Backflow preventers of this type protect potable water supplies by stopping reverse flow of contaminated water back into the distribution system. The atmospheric vent design provides a physical air gap that relieves pressure differentials and allows the unit to vent to atmosphere when back pressure or back siphonage conditions occur. Licensed plumbers and pipe fitters install this device as part of cross-connection control programs in residential and light commercial plumbing systems.\u003c\/p\u003e\u003cp\u003eThis atmospheric vent backflow preventer is suited for residential and light commercial plumbing installations where cross-connection control is required. The 1\/2 inch IPS connection size makes it appropriate for branch line applications, fixture supply lines, and other low-demand service points. It is commonly installed on boiler feed lines, irrigation supply connections, and similar applications where a non-pressure-type backflow prevention device meets the local code requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAtmospheric vent design provides passive air gap protection against back siphonage and back pressure\u003c\/li\u003e\n\u003cli\u003e1\/2 inch IPS connections for standard threaded pipe installation\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for tight installation spaces on branch lines\u003c\/li\u003e\n\u003cli\u003eFunctions as a cross-connection control device per applicable plumbing codes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation backflow preventer for 1\/2 inch IPS threaded plumbing systems requiring atmospheric vent-type cross-connection control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local amendments. Shut off the water supply and relieve system pressure before removing any existing device or making new connections. The atmospheric vent port must remain unobstructed and oriented correctly per the manufacturer installation instructions to function as designed. Verify that an atmospheric vent-type device meets the hazard classification requirements of the local authority having jurisdiction before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch IPS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Atmospheric\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0061935\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":67581701816626,"sku":"0061935","price":138.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/WATTS_0061935_HR.jpg?v=1790405017","url":"https:\/\/voomisupply.com\/products\/watts-0061935-atmospheric-vent-backflow-preventer","provider":"Voomi Supply","version":"1.0","type":"link"}
