"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."

"I have very hard water and wanted a unit installed. I called Ecowater Northwest because they were local and had excellent ratings on Angie's List. Aaron came to my house, answered all my questions, tested my water and recommended the two units I had installed. Dave did the installing and did an excellent job. I am very happy with the results and would recommend them to anybody that needs this type of service."

Water Softeners FAQs, answered by experts

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.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

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.
