We recently bought a home that was 11 years old and it never had a water softener in it. We recently purchased the Kinetico RO, dechlorinator and softener. Even though our home was not built for install of a softener, the installer found a way to make it work. YAY!! With every use of the water we can tell it is cleaning out the remains of hard water build up in the lines. Our hair and skin improves daily and shows the result of having the best water conditioner and softener available. In comparison to other systems we have had in the past we only wish we would have purchased this system many years ago. Our sales person Nancy explained everything in detail and made it a very easy decision. Thank you Kinetico!
