ADDITIONAL DE FILTER GRID INFORMATION
There are two basic designs of curved vertical DE Filter Grids. The slotted collar type used by PacFab, American Products, Hayward and Sta-Rite, and the notched collar style used in Purex and Swim-Rite / Premier Atlas Filters.

The good news is all four slotted grids, i.e. Pac Fab, American, Hayward, and Sta-Rite, are interchangeable (assuming full size grids are replaced with full size and partial grids with partials).

The bad news is the two notched types are not interchangeable. Interchanging Purex and Swimrite/Premier Atlas grids in their respective tanks can cause D.E. to bleed directly into the pool. Purex grids are shorter in length than their Atlas cousins and, if put in an Atlas tank, can pop loose from the manifold during the backwash cycle. Once unseated, D.E. will pass directly into the pool when the valve is returned to the filter mode.
