Abstract
A grid (250, 280) is disclosed which can be used as part of a salt platform (10, 50, 80) to support salt in an ion exchange water softener. The grid is preferably formed of ABS plastic and has a border portion (252) and bands (254, 256) without holes (274) formed therethrough for strength. When the grid is used as part of a salt platform having vertically oriented members (12-24) with open upper ends, cap portions (258-270), without holes formed therethrough, are used to cover the upper ends of the members.
