Water Softeners questions, answered by experts

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

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.
