Reusing aged seals with a new header is a common cause of post-service leaks. Have a licensed pool professional or certified HVAC technician perform the replacement — gas heater disassembly involves both pressurised water connections and gas-side components that require proper certification to service safely.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774096310547,"sku":"FDXLFHA1930","price":325.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-fd-pool-heater-header-fdxlfha1930.webp?v=1781813173","url":"https:\/\/poolaroo.com\/products\/hayward-fd-pool-heater-header-fdxlfha1930","provider":"Poolaroo","version":"1.0","type":"link"}
