The house came with a rebuilt Water Refining System softener installed in 1999. Water Refining went out of business over 30 years ago. I know because I worked there for a year in 1971. We purchased a pretty expensive filtration system that 3 years ago that works extremely well for taking out iron, calcium, and hydrogen sulfate. At the same time we also purchased a reverse osmosis drinking water set up. The water tastes good, has no smell, no deposits, and makes an excellent pot of coffee. But that's just not soft water. Soft water has to come from a water softener. We just need a basic good quality water softener. I did a hard search tonight and ordered one of these. This kept coming up at the top of the list regardless of price.
