See if they have a dealer near you. You can go on just about any message board about water softeners and there are numerous people that have reported having 20+ years with their kinetico system and with very little routine maintenance. Google Kintetico VS (any brand water softener) see what people have to say. Nothing better than words from people that have owned different brands and what they think is the best.
