Brine Tank Asm. 15x17x36 Charcoal w/231

Designed for compact softener installations, the Nelsen 15" x 17" x 36" Charcoal Brine Tank Assembly delivers a complete, ready-to-plumb regeneration reservoir in a space-saving square footprint. The charcoal finish blends discreetly into utility rooms, garages, and basements, while the heavy-duty polyethylene construction shrugs off years of salt contact and humidity without cracking, rusting, or degrading. For homeowners and installers who want a turnkey replacement rather than a box of loose parts, this assembly takes the guesswork out of getting a water softener back online.

This package arrives fully outfitted so you spend less time sourcing components and more time finishing the job. At the heart of the assembly is a Fleck 2310 brine safety valve, which automatically halts brine fill to guard against overflow if a regeneration cycle runs long or a float sticks. The included brine pickup draws saturated brine cleanly into the control valve during the draw cycle, ensuring each regeneration delivers the salt dose your resin bed needs to recover its softening capacity.

What's Included

• Square polyethylene brine tank with secure-fitting cover
• 4" brine well with cap to house the safety valve and float assembly
• Fleck 2310 brine safety valve for dependable overflow protection
• Brine overflow elbow and connecting tubing
• Brine pickup for reliable, consistent brine draw

The 15x17x36 square shape is a popular choice where a round tank simply won't fit, making it ideal for closets, alcoves, and tight mechanical spaces beside a water heater or pressure tank. In an ion-exchange softener, the brine tank holds the salt that dissolves into the concentrated brine used to flush hardness minerals like calcium and magnesium from the resin bed. To keep regeneration consistent, periodically clean the brine well, break up any salt bridging along the walls, and confirm the safety float moves freely. Pair this Nelsen assembly from Water Softener Plus with a compatible Fleck or similar control valve and a quality softening resin to complete a dependable whole-home water softener setup.

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.
