Hayward SX160QA Sand Filter Lateral Assembly With Center Pipe - For S160T

What This Part Is Used For
The Hayward SX160QA is a lateral assembly with center pipe used inside the Hayward S160T sand filter as listed. It forms the internal underdrain that collects filtered water while keeping sand media in the tank. This assembly sits at the bottom of the filter and is accessed during sand changes and internal repairs.

Why This Part Matters
When laterals crack or the center pipe connection fails, sand can return to the pool through the returns and water clarity drops quickly. A compromised underdrain also makes backwashing less effective and can cause channeling through the sand bed. Replacing the correct assembly restores proper media retention and consistent filtration flow. This is most often handled during a sand replacement or after freeze damage.
