Brine Tank Asm. 18x33 Almond w/500 Air

The Nelsen 18" x 33" Round Almond Brine Tank Assembly with a Fleck 500 Air Check is a complete brine reservoir for residential softeners that draw brine through an air-check system. Constructed from durable polyethylene with an almond finish, the round 18x33 tank offers generous salt capacity and a footprint that suits most household installations. Everything ships together as a matched set, making this a quick, dependable replacement for an aging tank.

The Role of the Air Check

The Fleck 500 air check is the key component in this package. Installed in the brine line, it seals off air at the end of the brine draw, preventing air from being pulled into the resin tank. That protects the integrity of each cycle and helps avoid waterlogging or erratic regeneration behavior that can leave your water harder than it should be. It's a small part with an outsized effect on consistent softening.

This assembly is a clean choice for replacing an aging brine tank or completing a new softener build. Remember that the brine tank holds the salt that dissolves into the concentrated brine solution used to regenerate the resin bed and restore its hardness-removing capacity, so a sound, watertight tank matters for both performance and avoiding leaks. Keep yours efficient by maintaining salt above the water line, checking for salt bridging along the walls, and rinsing out sediment periodically. Offered by Water Softener Plus and built on the trusted Nelsen platform, this almond unit pairs with most standard residential softener control 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.
