It is the genuine Hayward replacement for the S311SX, 311SXV and 360SX tanks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the build date\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward lists this elbow for S-311 filters built after 1996. Tanks from before that change use different internals, so read the label on the tank before you order rather than matching on the model number alone. The source listings also show the second model as 311SXV in one place and 311XV in another, so compare against your own tank label if you are close to that model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bottom elbow sits deep inside the tank where the standpipe meets the lower plumbing. Everything the filter passes moves through that joint, so when it cracks or loosens, sand starts finding its way back to the pool through the return lines. Replacing the elbow while the tank is open is far quicker than opening it twice.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48633932054740,"sku":"HAY-051-1451","price":106.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1436220b-a119-41af-a4d6-5981c1c135d9.png?v=1788817533","url":"https:\/\/www.activepoolsupply.com\/products\/bottom-elbow-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
