What 9 gpg means in Chihuahua
At this level limescale builds up slowly but steadily. White traces appear on faucets and shower glass within months, and the water heater loses a little efficiency every year. Light protection already pays off.
What it does to your home
Water heater: even a thin layer of scale insulates the heating element and drives energy use up.
Appliances: dishwashers, washing machines and coffee makers scale up and fail years early.
Fixtures and skin: white spots on faucets and glass, dry skin and dull hair after every shower.

Frequently asked questions — Chihuahua
Is 9 gpg considered hard water?
On the US scale, 0–3.5 gpg is soft, 3.5–7 gpg moderately hard, 7–10.5 gpg hard and above 10.5 gpg very hard. At 9 gpg (154 ppm), water in Chihuahua is classified as Moderately hard water.
Does Chihuahua have a limescale problem?
Water in Chihuahua averages 9 gpg — Moderately hard water. The harder the water, the faster calcium carbonate deposits build up in water heaters, appliances and pipes. Below 3.5 gpg the risk is minimal; above 7 gpg scale becomes a running cost.
How do I find the exact water hardness at my address in Chihuahua?
Check your utility's annual water quality report (Consumer Confidence Report) or your water bill, or use our free interactive hardness map. Hardness can vary widely between neighboring utilities in Chihuahua.
Do I need a salt-based water softener at 9 gpg?
Not necessarily. Salt softeners add sodium to your water and need constant refills. LIMPEO treats limescale with an electromagnetic field — no salt, no chemicals, no maintenance — and keeps healthy minerals in your drinking water.
