Pro Tip: Always turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank. When installing, verify each grid's collar notch seats correctly into the manifold — a misaligned or skipped grid causes unfiltered water bypass. Measure your existing full grid end to end (excluding collar) to confirm the 30" length matches before ordering. Grids only — does not include manifold, standpipe, or o-rings.
