Brine Tank Assy

The Nelsen 18" x 40" Round Black Brine Tank Assembly with a Nelsen 464 brine valve is a complete, taller-capacity reservoir designed for Nelsen-based softener systems. The added height boosts salt storage over a standard 18x33 tank, and the black polyethylene construction withstands constant salt and moisture exposure without cracking or degrading. As a factory-matched assembly, it removes the compatibility guesswork of pairing a tank and valve from separate sources.

At the heart of this assembly is the Nelsen 464 brine valve, a reliable safety float that controls the brine refill level and helps guard against overflow. Combined with the included overflow elbow, it keeps salt-water management dependable through every regeneration cycle, even after years of service. You get steady, predictable operation without the risk of mismatched components.

Package Contents

• Round black polyethylene brine tank with cover
• 4" brine well with cap
• Nelsen 464 brine valve assembly
• Brine overflow elbow and connecting tubing
• Taller 18x40 size for extra salt capacity

The taller 18x40 size is a practical upgrade for households that want fewer salt refills without increasing the tank's floor footprint. Matching your brine tank to your control valve brand, as with this Nelsen-ready unit, simplifies installation and prevents fitment problems down the road. The tank stores the softener salt that dissolves into the concentrated brine and recharges the resin bed during regeneration, the process that keeps your water soft and your plumbing free of scale. Maintain adequate salt above the water line, clear any salt bridging, and rinse out sediment periodically for best results. From Water Softener Plus on the trusted Nelsen platform, this black assembly is a dependable replacement for an aging or cracked brine tank.

It helps to understand how this fits into your overall system. In everyday operation, your softener draws brine from this tank only during regeneration, then refills it with metered water to dissolve fresh salt before the next cycle. Pairing the tank with quality pellet or solar salt minimizes mushing and bridging, while an occasional full clean-out, emptying the tank, rinsing the interior, and checking the float or air check, keeps draws strong and regenerations efficient for years.
