchen tap in about 20 minutes — along with TDS and a low-level chlorine test. It’s the same measurement we use to size a system, and it’s free whether or not you ever buy anything.
For hardness, a properly sized whole-home softener is the gold standard — it removes the minerals before they reach your plumbing. If you’d rather skip salt entirely, a salt-free conditioner stops scale from sticking instead. We’ll recommend honestly based on your numbers.
