The Guardian vent is made from corrosion-resistant, UV-protected reinforced composite with no metal parts to rust and no spare parts needed. Its large capacity releases more air than similar-size vents and dampens water hammer, protecting pipes and fittings from cracking or bursting.\u003c\/p\u003e\n\u003cp\u003eAs water enters, the float rises and closes the vent. When the line drains or pressure drops, the float falls and opens the vent to let air in, breaking the vacuum so pipelines don't collapse and soil isn't sucked into dripperlines.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAir and vacuum relief\u003c\/li\u003e\n\u003cli\u003eDampens water hammer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo metal parts\u003c\/strong\u003e – UV-protected composite.\u003c\/li\u003e\n\u003cli\u003eLarge air capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchrader valve\u003c\/strong\u003e – measure line pressure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInstall at high points and line ends, sized for your system.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNetafim\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGuardian\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3\/4\" MPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePressure rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e150 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eReinforced UV-protected composite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExtra\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSchrader valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does it protect against?\u003c\/strong\u003e\u003cbr\u003eVacuum collapse of pipes, soil being sucked into dripperlines, and water hammer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it rust?\u003c\/strong\u003e\u003cbr\u003eNo. It has no metal parts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Schrader valve for?\u003c\/strong\u003e\u003cbr\u003eMeasuring local line pressure.\u003c\/p\u003e","brand":"Netafim","offers":[{"title":"Default Title","offer_id":46403773661418,"sku":"70561-000860","price":56.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2561\/3802\/files\/image_1920_71181b03-eb56-4785-bf06-1e70ad87e385.jpg?v=1792767075","url":"https:\/\/groindoor.com\/products\/netafim-guardian-air-and-vacuum-relief-vent-w-shrader-valve-3-4in-mpt-150psi","provider":"Gro Indoor","version":"1.0","type":"link"}
