Water Softeners questions, answered by experts

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.

Soft water is better for your hair. The minerals in hard water can dry out hair, make it brittle, and leave a film on the hair and scalp that may cause irritation. Hard water also doesn't rinse out shampoo and conditioner effectively, which can lead to product buildup that makes hair look dull and limp. You may also find you need to use more shampoo to get a good lather in hard water.

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.
