Product details

The Pentair 59009800 is the large DE filter grid assembly, rated at 88 GPM. It is the genuine Pentair part, supplied as a complete grid.

What the grid does

A DE filter works by holding a coat of diatomaceous earth on the fabric of its grids. The powder does the filtering, the grid holds it in place. When the fabric tears or pulls away from the frame, the DE goes straight through and comes back into the pool through the returns.

Ordering

This is the large grid. Pentair grid sets pair full size grids with a shorter partial, so check which one you are missing before ordering. Since the whole set ages at the same rate, it is worth inspecting the rest while the filter is apart.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this the large grid or the partial?
The large one. A DE grid set usually mixes full size grids with one shorter partial grid, and this is the large full height assembly.
How do I know a grid has failed?
DE powder blowing back into the pool through the returns after you charge the filter is the classic sign. Open the filter and look for a tear, a split seam or fabric pulled away from the frame.
Should I replace one grid or the whole set?
If the rest of the set is the same age and looks worn or thin, replacing them together saves opening the filter twice. A single fresh grid among old ones is fine as a stopgap.
Is it a genuine Pentair part?
Yes. It is the Pentair OEM grid assembly, part 59009800.
