Nelsen 150,000 Grain Twin-Tank Commercial (NWS15PL) Water Softener

Capacity and corrosion resistance come together in the NWS15PL 150K Twin Alternating system from Nelsen Water Solutions. Two 150,000-grain NWS15PL time-clock systems alternate service so soft water flows continuously, one tank regenerates while the other stays online, all managed through lightweight 1-1/2" composite valves built for demanding water conditions.

Composite durability, metered control

The composite valve construction resists the corrosion and chemical attack that can affect metal components in aggressive or heavily chlorinated water, making it a durable choice for challenging supplies. A 1-1/2" composite electronic meter monitors actual water use so regeneration is demand-based, conserving salt and water, while the Nelsen 1-1/2" MAV (Motorized Alternating Valve) automatically handles the switch between tanks. The combination delivers uninterrupted soft water with the long-term reliability that composite materials offer over brass in harsh conditions.

• Two 150,000-grain NWS15PL tanks, twin alternating layout
• 1-1/2" composite (plastic) valve bodies for corrosion resistance
• 1-1/2" composite electronic meter for usage-based regen
• Nelsen 1-1/2" MAV (Motorized Alternating Valve) for automatic switchover
• 24x50 commercial brine tank included
• Brine tank with Nelsen 484 safety valve, air check, overflow elbow, 5" brine well and cap

A 24x50 commercial brine tank is included, equipped with a Nelsen 484 commercial safety valve, an air check, an overflow elbow, and a 5" brine well with cap, so the salt-storage side arrives ready to go. As with any twin-alternating system, matching the 150,000-grain capacity to your measured hardness and peak demand ensures the best performance, and routine salt refills keep both tanks ready to deliver. For larger homes seeking uninterrupted soft water with the longevity of composite valves, this Nelsen NWS15PL 150K system is a dependable, corrosion-resistant solution that stands up to demanding water.

Proper installation pairs the system with a bypass so the unit can be isolated for service without shutting off water to the home, and locates it ahead of the water heater to protect that appliance from scale. A nearby drain for regeneration discharge and a grounded outlet for the control are also required. As with any softener, a recent water analysis covering hardness, iron, and pH ensures the system is set up correctly for your specific supply from day one.
