Pentair DE Grid Replacement Filter is a replacement DE grid intended for restoring filtration performance in compatible diatomaceous earth filter assemblies. A worn, torn, or collapsed grid can reduce water clarity, allow debris to bypass the filter, or create pressure problems that make the system harder to maintain. This replacement grid gives service technicians and pool owners a direct way to refresh the internal filter pack while keeping the existing tank and manifold arrangement in service. Because DE grids are highly fit-specific, the part number 59003000 should be checked against the current grid, filter model, and manufacturer parts breakdown before installation.

Use this component when rebuilding a DE filter, correcting a damaged grid, or replacing individual elements during seasonal service. Inspect the manifold, air relief, standpipe, and remaining grids at the same time so the new part is not installed into a compromised assembly. After installation, recharge the filter with the proper amount of DE and monitor the pressure gauge during the first operating cycle.

  • Helps restore internal filtration when an existing grid is damaged or worn
  • Useful during DE filter rebuilds, cleanouts, and seasonal service
  • Verify part number 59003000 and filter model before ordering
