"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"After speaking with Kevin (CEO) about the merits of the One Water System, and my own online followup, I bit, and was scheduled for installation 5 days later. Juan, the installer was on time, courteous, self-effacing, humorous, knowledgable and highly skilled. He replaced the ugly functioning plumbing (piping) with a more contoured professional appearance. After the system instalation, function test, old water softener packed and area cleaned. I was given an outline of positives results to look for.  And, as of 2 weeks after installation, I am very pleased with results. Faucet run faster, wife says hair and skin feels better. Good professional results from beginning to end.

Water Softeners questions, 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. 

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

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.

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.
