"The sales rep took several water testsâ ¦ The sales rep took several water tests and showed me the results. She told me that I needed more than just a water softener. I also needed a system to address the rust and iron in my well water. I did not want to spend a fortune but the sales lady was pretty convincing. The price was good and the workmanship was excellent. My water is clean again ! Now I can tackle the original problem. My toilet has bad rust stains. I will either get it clean, or replace it. I could not do this until the water was fixed."
