It is the genuine AquaStar part, supplied complete rather than as a bare stem.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the relief valve matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEvery time the pump is shut down, opened up or loses prime, air collects in the top of the filter tank. The relief valve is how that air gets out. Left in, the air pocket reduces the working area of the filter, makes the pressure gauge read oddly and puts the tank under stored pressure that has nowhere to go until someone loosens the lid clamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRelief valves live outdoors, get turned by hand every service visit and take the full sun. They crack, seize or start weeping around the stem long before anything else on the filter wears out. If yours no longer seals when closed, or will not open without a fight, change the assembly rather than fighting it.\u003c\/p\u003e","brand":"AquaStar","offers":[{"title":"Default Title","offer_id":48633662537940,"sku":"API-051-1002","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_28348be1-c3d9-4968-82aa-d86a9a9e5aff.png?v=1788808393","url":"https:\/\/www.activepoolsupply.com\/products\/aquastar-air-relief-valve-assembly-for-pipeline-filter-pf1025","provider":"Active Pool Supply","version":"1.0","type":"link"}
