It features a brass body and a silicone seat. Rated to 125 psi and 33°F to 180°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 3\/4 inch satin chrome lead free anti-siphon hot or cold water vacuum breaker backflow preventer prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage. It consists of chemical resistant silicone seat disc, chrome hood, and an atmospheric vent to prevent spilling. It has a full size orifice to assure pipe size capacity and maximum flow. It is ideal for low flow, non-continuous hot or cold water health hazard installations such as on laboratory equipment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLead free construction\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish\u003c\/li\u003e\n\u003cli\u003eFemale NPT inlet and outlet\u003c\/li\u003e\n\u003cli\u003eHot or cold water\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this AVB approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for high health hazard (toxic) cross-connections, but only against backsiphonage.

It will not stop backflow caused by backpressure — a downstream pump, elevated piping or a boiler — which requires a double check or RPZ assembly. It also may not be used under continuous pressure: the supply downstream of it must not stay pressurized for more than 12 hours in any 24-hour period.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eHow does this have to be installed?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt must be installed vertically (upright), above the highest downstream outlet, per the installation instructions and its ASSE listing.\u003c\/dd\u003e\n\u003c\/dl\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e AVB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat \/ Seal Material:\u003c\/strong\u003e Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure (psi):\u003c\/strong\u003e 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Domestic Water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackflow Protection:\u003c\/strong\u003e Backsiphonage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e Non-Continuous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 Year Limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e LF288ASC-Z6 3\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e 33°F to 180°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASSE-1001, ANSI-A112.1.1, CSA-B64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Type:\u003c\/strong\u003e AVB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHazard Protection Level:\u003c\/strong\u003e High Health Hazard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASSE Standard:\u003c\/strong\u003e ASSE 1001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSC FCCCHR Approved:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Testable:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Test Cocks:\u003c\/strong\u003e 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShutoff Valves:\u003c\/strong\u003e None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproved Orientation:\u003c\/strong\u003e Vertical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlood Sensor (SentryPlus Alert):\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrainer Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Gap Fitting Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":31243980341353,"sku":"0792059","price":332.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/0cc8099f464afe0123cd85aa902f705ce4cde565_cc04b3be-ea3a-4fb0-8578-5194d18ecfdf.jpg?v=1785977240","url":"https:\/\/citysupplygroup.com\/products\/watts-lf288asc-z6-3-4-blackflow-preventer","provider":"City Supply","version":"1.0","type":"link"}
