"Its been six months since Aquarius Home Services installed our water softening and reverse osmosis sytems. We love having soft water for washing and bathing and knowing that our drinking water is safe to drink. As part the followup purchase contract Aquarius provides, today our technician, Nick Knapper, tested all the equipment to ensure everything was running properly. He answered all my questions, changed filters, filled the salt tank, and left additional salt. I couldn't have asked for more prompt, courteous, and reliable service. Thank you, Nick and Aquarius Home Services!"

Water Softeners FAQs, answered by experts

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.

It’s unlikely that hard water on its own could cause substantial hair loss or damage, though it’s true that bathing in hard water can cause your scalp to feel itchy or flaky and might dull your hair’s natural shine. Using high-quality shampoo and conditioner or buying a whole-home water softener can decrease these issues.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.

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.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.
