It is the genuine Hayward part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir collects at the top of a filter tank every time the system is opened or loses prime. The relief tube is what gives that air a path from inside the tank to the relief valve on the lid, so it can be bled off before the pump is restarted. A tank that will not bleed properly is slow to prime and runs at poor flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplace it if it is cracked, broken or missing. Because it sits inside the tank head, the sensible time to fit a new one is while the filter is already open for a cartridge change rather than opening the tank a second time later.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48629133770964,"sku":"HAY-051-1529","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1f9f7850-4018-4f8b-8558-144bbd1b105b.jpg?v=1788759928","url":"https:\/\/www.activepoolsupply.com\/products\/air-relief-tube","provider":"Active Pool Supply","version":"1.0","type":"link"}
