{"product_id":"sx310at","title":"Hayward S310S Air Relief Tube w\/Locknut [After 07\/2024] (SX310AT)","description":"\u003cp\u003eReplace the air-relief tube and locknut on a compatible Hayward S310S filter built after July 2024. This is an internal service assembly, not the external manual air-relief valve.\u003c\/p\u003e\u003ch3 style=\"margin:16px 0 5px;padding:0;\"\u003eHow This Component Fits the System\u003c\/h3\u003e\u003cp style=\"margin-top:0;\"\u003eIn a high-rate sand filter, incoming water is distributed across the sand bed, suspended particles are trapped by the filtration media, and filtered water is collected by the internal underdrain and returned to the pool. Internal diffusers, laterals, standpipes, and air-relief plumbing each perform a different role. Hayward explains this water path in its ProSeries service literature; replacing the correct internal component matters to efficient operation and avoiding unwanted sand migration.\u003c\/p\u003e\u003cp\u003eVerify manufacturing date and model, because pre-July-2024 filter versions may require different parts.\u003c\/p\u003e\u003cp\u003eThis specific listing identifies a newer-production component. Verify the equipment build date carefully; a similarly named older assembly may have a different geometry or connection arrangement.\u003c\/p\u003e\u003ch3 style=\"margin:16px 0 5px;padding:0;\"\u003eReplacement and Maintenance Considerations\u003c\/h3\u003e\u003cp style=\"margin-top:0;\"\u003eA well-planned repair includes inspecting the condition of the neighboring assembly before reinstalling the replacement. Look for worn mating surfaces, loose retainers, damaged connections, corrosion, or other conditions relevant to the component being serviced. Recommission the system using the manufacturer procedure rather than assuming that installing a new part alone resolves the original operating problem.\u003c\/p\u003e\u003cp\u003eFor this particular listing, the ordering reference is SX310AT. The identifying description is Hayward S310S Air Relief Tube w\/Locknut [After 07\/2024] (SX310AT). Matching the original unit and the manufacturer parts illustration is particularly important where closely related models have different mounting or electrical requirements.\u003c\/p\u003e\u003ch3 style=\"margin:16px 0 5px;padding:0;\"\u003ePractical Features and Service Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaintains the intended water path through the sand-filtration assembly.\u003c\/li\u003e\n\u003cli\u003eA correctly installed internal component helps prevent bypass or unwanted disturbance of filter media.\u003c\/li\u003e\n\u003cli\u003eInspecting the sand bed while the filter is opened can reveal broken parts or misplaced media.\u003c\/li\u003e\n\u003cli\u003eProduction-date revisions should be checked against the tank label and relevant service diagram.\u003c\/li\u003e\n\u003cli\u003eDepressurize, isolate, and drain the filter before opening or servicing any pressurized component.\u003c\/li\u003e\n\u003cli\u003eConfirm the post-July 2024 design before installing this service item.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward Pool Products","offers":[{"title":"Default Title","offer_id":49882374209691,"sku":"SX310AT","price":28.41,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1751\/9347\/files\/noimage_0de9f730-c763-4c01-b418-4f62bc1fbe27.jpg?v=1792629436","url":"https:\/\/www.bathandspaparts.com\/en-ca\/products\/sx310at","provider":"Bath and Spa Parts Online","version":"1.0","type":"link"}
