{"product_id":"lsibsz39zk","title":"Watts 0792017, 3\/4\" LF800M4-FR Backflow Preventer","description":"\u003cp\u003eThis Watts pressure vacuum breaker is designed to prevent backflow in water systems by allowing air to enter the system for pressure equalization and releasing water through a valve. It operates by maintaining a check valve to block contaminated water from reversing into clean water and an air inlet valve that opens when internal pressure drops below atmospheric pressure, thus preventing potential back siphonage. This device is typically installed in irrigation systems and other applications requiring backflow prevention to protect potable water supplies from contamination.\u003c\/p\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":45219590373598,"sku":"LSIBSZ39ZK","price":862.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/libertysupply.com\/products\/lsibsz39zk","provider":"Liberty Supply","version":"1.0","type":"link"}
