It is designed for installation in sprinkler systems and other water supply applications where the risk of backflow needs to be mitigated. The device operates by maintaining a check valve that closes when water flow stops, and an air opening valve that opens when internal pressure exceeds external pressure, thereby preventing non-potable water from moving back into the clean water supply.\u003c\/p\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":45219353460958,"sku":"LSI58YTSEL","price":10649.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/libertysupply.com\/products\/lsi58ytsel","provider":"Liberty Supply","version":"1.0","type":"link"}
