The water heater went out in the house I recently bought in Las Vegas. So I took a shower at my neighbor's house and found out that my water softener was not working either. I went to a Home Show and signed up for quotes for a new water softener from a lot of different companies. Since I have always lived in areas that had great water - I knew nothing about living with the terrible water we have in Las Vegas. Every company that came to my house confused me more.........until Kinetico!!! Kinetico did a complete water test in my house, explained how all the systems on the market work, and let me make the decision instead of pressuring me to buy what they wanted to sell me. I even bought the K5 reverse osmosis system which has the highest rating from Consumer Reports. I am very happy with the Kinetico systems I purchased. I love the fact that everything is guaranteed for 10 years and has very low maintenance.
