What This Part Is Used For
This sand filter is used to remove particulate debris from pool water through a sand media bed. The top mount valve controls filtration, backwashing, and rinsing functions. It is designed for residential pool circulation systems. The 22 inch tank size supports higher flow rates. This filter plays a central role in water clarity.

Why This Part Matters
