When the manifold cracks or the grid ports wear, DE gets past the grids and back into the pool, and the filter never quite clears the water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the manifold assembly on its own. Grids, the standpipe and the clamp hardware are separate parts, so open the tank and check the grids while the manifold is out. If they are torn or thin, replacing them at the same time saves a second teardown.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48625791008980,"sku":"CTM-051-1253","price":75.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_4f451cea-38ce-44c7-b119-caac49439c88.jpg?v=1788700168","url":"https:\/\/www.activepoolsupply.com\/products\/fns-plus-top-manifold-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
