"Both the salesman and the tech were fantastic. From explaining the benefits and the cost, to installing and actually making the plumbing system better, they did a fantastic job. The technician had some health issues he needed to see a doctor about, but he and the salesman returned later the same day and finished up the job perfectly. I can’t recommend them more. Oh, and our water is so much better now!"

Water Softeners questions, answered by experts

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

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.

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits 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 tools like Angi’s state licensing tool to verify an installer's license status.

Choosing involves understanding water hardness levels, household size, desired features, and consulting professionals experienced in suitable system types.
