(2) Water Right Santizer Plus water conditioners models ASP1-1044. Listing for $650 per unit. Both were installed new in March 2017 in the same house so overall load on each unit was low. They were used until September 2018. Both units work great and are in excellent condition. Rated for hardness up to 20 GPG. We are selling because we installed a new water system in the house with R/O. Located near Hays.
