Built for homes that demand consistent, high-performance water treatment, this twin tank system delivers uninterrupted soft water 24/7. Designed with two 10" x 54" mineral tanks and powered by the trusted Clack WS1 CC metered valve, it provides maximum efficiency, reliability, and long-term performance.
