EcoWater ECR 3702

EcoWater’s elite water softener system is our conditioner, which is offered in a two-tank design. It is highly recommended for either municipal or well water supplies.
    • HydroLink Plus® Wi-Fi and Smartphone App Monitoring – Wi-Fi enabled technology sends continuous and excessive water use, system error, low salt and service reminder alerts, including a water-to-drain sensing alert notifying you when an excessive amount of water is going to drain.
    • Highly Efficient Counter-Current Regeneration
    • Water Meter – Allowing for chemical feed dosing, flow switch operation and water use information.
    • Patented Electronics Digital Demand Module – Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.
    • High Quality Fit and Finish with Dampened Hinge Salt Cover
    • Multi-Wrap Fiberglass Reinforced Resin Tank – Durable tank liner will not deteriorate, rust, or corrode.
    • Full One-Inch Riser with Self-Cleaning Distributors – One-inch diameter for increased flow rates, which ensures that household demand is adequately met. Distributors exhibit excellent flow rates and are cleaned automatically by counter-current water pressure.
    • Patented Stratified Resin Bed – Layered mix of fine and standard size resin provides superior filtration and iron removal without sacrificing flow rate capability.
    • Washed Quartz Underbedding – Helps provide a cleaner, more thorough regeneration of the resin.
    • Automatic Salt-Level Detection and Tank Light – Simply add salt, no salt level setting required. Our integrated sensor will detect the salt level and alert you when the salt level is low.
    • Positive-Action Brine Valve – Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling.
