What purpose of the Multilevel Salt Support in the bottom of the brine tank, and what do other softeners usually have?
It not only allows the use of inexpensive types of salt, but also has a patent pending design that traps dirt and debris away form the brine draw area, greatly reducing maintenance. This also prevents the salt from bridging and caking to the bottom of the tank. Your brine is being sucked from the bottom of the tank. Other softeners may not have one.
