It is part of the internal plumbing that routes water within the filter tank near the bottom distribution area. This component lives inside the filter and is accessed during internal service or sand changes.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e If a bottom elbow cracks or comes loose, the filter can bypass proper flow through the sand bed and water clarity can suffer. Internal plumbing failures can also make backwashing ineffective and lead to recurring debris issues. Replacing the correct S311SX elbow restores proper internal routing and helps the filter perform normally. This is often found during sand replacement when internals are exposed.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManufacturer part number: SX311CD2FW\u003c\/li\u003e \u003cli\u003eSand filter bottom elbow assembly\u003c\/li\u003e \u003cli\u003eSpecified for Hayward S311SX sand filter\u003c\/li\u003e \u003cli\u003eInstalls inside the filter tank near the bottom internal plumbing\u003c\/li\u003e \u003cli\u003eService replacement part used during sand filter rebuilds\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Open the filter only after the system is shut down and fully depressurized.
