Release air until water flows steadily from the valve, then close it. Inspect the relief valve O-ring or seat for wear whenever the filter tank is open — a compromised seal here is a common source of slow leaks at the top of the filter body.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774170300691,"sku":"SX200G","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPSX200G_0.jpg?v=1747702085","url":"https:\/\/poolaroo.com\/products\/hayward-sand-filter-manual-air-relief-sx200g","provider":"Poolaroo","version":"1.0","type":"link"}
