"Simply PUR recently installed a whole house water filtration/softening system, along with an RO system, in my home and did an amazing job. My experience with Vincent and his wife Claudia throughout the whole process was wonderful. They thoroughly explained the system, the installation process, and answered all my questions. The install went smooth, and Vincent even took care of a flawed plumbing trap previously done. What I appreciated most was how Vincent assured me he would continue to follow-up with me on when I should check my salt levels, change my filters, and if there are any updates with the equipment. I now have piece of mind knowing I'm providing clean and safe drinking water to my family. Thanks Simply PUR!!!"

"Jose and his team were super professional and very knowledgeable. Not to mention honest. Needed my whole house filter changed and ended up adding on a purified water system for drinking. The whole process was seamless. I would definitely recommend them to anyone looking for an honest and reliable company."

Water Softeners questions, answered by experts

Hard water doesn’t hurt, but it might feel more abrasive, especially if you have sensitive skin. It’s also about how your skin feels after bathing. You might feel as though you have a sticky film over your body because you do—it’s all that soapy residue left behind because the hard water can’t rinse it off completely.

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.

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.

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.
