210,000 Grain Metered Commercial (NWS15) Water Softener

For large households and light-commercial sites, the NWS15 210K Meter Mineral Tank System from Nelsen Water Solutions brings serious softening muscle, 210,000 grains of capacity driven by a high-flow 1-1/2" metered control valve. This single-tank system is designed to keep up with substantial daily water use while regenerating efficiently and giving you freedom over the brine-side configuration.

High capacity with metered efficiency

The system ships with the Nelsen Water Solutions 1-1/2" metered control valve, commercial distributors, a gravel support bed, and high-capacity resin sized to the 210,000-grain rating. Because regeneration is triggered by measured water consumption rather than a clock, the system avoids unnecessary regen cycles, saving salt and water while ensuring soft water is ready when you need it. The 1-1/2" valve provides the flow capacity that larger homes and light-commercial operations require without becoming a bottleneck.

• 210,000-grain softening capacity
• 1-1/2" lead-free brass metered control valve
• Commercial distributors, gravel bed, and high-capacity resin included
• Demand-initiated regeneration for efficient operation
• Brine tank ordered separately for tailored sizing
• Progressive Flow option: add CL-COM-34-12 cord and a CL-NHBP-15 bypass per valve

Selling the brine tank separately gives you the freedom to pick a salt-storage tank that matches your space and refill habits rather than a one-size bundle. For Progressive Flow configurations, Nelsen specifies one CL-COM-34-12 communication cord for the system plus one CL-NHBP-15 no-hard-water bypass per valve. As with any high-capacity softener, correct sizing against your water hardness and peak flow is essential to efficient operation, and regular salt maintenance keeps performance steady. For a powerful, efficient single-tank softener that can be configured to your site, this Nelsen 210K system delivers dependable, high-volume results.

Routine ownership is simple: keep the brine tank supplied with quality salt, periodically check for and break up any salt bridging, and occasionally verify that the metered control is regenerating at sensible intervals for your usage. The high-capacity resin and commercial-grade components in this Nelsen system are built for years of dependable service, and demand-initiated regeneration means the unit works efficiently rather than wasting salt and water on a rigid schedule. For installers building out a high-flow softening setup, the 1-1/2 inch valve and generous resin volume give this single-tank unit the muscle to keep up.
