Brine Tank Asm. 18x33 Blue w/PU

For a clean, no-frills brine tank upgrade, the Nelsen 18" x 33" Round Blue Brine Tank Assembly with Brine Pickup gives you exactly what's essential. The vivid blue polyethylene tank pairs long-lasting durability with a distinctive look, and the included brine pickup handles the core job of drawing brine into your softener's control valve during regeneration. It's an economical solution when your existing safety valve or air check is still in good shape and only the tank needs replacing.

This simple configuration is perfect when you already have a safety valve or air check on hand, or when your system design doesn't require one. The brine pickup draws the dissolved brine from the bottom of the tank during the draw cycle so the control valve can recharge the resin bed and restore its hardness-removing capacity, keeping your home free of scale and spotting.

The 18x33 round size is among the most common in residential softening, balancing generous salt storage with a footprint that fits most utility spaces and reduces how often you need to refill. The brine tank is central to ion-exchange softening, holding the salt that dissolves into brine to recharge the resin so it keeps capturing calcium and magnesium. To keep this tank performing reliably, maintain salt above the water line, break up any salt bridging that forms, and clean sediment from the base once or twice a year. Backed by Water Softener Plus and built on the trusted Nelsen platform, this blue assembly is a budget-friendly, dependable replacement for a worn or leaking brine tank.

A quick note on sizing and compatibility: Brine tanks like this one work hand in hand with the resin tank: while the resin captures hardness ions during normal service, the brine tank supplies the salt solution that strips those ions away during regeneration, returning the bed to full capacity. Sizing the tank to your salt-use habits and softener grain rating helps avoid frequent refills, and using clean, high-purity softener salt reduces sediment buildup while keeping the safety float and brine line clear.
