NWS15PLM 210K Meter Mineral Tank System

When a standard residential softener simply cannot keep up, the Nelsen Water Solutions NWS15PLM 210K Meter Mineral Tank System steps in with 210,000 grains of capacity in a single mineral tank. Built around a 1-1/2" composite plastic metered control valve, this system tracks the gallons your household or facility actually consumes and triggers regeneration only when needed, keeping salt and water use in check. That demand-based intelligence is what separates a metered softener from a basic timer model, ensuring soft water during peak draw without wasting resources during slow periods.

• 210,000 grain softening capacity for large homes and light commercial use
• 1-1/2" composite metered Nelsen control valve resists corrosion
• Usage-based, demand-initiated regeneration
• Includes commercial distributors and a stabilizing gravel bed
• High-capacity ion exchange resin for reliable hardness removal
• Ships at roughly 620 lbs per system

The composite valve body is a notable advantage in this size class, offering durability without the weight or corrosion concerns of metal in continuous-duty service. Inside the tank, the gravel underbed supports even flow distribution while the high-capacity resin exchanges hardness ions for sodium, eliminating the scale that shortens the life of water heaters, dishwashers, and fixtures. The commercial distributors ensure water moves uniformly through the full depth of the resin bed, maximizing the contact that drives efficient softening.

The brine tank is ordered separately so you can size salt storage to your routine and reserve needs. For Progressive Flow Systems, plan for one CL-COM-34-12 communication cord per system, one CL15 quick connect x quick connect, and one CL-NHBP-15 no-hard-water bypass per valve. Soft water from a system this size pays dividends throughout a property, reducing detergent use, brightening laundry, protecting heating elements, and keeping fixtures free of crusty deposits. As part of the trusted Nelsen Water Solutions softener lineup offered by Water Softener Plus, the NWS15PLM 210K brings serious, dependable capacity to whole-house treatment in hard-water regions and other demanding applications.

Because the system ships as a mineral-tank assembly, plan your installation space and drain access ahead of time, and confirm your hardness reading so the metered valve can be programmed for optimal capacity. Well configured, the NWS15PLM 210K runs efficiently for years with little more than periodic salt refills in the separately ordered brine tank.
