Nelsen 120,000 Grain Metered Commercial (NWS15PL) Water Softener

The NWS15PL 120K Meter Mineral Tank System from Nelsen Water Solutions delivers high-capacity, metered softening through a lightweight, corrosion-resistant 1-1/2" composite plastic control valve. Rated at 120,000 grains, this single-tank platform is a capable, efficient foundation for residential and light-commercial water softening, with the flexibility to configure the brine side to your installation.

Composite valve, metered efficiency

The system includes the Nelsen Water Solutions 1-1/2" composite plastic metered control valve with commercial distributors, a gravel support bed, and high-capacity resin. The composite valve body resists corrosion and chemical attack better than brass in aggressive or chlorinated water, making it a durable choice for difficult supplies, while metered operation triggers regeneration based on actual consumption to conserve salt and water. The 1-1/2" valve supports the higher flow rates that larger homes and light-commercial sites require.

• 120,000-grain softening capacity
• 1-1/2" composite (plastic) metered control valve
• Commercial distributors, gravel bed, and high-capacity resin included
• Demand-based regeneration for efficient salt and water use
• Brine tank ordered separately for sizing flexibility
• Progressive Flow option: add CL-COM-34-12 cord, CL15-QCXQC quick connect, and CL-NHBP-15 bypass per valve

Because the brine tank is ordered separately, you can match the salt-storage vessel to your space and preferences rather than accepting a bundled size. For Progressive Flow configurations, Nelsen specifies adding one CL-COM-34-12 communication cord for the system, one CL15-QCXQC quick-connect, and one CL-NHBP-15 no-hard-water bypass for each valve. Proper sizing against your measured hardness and daily demand, plus routine salt maintenance, keeps the unit running efficiently over the long run. For a high-capacity metered softener that combines the durability of a composite valve with a flexible brine setup, this Nelsen NWS15PL 120K system is an excellent, adaptable choice.

A water softener works by ion exchange: hardness minerals such as calcium and magnesium are swapped for sodium on the resin bed as water passes through, and the resin is later recharged with brine during regeneration. Softened water protects plumbing and water heaters from scale, improves the performance of soap and detergent, and leaves fixtures and glassware noticeably cleaner. Matching the system grain capacity to your household hardness and water use is the single biggest factor in efficient, trouble-free operation.
