Specifications of the Fleck9100 SXT

The Fleck 9100SXT employs an advanced micro-processor based interface control as well as a Noryl valve body designed for home use. Fleck 9100 SXT design includes an up-flow backwash for efficient cleaning of water softener resin bed. This softener also features a twin tank duplex design with two rounded resin tanks made from high-quality poly-glass. A dual tank system uses 100 percent of the capacity of the in-service tank before switching to the other tank. The unit eradicates hard water and makes use of a soft water pre-rinse which flushes the resin of hardness.

Features of the Fleck 9100 sxt

As stated, the Fleck 9100 SXT water softener comes with twin water-softening tanks. The model empties one tank then switches to the other tank, saving water and salt. The tank regenerates and fills the large brine round tank with softened water, reducing the build-up of salt and keeping the resin cleaner. A safety float inside the tank prevents the unit from overfilling. Regeneration of resin is monitored by an on-demand flow meter, meaning it regenerates based upon the family’s water usage. A 48-hour internal capacitor offers power, so you don’t have to worry about missed cycles in the event of power outage.
