Compared with a shorter cabinet, the extra 40-inch height increases salt-holding capacity so you refill less often, which is helpful for households that regenerate frequently or run a larger softener with a bigger salt dose. The brine valve and safety float meter each brine draw and shut off the refill at the set level to guard against an overflow. The neutral almond color blends into utility rooms, basements, and garages better than bright colors. Add a grid plate if your installation calls for elevated salt support and cleaner brine formation. Match the tank diameter, valve draw rate, and overflow height to your softener's control valve before putting it into service. Well suited as a direct replacement cabinet or as the brine side of a fresh softener build.

Where the Salt Lives

This Almond Brine Tank Assembly is the salt reservoir that keeps a water softener regenerating on schedule. Every time the softener cleans its resin, it draws a measured amount of brine from this tank, then refills it with fresh water to dissolve more salt for the next cycle. The included 474 safety float and brine well assembly manage that fill so the tank does not overflow and the softener draws clean brine rather than sediment from the very bottom. The almond cabinet suits a laundry area or garage and gives you plenty of room to keep the salt topped up.

Common Reasons to Replace

Brine tanks take a beating over the years. Salt bridges, mushing, and mineral buildup can crack an old cabinet, foul the float, or leave you fighting a tank that no longer seals. If your softener is regenerating but water is not getting soft, or if you find water pooling around the base, a fresh tank with a working float assembly often solves the problem in one move. It is also a clean way to modernize a system whose valve and mineral tank are still in good shape.

Fitment and Help

Because the brine line and float connect to your specific control valve, we are happy to confirm compatibility before you buy. The assembly arrives ready to set up with the safety float and grid components it is built around, and we include the guidance we have on hand. Reach out to Water Softener Plus and we will make sure the tank, float, and your valve all speak the same language.
