Hayward SX180DA Sand Filter Lateral Assembly With Center Pipe - For S180T
What This Part Is Used For
The Hayward SX180DA is a lateral assembly with center pipe used inside the Hayward S180T sand filter as listed. It forms the internal underdrain that collects filtered water and keeps 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 damaged underdrain also reduces backwash performance and can cause channeling in the sand bed. Replacing the correct assembly restores proper media retention and consistent filtration flow. This is a common fix during a sand replacement or after freeze damage.
