Fleck - Model 9100 SXT - Twin-Alternating Metered Water Softener Brochure

Most water softeners have a single resin (softening) tank. That means that when it is time to regenerate (typically at 2AM or some other time when water usage is low), if you were to use water, it would be hard and not softened. The 9100SXT eliminates that issue. If you are a doctor, police office, EMT, funeral director, fireman, if you work a swing shift, or are just a night owl, then maybe you are a person who needs the benefits of having 24/7/365 soft water. The 9100SXT is especially efficient with big families or with water that contains iron.
