Stack Vortech

The Reliant Stack Vortech Water Conditioning System is a high-performance automatic water treatment solution designed to improve water quality while delivering efficient operation and long-lasting durability. Built with a 1” high-flow design and a premium ion exchange resin system, the Reliant Stack regenerates only when needed based on household water usage, helping reduce salt and water waste while maintaining consistent performance.

Engineered with corrosion-resistant components and a seamless fiberglass-wrapped resin tank, this system is designed for dependable long-term operation. The exclusive Media Exchange Module and Reliant “Total Control” valve provide efficient water conditioning with a single motor-driven piston operation for reliable performance and simplified maintenance.

Additional features include a full-flow bypass valve, double polishing backwash for enhanced media cleaning, enclosed circuit board protection, safety shut-off system, and a dry salt-grid brine system. The unit also includes a 3/4” John Guest elbow fitting kit for convenient installation.

Available in multiple media configurations, the Reliant Stack Vortech can be customized for specific water concerns including hardness reduction, chlorine reduction, chloramine reduction, hydrogen sulfide treatment, and limited iron reduction depending on water chemistry. Optional configurations and salt tank sizes are available to fit a variety of installation requirements, including outdoor applications with optional rain covers.
