Hayward SX242MA3 Sand Filter Replacement Lateral Assembly - For S360SX

What This Part Is Used For
The Hayward SX242MA3 is a replacement lateral assembly used inside the Hayward S360SX sand filter as listed. Laterals form the underdrain at the bottom of the sand bed and keep sand in the tank while allowing filtered water to pass through. This assembly lives inside the filter and is accessed during sand changes and internal service.

Why This Part Matters
Cracked laterals are a common cause of sand returning to the pool through the returns. When laterals fail, filtration suffers and the pool can become cloudy and gritty. Replacing the lateral assembly restores proper underdrain function and keeps media where it belongs. This is often handled during a sand replacement when the filter is already opened.
