"It was both informative and a pleasure to meet Vincent and learned about water purification for our home. Vincent did not "sell". He gave us information we needed to make our decision. The installation-scheduling and the installation itself went very smoothly. The system is a neat and compact layout. Once it was installed, Vincent patiently answered all our operational questions. Vincent is a very enthusiastic spokesman for water purification and an extremely friendly person. We look forward to having him service our system in the years to come."

"Jose and his team were super professional and very knowledgeable. Not to mention honest. Needed my whole house filter changed and ended up adding on a purified water system for drinking. The whole process was seamless. I would definitely recommend them to anyone looking for an honest and reliable company."

"The receptionist was courteous and personable when I called. The workers arrived promptly. They were professional and knowledgeable. They completed the work efficiently and promptly. I have used filtered water for over ten years. This was the first time I used this company and their prices were entirely reasonable. I have a water tester. And the new water filtering system they installed passed the test for excellent water filtration."

"James Stone was really good. We had a little confusion about the rebate for the original furnace they were going to install but we came to an agreement and I received half of the rebate due to me not being qualified for the full rebate. I was more than satisfied and they were very accommodating. Everything is working great. He went out of his way to make me satisfied. Thank you for giving me this company's information."

Water Softeners FAQs, answered by experts

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

It depends on the type of surface. For instance, if you’re trying to get rid of hard water deposits on glass, you can spray vinegar onto the surface and wipe it off with a soft cloth or non-abrasive sponge. However, if the deposits are on granite or natural stone, it’s better to use baking soda and water rather than vinegar or other acidic cleaners.

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.

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.

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.
