When this plate is cracked, warped, or worn, the pump loses hydraulic efficiency and flow rate drops — replacing it with the OEM component restores the designed flow path and pressure output.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eSPX1425B\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e610377038331\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePoolaroo Pro Tip\u003c\/h3\u003e\n\u003cp\u003eWhen replacing the top diffuser plate, inspect the full diffuser assembly — impeller, diffuser body, and shaft seal — for wear at the same service interval. Addressing all worn internal components in one service visit prevents repeat pump teardowns and ensures the restored hydraulic path performs as designed. Always confirm the part number against your pump's model label or exploded diagram before ordering, as diffuser plate designs vary across Hayward pump families.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774178689299,"sku":"SPX1425B","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPSPX1425B_0.jpg?v=1747702585","url":"https:\/\/poolaroo.com\/products\/hayward-fitting-top-diffuser-plate-spx1425b","provider":"Poolaroo","version":"1.0","type":"link"}
