{"product_id":"x1010574","title":"Hayward S244S\/S310S Air Relief Tube Locknut (X1010574)","description":"\u003cp\u003eThis Hayward locknut is used with the air-relief tube assembly on compatible S244S and S310S sand filters. It replaces the fastening component without requiring a complete tube assembly.\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\u003eConfirm the original tube and nut configuration. The tube itself is not included unless separately specified.\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 X1010574. The identifying description is Hayward S244S\/S310S Air Relief Tube Locknut (X1010574). 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\u003eReplacing the affected subassembly can avoid unnecessary replacement of a serviceable filter tank.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hayward Pool Products","offers":[{"title":"Default Title","offer_id":49882374144155,"sku":"X1010574","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1751\/9347\/files\/noimage_8768df1d-d777-4b17-aca7-c0280503a74c.jpg?v=1792629436","url":"https:\/\/www.bathandspaparts.com\/products\/x1010574","provider":"Bath and Spa Parts Online","version":"1.0","type":"link"}
