This 18x33 blue brine tank assembly arrives ready to build a softener regeneration reservoir. Supplied by Nelsen Corp (part BT1833R-B474-GRID), the kit combines an 18-inch by 33-inch blue polyethylene brine cabinet with a 2400-series style brine valve and a support grid plate.

• Manufacturer: Nelsen Corp
• Part number: BT1833R-B474-GRID (alternate J7500)
• Tank size: 18" diameter x 33" tall

• Round cabinet-style tank for salt storage

A brine tank holds the salt and the saturated brine that a softener draws during each regeneration cycle. The included brine valve and safety float control fill and draw so the system pulls the correct brine volume and does not overflow onto the floor, while the grid plate lifts the salt off the tank bottom to promote clean brine formation and reduce salt bridging and mushing. The round 18x33 footprint fits many mid-size residential softeners and slots neatly into a garage or utility corner. Confirm the valve air-check setting, float height, and overflow position match your control valve's cycle and salt dose before commissioning. A solid choice for replacing a cracked cabinet or assembling a new softener from individual components.

Salt Storage That Does Its Part

This Blue Brine Tank Assembly, complete with the 474 safety float and a support grid, holds the salt that a water softener depends on to recharge its resin. During each regeneration the softener siphons brine from this tank and then refills it with fresh water, dissolving more salt for the cycle to come. The 474 float guards against overfilling and shuts the brine draw at the right moment, while the interior grid platform keeps the salt lifted so water can circulate underneath and dissolve it evenly rather than packing into a hard, useless crust at the bottom.

When a New Tank Makes Sense

Over time brine tanks develop familiar problems: bridged or mushed salt, a sticking float, or a cracked cabinet that seeps onto the floor. If your softener runs its cycles but the water stays hard, the culprit is often a failed float or a fouled tank rather than the valve itself. Replacing the tank as a complete assembly, float and grid included, clears out the accumulated grime and restores reliable brining in a single step. It is also a tidy upgrade when the rest of your system still has good years left.

Confirm and Install

Because the brine line and float link to your particular control valve, matching them matters. Send us your valve or system details and we will confirm this assembly fits before it ships. The tank comes with the float and grid it is designed around, we include whatever manuals we have on file, and the Water Softener Plus team can walk you through connecting the brine line and setting the float so the swap goes smoothly.
