I called 3 different companies to get quotes on a water softener for our home. I talked to Hillary and she sent the warranty and info on their systems over right away. We ended up going with the softener with whole house filtration because it was the same price as the softener by itself from another company and they use the same brand of valve, and this system takes out the chlorine as well. The fleck valve is the best one as far as online reviews and the warranty is good through Sweetwater. Great experience over all and we love our system. Makes such a difference in AZ to have a water softener.
