Dual Tank — City Water

Two tanks. Each one does one job, very well.

Splitting softening and carbon into their own tanks lets each medium work at full efficiency. The carbon tank backwashes on its own schedule to stay clean, and the softening tank carries enough capacity for big households.

Best for

Large homes and heavy water users who want maximum capacity and a carbon bed that backwashes itself clean.

What's included

  • Dedicated softening tank
  • Dedicated catalytic carbon tank with automatic backwash
  • Digital control valve
  • Brine tank
  • Professional installation

Specs

Capacity96,000 grains
Tanks2 media tanks + brine tank
RemovesHardness minerals, chlorine and chloramine taste and odor
Carbon maintenanceSelf-cleaning backwash

A great fit if you have…

  • Large homes, pools of guests, short-term rentals
  • High daily water use

Probably not the one if…

  • Smaller homes — the Softener + Filtration is plenty
