Additional Details

The FEBCO MasterSeries LF876WZ Double Check Detector Assembly is a 10 inch lead-free backflow preventer specifically designed to prevent the reverse flow of polluted water into potable water supplies due to backsiphonage or backpressure. This Z-pattern assembly is primarily used on potable drinking water systems and fire sprinkler systems, providing protection against non-health hazard (pollutant) contamination. It includes a metered bypass for detecting system leakage or unauthorized water usage.

Construction & Design

  • Features an epoxy-coated ductile iron body with ArmorTek coating technology for advanced resistance against electrochemical and microbial-induced corrosion.
  • Equipped with two independently acting clapper style check modules with replaceable seats and disc rubbers, designed for in-line servicing without special tools.
  • Includes OSY resilient seated domestic gate valves for shutoff and four properly located resilient seated test cocks.
  • The auxiliary bypass line contains a 5/8"x3/4" Water Meter (GPM) to detect potential underground water leaks and unauthorized water usage.
  • Designed for horizontal and/or vertical-up installations, meeting AWWA Standard C510 flow and pressure loss parameters.

FAQs

What is the primary function of the FEBCO MasterSeries LF876WZ assembly?

Its primary function is to prevent the reverse flow of polluted water into potable drinking water and fire sprinkler systems, protecting against non-health hazard (pollutant) contamination due to backsiphonage or backpressure.

What is the maximum operating pressure and temperature for this backflow preventer?

The maximum operating pressure is 175 psi (12.1 bar), and the continuous temperature range is 33°F to 140°F (0.5°C to 60°C).

What does the ArmorTek coating provide for the valve?

The ArmorTek coating is a patented three-part advanced epoxy system applied to the ductile iron body to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces from electrochemical corrosion.

Can this assembly be installed in different orientations?

Yes, the assembly is approved for both horizontal and vertical-up installations, providing flexibility for various site requirements.

How does the auxiliary bypass line function?

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