System Integration
The Watts OFPCOM combo pack is designed exclusively for the Watts OneFlow Plus System (OFPSYS), providing complete cartridge replacement in a single package. The radial flow cartridge captures sediment, rust, and particulates before water reaches the TAC media, while the TAC cartridge transforms dissolved hardness minerals into harmless microscopic crystals that remain suspended in water and won't form scale on fixtures, appliances, or plumbing. This salt-free approach to scale prevention requires no backwashing, no electricity, and no wastewater discharge, making it ideal for whole-home water conditioning in municipal or well water applications where traditional water softeners are restricted or impractical.
