NWS15PL 300K Twin Alt System w/3050 BT

At the top of the composite-valve twin-alternating range, the NWS15PL 300K Twin Alternating system from Nelsen Water Solutions delivers maximum capacity with uninterrupted soft-water service. Two 300,000-grain NWS15PL time-clock systems alternate so that one tank regenerates while the other stays online, an ideal match for the largest residential and light-commercial demands.

Maximum capacity meets composite durability

The 1-1/2" composite valve construction stands up to corrosion and chemical attack better than metal in aggressive or chlorinated water, an advantage that pays dividends over years of high-volume service. A composite electronic meter measures actual usage so regeneration happens on demand, conserving salt and water even at this large scale, while the Nelsen 1-1/2" MAV (Motorized Alternating Valve) automates the changeover between tanks. The result is always-on softening with the longevity benefits that composite materials bring to demanding water conditions.

• Two 300,000-grain NWS15PL tanks, twin alternating configuration
• 1-1/2" composite (plastic) valve bodies, corrosion resistant
• 1-1/2" composite electronic meter for demand-based regen
• Nelsen 1-1/2" MAV (Motorized Alternating Valve) for automatic switchover
• 30x50 commercial brine tank included
• Brine tank with Nelsen 484 safety valve, air check, overflow elbow, 5" brine well and cap

The system ships with a large 30x50 commercial brine tank equipped with a Nelsen 484 commercial safety valve, an air check, an overflow elbow, and a 5" brine well with cap, providing generous salt storage to match its capacity. Correct sizing against your measured hardness and peak flow, along with regular salt maintenance, keeps both tanks performing at full output. For the most demanding applications that require continuous, large-volume soft water with the durability of composite valves, this Nelsen NWS15PL 300K twin-alternating system is engineered to keep up.

Sizing a softener correctly avoids two common pitfalls: an undersized unit that regenerates too often and runs out of soft water during peak demand, and an oversized one that regenerates so seldom the resin bed can foul. Calculating capacity from your measured hardness and daily consumption lands you in the efficient middle ground. With the right size and routine salt maintenance, this Nelsen system delivers consistent soft water while keeping operating costs in check.
