Kenmore 350 Series Water Softener —
My city water hardness is @ 24. I bought this softner after I bought a dishwasher. The dishwasher would have been destroyed in less then a month if I did not install this.
The connections are plastic, so if you are a do it yourselfer, and not that confidant in your plumbing skills, you may want to be sure to get the flex hose for installation.
