"This companies service department was great. Sales department wasn’t very thorough so the initial install had to be rescheduled but Joe from service was very personable and finished my fairly complex water softener install in 2 hours and it looks great. He also helped guide me in some other plumbing projects I was DIYing and recommended some other contractors for repairs needed around my home."

Water Softeners questions, answered by experts

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

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.

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. 

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

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.
