FAQs

What type of backflow protection does the FEBCO LF870V provide?

The FEBCO LF870V Double Check Valve Assembly is designed to protect against backpressure and backsiphonage conditions for non-health hazard (pollutant) applications. It prevents non-potable quality water from entering potable drinking water systems.

Is this 8 inch backflow preventer lead-free?

Yes, the FEBCO MasterSeries LF870V features Lead Free* construction. The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight, complying with low lead installation requirements.

What is ArmorTek® coating technology and what are its benefits?

ArmorTek® is a patented three-part advanced epoxy system applied to the iron components of the backflow preventer. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate, delivering integrated protection against electrochemical corrosion.

Can this backflow preventer be installed in different orientations?

Yes, the FEBCO LF870V is approved for both horizontal (N-pattern) and vertical-up (Z-pattern) installations. The assembly is shipped in the standard N-pattern configuration.

What are the primary materials used in the construction of this assembly?

The main valve body is made of Ductile Iron Grade 65-45-12 with ArmorTek® powder coating. It features stainless steel check seats, disc holders, and springs, with silicone elastomer discs and AWWA C606 clamps. Shutoff valves are NRS resilient wedge gate valves.
