Twin Tank Water Softener

With the Franklin Water Treatment electronic twin-tank softener system, businesses/homes benefit from soft water 24 hours a day, seven days a week. If your demand for soft water suddenly spikes, the second tank of softened water is there as a backup, with an innovative quick connection for seamless switching between the tanks. Why is soft water so critical in the first place? Hard minerals in the water can clog plumbing lines, negatively affecting product taste and/or performance. Without soft water, more soap and other additives are required to achieve desired results, and stains and mineral residue are common.

  • Residential/light commercial
  • Twin tanks provide continuous soft water
  • 15% savings in both water and salt
  • Only pennies per day to operate


Water Softening Process

Hard water enters the tank in service. As it passes through the resin, the hard water ions are attracted to the resin. By the time the water gets to the bottom of the tank, it’s soft.


Regeneration Process

When the resin becomes saturated with hard water ions, the tank goes into regeneration. Brine water is injected into the tank and rinses the hard water ions off the resin and down the drain. Once the resin is free of the hard water ions, fresh, soft water rinses all the brine out, leaving the tank ready for service.
