It is rated to 188 gpm and holds velocity at the floor to 1.396 feet per second at that maximum.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the sump requirement goes away\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA conventional main drain needs a sump field fabricated to the 1.5 times pipe diameter rule, which is slow work in a concrete shell and easy to get wrong. The SDX2 is approved as a bulkhead fitting, with the safety carried by the cover and the backplate, so no sump has to be built behind it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow it carries the flow\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe face uses a patented ribbed design that splits the opening into 60 independent flow partitions. That spreads the draw across a large area rather than concentrating it, which is what keeps floor velocity low at full flow. A center shield in the middle of the grate blocks direct contact with the suction.\u003c\/p\u003e\u003cp\u003eThis version comes with a plaster ring for new concrete applications. If you are replacing an existing suction fitting rather than building new, the SDX2 Retro is the separate part to look at.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48625849794772,"sku":"PMT-25-4120","price":57.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_161ce340-228d-4dd6-9dd4-12426cea65ea.jpg?v=1788701625","url":"https:\/\/www.activepoolsupply.com\/products\/main-drain-grate-paramount-sdx2-concrete-white","provider":"Active Pool Supply","version":"1.0","type":"link"}
