"We are so happy we had The Water Doctors install our Kinetco water softener system in our Shelton Washington home. We put off having a water treatment system when the first company wanted over $8000 for a electric system. The Kinetco system is much less expensive and uses clean water to flush. We have noticed the significant difference already. Shane and one other installer arrived on time and took just about 3 1/2 hours to install with water being secured for only a few minutes. Shane did an awesome job explaining the system and how to take care of it. When all was done there was no mess and fresh clean water in our home."

Water Softeners FAQs, answered by experts

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.

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.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

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.

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.
