About This Item

The Pleatco PFS1836 is a complete DE filter grid set engineered for 18" × 11" pool DE filter systems — delivering everything needed for a full filter re-grid service in a single purchase. Designed for broad OEM compatibility across American, Astral, Hayward, Pac-Fab, Pentair, and Waterway filter platforms, this 8-piece set pairs precision-dimensioned full grids with the required partial grid to restore your filter to peak filtration performance. Built with high-grade DE filter fabric and reinforced construction, these grids are engineered to withstand the sustained operating pressures of residential and commercial pool filtration systems.

📦 Complete DE Filter Grid Set — 8 Grids Included
This set includes everything needed for one complete filter re-grid: 7 full grids (PFG1836) + 1 partial grid (PHG1836 Pleatco Partial DE Filter Grid). One set = one complete filter service.

Note: The companion full grid (PFG1836) is also available individually — search PFG1836 if you need to replace individual full grids only.

Pro Tips

  • Safety First: Always turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank to replace grids.
  • Verify Your Configuration: Before ordering, count your existing grids and confirm your filter uses 7 full grids + 1 partial grid. Verify grid dimensions match 18" × 11" specifications before purchase.
  • One Set, One Service: This set is sized for a single complete re-grid. If you are servicing multiple filters or prefer to keep spare grids on hand, order accordingly.
  • Inspect at Service Time: Check the tank o-ring, manifold seals, and bump mechanism (if applicable) whenever performing a grid replacement — replace worn components to maintain pressure integrity.
  • Universal Fit Note: This grid set is designed to fit 18" × 11" DE filter systems across multiple OEM brands. Always confirm your existing grid dimensions before ordering to ensure compatibility.
