That makes it a single point where the whole stack can fail. A crack in the manifold, or a grid seat that has opened up, gives DE powder a route straight past the media and back to the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe classic symptom is powder returning to the pool after a recharge while the grids themselves look sound. Owners often replace grids first and see no change, because the leak is upstream of them in the manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the stack is out\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe manifold only comes free with the grid assembly, so the grids are already on the bench. Look them over for tears and thin spots in the same visit rather than opening the tank twice.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633710969044,"sku":"PAC-051-2931","price":144.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_67f428d3-5c8d-40a3-94e2-d272d78d5039.png?v=1788812311","url":"https:\/\/www.activepoolsupply.com\/products\/oem-grid-manifold-with-air-screen","provider":"Active Pool Supply","version":"1.0","type":"link"}
