Water Softeners questions, answered by experts

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.

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.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

No, a water descaler won't descale pipes. The charged water running through the pipes may very slowly dissolve mineral deposits and hold them inside the water, but it's a very gradual process. If your pipes do need descaling, it's much better to get a local plumber to descale your pipes.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.
