Inspect the manifold hub and standpipe O-rings while the tank is open — replacing worn seals at the same time prevents a second disassembly.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54308414062867,"sku":"SX242MA","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-replacement-lateral-assembly-for-pro-series-sand-filters-w3s210s-w3s310s-sx242ma-1.webp?v=1789957385","url":"https:\/\/poolaroo.com\/products\/haywardpoolproductsinc_sx242ma","provider":"Poolaroo","version":"1.0","type":"link"}
