Hayward SX202QA Sand Filter Replacement Lateral Assembly - For S200T

What This Part Is Used For
The Hayward SX202QA is a replacement lateral assembly used inside the Hayward S200T sand filter as listed. Laterals form the underdrain at the bottom of the filter 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 repairs.

Why This Part Matters
When laterals crack, sand can return to the pool and show up as gritty debris at the returns. A compromised underdrain also reduces filtration efficiency and makes backwashing less effective. Replacing the correct lateral assembly restores proper media retention and consistent water clarity. This is often done when the filter is opened for a sand replacement.
