Product Description
⌄The Filbur FS-3037 is a full eleven grid replacement set for the Sta-Rite System 3 S7D75 DE filter. It is grids only: the manifold, retainer and hardware from your existing element stay in service, and the new grids go on in place of the old ones.
What is in the set
Three offset port grids, one at 12-7/16 in. and two at 13-13/16 in., and eight center port grids, two each at 9-11/16, 12-7/16, 15-3/16 and 16-1/2 in. Every grid is 18 in. long. Together they replace the complete grid pack in the S7D75 tank.
Before you order
Confirm the filter is the S7D75. The larger System 3 S8D110 takes a thirteen grid set instead. While the tank is apart it is worth checking the 21 in. tank o-ring and replacing it if it has flattened or cracked.
