You truly don't realize how bad Vegas water is until you put a quality system in. We got the Kinetico Premier Series along with the K5 Drinking Water Station. Before we got the system our brand new appliance had so much hard water build-up that only after 6 months of use we had to have parts replaced because of the damage. After only 2 months with the system other appliances started working like new again and no hard water build-up was present. After drink from the K5 station, I don't even like drinking bottled water anymore. I can truly taste the difference.
