All water softener installations by Patterson’s Water & Plumbing include 200-300# of solar salt. The homeowner should always keep salt in the brine tank. There are several types of salt on the market; crystal salt, pellet salt, and potassium chloride salt (for people on salt-free diets). Pellet salt is a cleaner grade of salt, however, it does tend to bind together in the brine tank and form a salt bridge and it can also form a “brine mush” on the bottom of the salt tank. If you decide to change salt types, empty your brine tank first. This can either be done manually or by running the system through extra regeneration cycles.
