Culligan HE Cleer Plus water softener. Paid $2750 for it new in December of 2016 and only used for a little over a year. Asking $1100 or make offer. It has been used on well water and works fine; we are just going a different route with filters before the water gets to the softener so we don't need the softener to do as much as this one will.
