7 Signs You Have Hard Water (and What to Do About It)

Hard water affects the majority of homes in the United States — and most people live with it for years without realizing it's the cause of their everyday annoyances. The good news: it's one of the easiest water problems to diagnose and fix. Here are seven telltale signs.

1. Spotty dishes and cloudy glassware

If your glasses come out of the dishwasher with white spots or a cloudy film, that's mineral residue left behind as hard water dries. No amount of rinse aid fully solves it.

2. Soap and shampoo won't lather

Hard water reacts with soap, reducing lather and leaving a sticky "soap scum." You end up using more product to get the same clean.

3. Dry skin and hair

That same soap scum clings to your skin and hair, leaving skin feeling tight and hair dull or filmy even right after a shower.

4. Scale on faucets and showerheads

Crusty white or greenish buildup around fixtures is mineral scale. It clogs showerhead nozzles and faucet aerators, weakening water flow.

5. Stiff, dingy laundry

Minerals trapped in fabric leave laundry feeling stiff and looking dull, and can shorten the life of your clothes.

6. Rising energy bills

Scale builds up inside your water heater, forcing it to work harder. Over time this reduces efficiency and can shorten the appliance's lifespan.

7. Frequent appliance repairs

Dishwashers, washing machines, ice makers, and coffee machines all suffer when scale accumulates in their small passages and valves.

How to know for sure

You can guess from the signs above, but a professional water test tells you precisely how hard your water is and whether other issues are present. Aquovia's free in-home water assessment does exactly that — and we'll only recommend a solution if your water actually needs one.
