"Chris was one of several quotes we got. His was the most relatable and understandable. He was here installing within a week and the results were just what we needed. We love our new soft water and drinking water. Very affordable too."

"We were so fortunate to find American Plumbing and Sewer, LLC! We had a quote from someone selling water softeners for $12,000, and we thought, â there has to be another much less expensive option out there!â With Lannyâ s company we got a system of much higher quality that cost 1/4 of the other personâ s quote. Personable, reliable, honest and wonderful customer service are words that describe American Plumbing and Sewer."

"Pure Water beat the other contractors on price and what we received as a product. We couldn't be happier with the installation. We now have hot water on demand on the opposite side of the house where it could take 5 min of water running for the water to be hot. Pure Water also installed a water softener and now our hard water is soft! Patrick who did the install was professional, personable, picked up what little mess there was, explained everything once the install was complete. We are so pleased we have them on the hook for a fireplace gas line and will have several bathroom projects going forward. We could not recommend Pure Water Services more. Thank you"

"Honest and good work can be hard to come by. Jay will get the job done right for a very reasonable cost, and he is incredibly kind on top of all that. So far Compass plumbing has: split pipes in my en suite bathroom from a single to a double sink, moved water lines from the floor to the wall to accommodate a floating vanity, moved a toilet location in my basement, replaced a water pressure regulator that was causing water hammer, and fixed a leak coming from the line going to our fridge. Definitely my go-to plumber!"

"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon. An EXTREMELY short time compared to our last water heater issue. Highly recommend Heart and will use them from now on."

"I would highly recommend this company! My service pro was knowledgeable, friendly, and efficient! He took on an old, leaking, rusted water heater job that was not for the faint hearted. He problem solved every odd glitch that my older house threw at him. The whole experience was completely positive!"

Water Softeners FAQs, answered by experts

Routine maintenance involves recharging the resin bed with salt or potassium, cleaning components, and periodic inspection.

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.

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.

Water purifiers and water softeners serve different purposes, so the best one will depend on your particular needs. Water purifiers remove contaminants from water (such as bacteria, viruses, and chemicals), leaving you with ultra-clean and safe water. However, water softeners remove minerals from your water so that the water doesn’t leave stains around your house or cause plumbing problems.

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.
