There are reasons why water softeners are made and marketed. Once in a great while you come across someone who learns this the hard way. Here in Washington County Wisconsin, in the village of Colgate this is exactly what happened.
A man bought a property that has no municipal water service, the water came from a well in the back yard. The home had new faucets and a new boiler that the previous owner just installed to boost the value of the home for the next owner. After buying the home, the man was pleased with how warm it was in the winter and had no complaints about his running water at first because everything was operating as if it were brand new.
