"Very impressed with the professional appearance and demeanor of the installers. They initiated a series of pre install checks around the home that solved some issues and found a few problems that needed to be solved before they started. On top of going the extra mile, the install was successful and I'm a very satisfied customer. The manager was responsive and accommodating. Highly recommend Dunn One Hour Plumbing, Heating and Air Conditioning."

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

"Nick G. Is professional, punctual and friendly. I had a leak coming from the kitchen sink and draining to my basement. This leak would have rotted the floor and caused considerable damage. Upon discovering this , I contacted my son, Clint Ehman, an electrician for Hoffman, to get a referral . Nick G. came out today, diagnosed the problem and fixed it. Nick fixed the problem and made my day so much better. The cost was fair and the work he did is exceptional. A shout out to a job well done. We will recommend Nick G. to family and friends."

"Mayo Plumbing is different from all the rest. They use data and research to inform their work. Before calling Mayo I had two different plumbers look at our new (very old) house. The first said, "St. Louis has hard water - you NEED a water softener." The second said, "St. Louis has great water - you DO NOT need a water softener." Mayo said, "What did the test results say? No one can tell you you need a water softener without testing your water first." BINGO. They tested our water and determined we DO NOT need a water softener. Same approach for our broken shower. The mayo plumber actually researched the issue, spending time with the paperwork and on the phone with the Kohler rep to determine exactly what we need to do, before making a wild guess and upselling us. I've never seen a plumber like this - these guys are SMART and will be our go-to provider!"

Water Softeners FAQs, answered by experts

Water purifiers and water softeners serve different purposes, so the best one will depend on your particular needs. Water purifiers remove contaminants from water (such as bacteria, viruses, and chemicals), leaving you with ultra-clean and safe water. However, water softeners remove minerals from your water so that the water doesn’t leave stains around your house or cause plumbing problems.

Selecting the right system depends on testing your water to understand the contaminants present and considering your household's water usage and specific needs, such as removing specific contaminants.

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.

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 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.
