"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

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.

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.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

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.
