This is the complete internal stack for a 24 sq ft Hayward filter — eight grids, the collector manifold with its air relief, the bottom locator and the retainer rod, all built up and ready to drop into the tank. Hayward part number DEX2400DC, also sold as DEX2420DC.\u003c\/p\u003e\n\n\u003ch3\u003eReplace the cluster if\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDE is coming back into the pool:\u003c\/strong\u003e A grey cloud at the returns after recharging means the fabric has torn or the manifold has split.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure stays high after backwashing:\u003c\/strong\u003e Grids blinded with oil and scale, or a cracked collector, both hold pressure up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe filter needs cleaning constantly:\u003c\/strong\u003e Short cycles between backwashes point to reduced effective area.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA grid has collapsed or the rod is bent:\u003c\/strong\u003e One failed grid throws the whole stack out of alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt has been five years or more:\u003c\/strong\u003e Grids are a wear part, not a permanent fitting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat arrives\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e(8)\u003c\/strong\u003e 12\" DE grids, seven full and one partial — Unicel FS-2002\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e(1)\u003c\/strong\u003e Top collector manifold, DEX2400C, with flex air relief DEX2400CR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e(1)\u003c\/strong\u003e Element locator, DEX2400H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e(1)\u003c\/strong\u003e Retainer rod DEX2400R, nut ECX176865 and two ECX1109 washers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Genuine Hayward top and bottom manifolds with Unicel grid elements.

Shut off and drain the tank, pull the clamp band and lift the head, lift the old stack out, drop this one in, reseal and recharge with DE. The assembly arriving in one piece is what saves the time.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need any special tools?\u003c\/h4\u003e\n\u003cp\u003eA socket set for the clamp band and some silicone lubricant for the tank o-ring. Nothing beyond that. Lubricate the o-ring before you reseal — a dry one is the usual cause of a leak after a teardown.\u003c\/p\u003e\n\n\u003ch4\u003eWhy replace all eight grids rather than the torn one?\u003c\/h4\u003e\n\u003cp\u003eThey wear at the same rate. A grid that tears after several seasons is telling you about the condition of the other seven, and swapping one at a time means going back into the tank repeatedly.\u003c\/p\u003e\n\n\u003ch4\u003eMy filter has DE2400 on the label but this says DEX2400DC. Is that right?\u003c\/h4\u003e\n\u003cp\u003eYes. DE2400 is the filter model, DEX2400DC is the part number for the grid assembly that goes inside it. You may also see it listed as DEX2420DC, which is the same assembly.\u003c\/p\u003e\n\n\u003ch4\u003eHow much DE powder will I need?\u003c\/h4\u003e\n\u003cp\u003eRoughly 6 lbs for a 24 sq ft filter after a full teardown. Check the plate on your tank for the exact figure and add it slowly through the skimmer with the pump running.\u003c\/p\u003e\n\n\u003ch4\u003eHow often should I be tearing the filter down?\u003c\/h4\u003e\n\u003cp\u003eOnce a season for most pools, plus backwashing whenever pressure climbs 8 to 10 psi above its clean reading. Running a loaded filter is what shortens grid life more than anything else.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":67533802537260,"sku":"DEX2400DC","price":279.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/1943\/3260\/files\/Hayward_ProGrid_Filter_Complete_Element_Cluster_36_Sq._ft_Grid_Set_DEX3600DC_SOSPool_1.jpg?v=1786209300","url":"https:\/\/www.sospool.com\/products\/24-sq-ft-de-grid-assembly-hayward-progrid-de2420-dex2400dc","provider":"SOS Pool \u0026 Spa Supplies","version":"1.0","type":"link"}
