Keep your filter grids aligned with the Pentair V38-142 Bottom Spreader. Designed for FNS Plus DE filters to ensure even water flow and prevent grid shifting.

Grid Alignment: Keeps the bottom of the D.E. grids firmly in place, ensuring they remain parallel for maximum filtration surface area.
Heavy-Duty Construction: Molded from high-impact, chemical-resistant thermoplastic designed to withstand the high-pressure environment inside the filter tank.
Enhanced Flow Dynamics: Maintains the proper distance between grids to prevent "clog points," allowing for more efficient backwashing and longer filter cycles.
Direct OEM Replacement: Genuine Pentair part (V38-142) guaranteed to fit all FNS Plus series models (FNS 24, 36, 48, and 60).
Prevents Grid Damage: By stabilizing the bottom of the grids, it reduces vibration and friction that can lead to tears in the grid fabric.
