Water Softeners questions, answered by experts

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.

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.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

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.
