Dual Tank: City Water

A softener plus a separate, self-cleaning carbon tank.

Best for: Large homes, high water use, or heavily chlorinated water

Two tanks, two jobs. One softens, the other is a dedicated carbon filter that backwashes itself, giving it more carbon and longer contact time for chlorine, chloramine, and disinfection byproducts.

Dedicated carbon tank with more contact time
Catalytic carbon option for chloramine
Self-cleaning backwash keeps the carbon flowing
Soft water for the whole home

How it works

Step by step

Carbon tank
A full tank of carbon reduces chlorine, chloramine, and disinfection byproducts, and backwashes itself on a schedule.
Softener tank
Resin removes the hardness minerals that cause scale.
Automatic regeneration
Each valve cleans and recharges its own tank automatically.
