I have a water softener from US Water Systems, and the TDS is 200. Before it
is treated, it is at 500. The RO system reads a TDS of 14. I live in New
Mexico, and I know certain areas are higher than others. Salt is picked up by
the TDS, but I don't think it should be higher than the non-treated water.
Look up US Water Systems and you can call the people there with any questions.
I am very happy with my system. I use salt, not potassium in my water
softener, and I'm not sure if potassium makes a higher TDS rating.
