Brine Tank Asm. 18x40 Black w/2300 S

The Nelsen 18" x 40" Round Black Brine Tank Assembly with a Fleck 2300 brine safety valve offers extra salt capacity in a sleek, dark finish. The taller 40-inch tank stores more softener salt than a standard 18x33 unit, making it a smart choice for higher-demand households that want fewer refills and a longer runtime between salt top-offs. As a complete, matched assembly, it installs quickly with no loose parts to source.

This configuration relies on the Fleck 2300 brine safety valve to protect against overflow, automatically halting brine fill once the proper level is reached. The result is dependable, worry-free regeneration backed by a trusted mechanical safeguard, which is especially reassuring in finished basements or living spaces where a salt-water spill would be costly.

Brine tanks are the engine of regeneration in an ion-exchange softener, holding the salt that dissolves into brine to recharge the resin bed so it keeps capturing calcium and magnesium, the minerals behind scale and spotting. A sound, leak-free tank is essential to that cycle and to keeping your softening consistent. To keep yours performing well, maintain salt above the water line, break up any salt bridging that forms, and rinse sediment from the base once or twice a year. The black finish gives it a clean, contemporary look in any utility space. From Water Softener Plus on the trusted Nelsen platform, this assembly is a dependable replacement or new-build choice compatible with most standard softener valves.

For a smooth installation and long service life, consider the following. Hard water leaves scale in pipes and water heaters, spots on glassware, and a filmy feel on skin and hair. This brine tank is a key part of the system that solves those problems, supplying the salt brine that keeps your resin working. With proper salt selection and routine checks, it supports reliable softening that protects appliances and improves the feel of every shower, load of laundry, and glass of water.
