I have used this unit for 2 or 3 years and have decided to go to a liquidadator. Our water supply is very high in calcium and is a constant problem. System was working when removed last year, probably will need to replace the salt cell. The 50.00 is to cover shipping, if you live in the Merced area you can just pick it up. No gaurentee. photo at P7122160_zpsceu1e1vh.jpg Photo by james-l | Photobucket
