Brine Tank Asm. 15x17x36 Blue w/500 Air

The 15x17x36 Blue Brine Tank Assembly with 500 air check is a large-capacity salt tank for residential water softeners, built on a durable Nelsen polyethylene tank. Its wide square footprint holds a substantial salt charge, extending the interval between refills for busier households and higher-demand systems.

Air-check brining

The Fleck 500 air check is the functional heart of this configuration. As the brine refill finishes, it closes to keep air from being drawn into the resin tank, protecting the resin bed and supporting steady, predictable regeneration. With overfill timing handled by the softener's control valve through precise metering, the brine plumbing stays clean and simple, no separate float safety valve required.

The brine tank stores softener salt and dissolves it into the concentrated brine that recharges the resin during each cycle, the step that restores your system's ability to remove hardness minerals from the water. The 4" brine well, overflow elbow, and connecting tubing round out a complete, functioning brine system.

Maintenance stays simple even with the larger reservoir: keep the tank filled with quality salt, break up any bridging occasionally, and check the 500 air check during routine service. With its high capacity and economical air-check design, this Blue assembly is a practical, low-upkeep brine solution for systems whose valves meter the fill on their own. For value-minded high-capacity installs that rely on valve metering, it arrives ready to plumb in with everything matched and accounted for. Backed by durable Nelsen tank construction and a dependable Fleck 500 air check, it is a clean, capable setup for high-demand softeners that lean on the control valve for overfill timing.
