Hayward SX310CD2FW Sand Filter Bottom Internal Elbow Assembly - For S310SX

What This Part Is Used For
The Hayward SX310CD2FW is a bottom internal elbow assembly used inside the Hayward S310SX sand filter as listed. It is part of the internal plumbing that directs water flow within the filter tank near the bottom distribution area. This component is accessed during internal service and sand changes.

Why This Part Matters
If internal elbows crack or loosen, the filter may not route water correctly through the sand bed. That can cause poor filtration, ineffective backwashing, and persistent cloudiness even with proper chemistry. Replacing the correct S310SX elbow restores internal flow routing and helps the filter perform normally. This is often handled while the filter is opened for a sand replacement or major leak repair.
