The lower body, the grids or cartridges and the internal plumbing are not included and stay with your existing filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTank tops fail from age, sun and pressure cycling. A hairline crack that weeps only when the pump runs, a split at the clamp land, or a rim that has distorted enough that the clamp no longer pulls the halves together all mean the upper body is finished. Replacing it is far less work and expense than replacing a filter whose lower half is still perfectly sound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRead the model number off the filter label. The Pro-Grid and SwimClear ranges share several parts but each tank size uses its own upper body.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48627860766932,"sku":"HAY-051-1063","price":772.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c2e5855b-7ecb-4361-9fb3-1eca6950143f.png?v=1788728527","url":"https:\/\/www.activepoolsupply.com\/products\/upper-filter-body-de4820","provider":"Active Pool Supply","version":"1.0","type":"link"}
