It is the genuine Pentair part, the lower half of the filter body rather than a repair for a cracked one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it fits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair carries it in the parts list for the American Products Predator cartridge filter and for the EasyClean aboveground pool DE filter system. Tank halves are sized to the square footage of the filter, so a 100 square foot bottom will not mate to a body of another size. Read the label on your filter before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tank bottom holds full system pressure. Over years of sun, freeze cycles and chemical exposure the plastic crazes and eventually splits, and once the body itself has cracked there is no reliable repair. A cracked filter under pressure is not something to keep running.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the simple things first\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA tank that weeps at the seam is more often a tired tank o-ring or a clamp band that has lost its grip. Rule those out before committing to a new bottom.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628895678676,"sku":"PAC-051-1307","price":329.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3b22e53f-2650-46b0-bd57-a2e1af4e9bc1.gif?v=1788757068","url":"https:\/\/www.activepoolsupply.com\/products\/bottom-for-100-sqft-filters","provider":"Active Pool Supply","version":"1.0","type":"link"}
