Description

The FEBCO 10 inch MasterSeries LF876W/WZ is a lead-free double check detector backflow preventer assembly designed for non-health hazard (pollutant) applications. Featuring a ductile iron body with ArmorTek coating for superior corrosion resistance, this valve prevents polluted water from entering potable water systems due to backsiphonage or backpressure. It is configured for Z-pattern installations, offering a drop-in replacement for competitor valves without shutoff valves. The integrated bypass with a Gallons per Minute meter detects system leakage and unauthorized water use, making it ideal for fire protection and potable water systems. It operates up to 175 psi and between 33°F to 140°F.

FAQs

What is the primary purpose of this backflow preventer assembly?

This backflow preventer is designed to prevent the reverse flow of polluted water from entering a potable water supply due to backsiphonage or backpressure, specifically for non-health hazard (pollutant) applications in potable drinking water and fire sprinkler systems.

Does this assembly include shutoff valves?

No, this specific FEBCO MasterSeries LF876W/WZ model (SKU 88007347) is supplied without shutoff valves, as indicated by the "LG" in its model designation.

What makes this backflow preventer resistant to corrosion?

The main valve body is constructed from durable ductile iron Grade 65-45-12 and features ArmorTek powder coating, a patented three-part advanced epoxy system applied to both internal and external surfaces to resist microbial-induced corrosion (MIC) and protect exposed metal.

Can this assembly be used as a replacement for existing valves?

Yes, this assembly features a longer lay-length specifically designed for drop-in replacement of competitor’s Z-pattern backflow preventer valves, simplifying installation. It can be installed in horizontal Z-pattern or vertical-up Z-pattern orientations.

How does the auxiliary bypass system function?

The compact auxiliary bypass line includes a 5/8"x3/4" water meter that is compliant with ANSI/AWWA Standard C700. It is designed to detect potential underground water leaks and unauthorized water usage within the system.
