This small but critical component allows trapped air to be purged from the filter tank, maintaining proper water flow and system pressure. The air relief plug seats against a filter housing port and is sealed with an O-ring to prevent leaks during operation. It is a direct OEM-style replacement part installed by pool service technicians and equipment repair professionals during routine filter maintenance or component replacement.\u003c\/p\u003e\u003cp\u003eThis air relief plug is commonly found on pool sand filters and cartridge filter housings where manual air bleeding is required. It is typically located at the top of the filter tank or on the filter head assembly. Pool service professionals replace this part when the existing plug cracks, strips, or develops a leak around the O-ring seat, causing pressure loss or water seepage at the filter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eO-ring seal design prevents leaks at the filter housing air relief port\u003c\/li\u003e\n\u003cli\u003eAllows manual bleeding of trapped air from the filter tank\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement for Waterway Plastics filter assemblies\u003c\/li\u003e\n\u003cli\u003eCompact plug format for straightforward removal and reinstallation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement air relief plug for Waterway Plastics pool filter assemblies.

Before replacing the air relief plug, shut off the pump and relieve all pressure from the filter tank by rotating the existing plug or using the multiport valve relief position. Hand-tighten the new plug and confirm the O-ring is properly seated to avoid leaks. Do not over-torque, as filter housing threads and plug bodies may be plastic.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: O-Ring Air Relief Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Pool Filtration System\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATERWAY PLASTICS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 805-0117sd-b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATERWAY PLASTICS","offers":[{"title":"Default Title","offer_id":51138452947250,"sku":"805-0117SD-B","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531894.jpg?v=1778256836","url":"https:\/\/voomisupply.com\/products\/waterway-plastics-805-0117sd-b-o-ring-air-relief-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
