The LF909 Backflow preventer features an exclusive air-in-water-out principle relief valve for increased protection during backflow emergencies. The coating on this backflow assembly uses ArmorTek(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. The assembly uses OSY shutoffs. This backflow assembly also includes a backflow flood sensor alert that monitors the condition of your backflow assembly 24\/7 and alerts you in the event of RPZ discharge. Simply connect to the SentryPlus Alert System or to your BMS and activate it.","brand":"Water Specialties Company","offers":[{"title":"Default Title","offer_id":50164300972309,"sku":"DDP0113182","price":54604.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0874\/6506\/6773\/files\/193535.jpg?v=1789571031"}],"url":"https:\/\/www.backflowpreventer.com\/collections\/backflow-devices-watts-rpz-reduced-pressure-zone-assemblies-8-909-series.oembed","provider":"Water Specialties Company","version":"1.0","type":"link"}
