Wh y Wo rk w i t h F E B C O?Safeguarding the drinking water supply is critical to protecting human health. For 50 years FEBCO has designed and manufacturedinnovative and patented assemblies for this critical purpose. FEBCO’s backflow prevention assemblies, which prevent the backwardflow of contaminated water into the potable water supply, are reliable and easily serviced. What’s more, they offer one of the lowesttotal installed costs in the industry.From FEBCO’s earliest days, experienced engineers have combined expert knowledge, technological advances, industry innovation,and broad manufacturing experience to design and manufacture one of the widest lines of top-quality backflow prevention assemblies available.FEBCO works closely with municipalities, engineers, architects, and contractors to solve their unique backflow prevention issues, andprovides educational materials to the general public for building awareness around the importance of safeguarding potable water.Why work with FEBCO? Simple. Superior designs, innovative technology, state-of-the-art manufacturing facilities, and acommitment to keeping all drinking water clean and safe with reliable and trusted backflow prevention assemblies.Lead Free TransitionWith the changeover to lead free in the United States that became effective January 4, 2014, lead free backflow preventiondevices are required in certain applications and/or settings. The FEBCO backflow preventer line includes top-quality, fully-tested LeadFree* versions of our standard backflow products.Standard Material Products (not Lead Free*) CONTAIN MORE THAN 0.25% LEAD.Effective January 4, 2014, it is illegal to use this product in any plumbing system providing water for human consumption,such as drinking or dishwashing, in the United States.Before installing standard material product, consult your local water authority, building and plumbing codes.Industry TermsBackpressure: Pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or other means that cancause backflow.Backsiphonage: Backflow caused by negative or reduced pressure in the supply piping.Cross-connection: A connection or potential connection between any part of the potable water system and another environmentwhere undesirable substances could enter the potable water system. Contaminated or undesirable substances can include gases,liquids, or solids, such as chemicals, waste products, steam, water from other sources (potable or non-potable), or any other matter that can change the color of or add odor to the water. Bypass arrangements, jumper connections, removable sections, swivel orchangeover assemblies, or any other temporary or permanent connecting arrangement where backflow can occur are consideredcross-connections.* The wetted surface of this product contacted by consumable watercontains less than 0.25% of lead by weight.
Degrees of Health HazardHealth hazard: A cross-connection or potential cross-connection where any substance that could cause death, illness,or spread disease, or have a high probability of causing such effects, could be introduced into the potable water supply.Non-health hazard: A cross-connection or potential cross-connection where any substance introduced into the potable watersupply would generally not be considered a health hazard, but would constitute a nuisance or be aesthetically AZARD Reduced PressureDetector Assemblies LF870VLF850850/850ULF850/LF850UDouble Check ValveAssemblies 876VST856STDouble CheckDetector Assemblies 765/765ULF767FRPressure VacuumBreaker Assemblies 710/715Atmospheric Vacuum Breaker LF880VLF860860/860U/ LF860/LF860UReduced Pressure Zone825/LF825Assemblies825YA/LF825YA826YD!
