NWS20 210K Meter Mineral Tank System

The Nelsen Water Solutions NWS20 210K Meter Mineral Tank System brings substantial softening capacity to a single, space-efficient mineral tank. With 210,000 grains of capacity and a 2" lead-free brass metered control valve, it serves large homes and light commercial sites where demand is high and reliable scale control is essential. The metered valve keeps the system efficient by responding to your actual water use rather than running on a rigid schedule.

Metered efficiency

Rather than regenerating on a fixed schedule, the metered valve counts the gallons your property actually uses and regenerates only when the resin is exhausted. This demand-initiated operation cuts unnecessary cycles, saving salt and water while ensuring soft water is always on tap, even when usage spikes during busy mornings or peak production hours.

• 210,000 grain softening capacity in a single tank
• Nelsen 2" lead-free brass metered control valve
• Commercial distributors for even flow across the resin bed
• High-capacity resin seated on a gravel underbed
• Demand-based regeneration for lower operating costs
• Approximately 667 lbs weight

The 2-inch valve and commercial distributors give the system ample flow capacity, preventing the pressure drop that undersized equipment can cause in larger installations with many simultaneous draws. Inside, high-capacity resin exchanges calcium and magnesium for sodium, stopping scale before it can damage water heaters, appliances, and plumbing throughout the building. The supporting gravel bed beneath the resin promotes balanced flow and helps the bed resist channeling for consistent, long-term performance.

Order the brine tank separately to match your salt storage and reserve requirements. For Progressive Flow Systems, add one CL-COM-34-12 communication cord for the system and one CL-NHBP-20 no-hard-water bypass for each valve. Soft water from a system this size protects an entire property while cutting detergent use and brightening laundry. Part of the dependable Nelsen Water Solutions softener lineup from Water Softener Plus, the NWS20 210K is a strong choice for high-demand whole-house and light commercial softening.

When planning the install, confirm your hardness reading and daily usage so the metered valve can be set for the right capacity, and allow proper drain access. Once commissioned, the NWS20 210K regenerates automatically on real demand, quietly keeping a high-use home or light commercial site supplied with soft water and free of scale.
