I had a working softener in my rural house that was working OK on well water, and thought it would work great on city water in town. Well I hooked it up and the water is very rusty. It clears after a while, and then gets rusty after it sits for a while. I think I should flush the thing out and try to run some cleaners thought it. I have it on bypass and the little missus is not happy at her lack of soft water.

Is it toast? Thoughts?
