Aqua Twin 9100 Water Softener

i bought the 9100 a couple months ago, and i must say it works perfectly. it recycles every 700 gallons - this could happen at any time of the day. it only softens the exact amount of water you need so NO salt is wasted. i use half the salt i once use. every 700 gallons it switches tanks giving you an endless supply of softened water. i paid about $1600 that included installation. 40 lbs of salt use to last me one week now it last me two weeks. its half the price of a konetico - plus the electricity it uses is like $3.- a year - so dont let kenetico talk you into an non electric one because it cost less to run.
