What is a brine tank?

A brine tank is a container used to hold a saltwater solution, typically in water softening systems. It allows the regeneration of resin beads in the softener by providing the necessary sodium ions to replace calcium and magnesium ions in hard water. The brine is created by dissolving salt in water, and the tank is designed to ensure proper mixing and concentration of the solution. Regular maintenance and refilling with salt are essential for optimal performance.
