Anti-siphon valves combine a zone control valve and a backflow preventer into a single unit, stopping contaminated water from being drawn back into the potable supply line when pressure drops. At 0.75 inches, this valve suits standard lateral lines found in typical sprinkler and drip irrigation layouts. Installation is handled by licensed irrigation contractors or plumbers working on outdoor water systems.\u003c\/p\u003e\u003cp\u003eThis valve is suited for above-ground installation on residential lawn and garden irrigation systems where local code requires backflow protection at the zone level. The anti-siphon design must be installed at least 6 inches above the highest downstream sprinkler head to function correctly per standard irrigation practice. It is a practical choice for new irrigation zone installations as well as direct replacement of failed or leaking anti-siphon valves on existing systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.75-inch valve size fits standard 3\/4-inch irrigation lateral lines\u003c\/li\u003e\n\u003cli\u003eIntegrated anti-siphon design combines zone shutoff and backflow prevention in one unit\u003c\/li\u003e\n\u003cli\u003ePlastic body construction offers corrosion resistance for outdoor irrigation use\u003c\/li\u003e\n\u003cli\u003eCompact form factor simplifies installation in valve boxes or at manifold assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for 3\/4-inch anti-siphon valve applications in residential and light commercial irrigation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or certified irrigation technician in accordance with local plumbing and irrigation codes. Shut off the irrigation water supply fully before removing or installing the valve. The valve must be mounted above the highest downstream emission point to maintain proper anti-siphon function. Do not install this valve in a below-grade or flooded valve box where the body could be submerged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Anti-Siphon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TORO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 311A-.75\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TORO","offers":[{"title":"Default Title","offer_id":51396301881650,"sku":"311A-.75","price":58.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312833545.jpg?v=1782829571","url":"https:\/\/voomisupply.com\/products\/toro-311a-75-plastic-anti-siphon-valve-0-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
