Ditto on the water filter, some of us have been known to use two. Hard water is bad stuff, leaves all that residue. When we purchased our water softener, we were doing a lot of surfing/researching. There is a map posted on several of the web sites that shows where the water is the most hard.
For those attending the fall Rally in Indiana, that chart shows the water as very hard (top rating). City water should be a bit better, the water at the Fairground is city water.
If you want to see the map, it is on this page, even though this happens to be the water softener we purchased, I am NOT promoting the unit/product, just the map.
Go to:
http://www.portablewatersoftener.com/ We love our water softener, but I have NO connection to the product or company.
ON EDIT: I went back and followed the map to what I believe is the original source, Morton Salts, see this web page,

Judy, let us know if you figure out where the water supply is and how to clean it, I think that would be great info for us all to know.
