Hayward SX242MA Sand Filter Replacement Lateral Assembly - For S210SX

What This Part Is Used For
The Hayward SX242MA is a replacement lateral assembly used inside the Hayward S210SX sand filter as listed. It serves as the underdrain structure that keeps sand in place while allowing filtered water to flow back to the pool. This assembly sits at the bottom of the filter tank.

Why This Part Matters
When laterals crack, sand can blow into the pool and filtration performance drops fast. A failing underdrain also makes backwashing less effective and can keep the water cloudy even with good chemistry. Replacing the lateral assembly restores proper media retention and consistent filtration flow. This is commonly done during sand changes or after freeze related damage.
