Additional Details

The 8 inch FEBCO MasterSeries LF876V Double Check Detector Backflow Preventer Assembly with OSY shutoff valves and a GPM meter is designed to protect potable water supplies from pollution due to backpressure or backsiphonage. This lead-free assembly is primarily used on potable drinking water systems and fire sprinkler systems where local codes require protection against non-potable water flowing back into the system.

The unit features a configurable design allowing for both N-pattern (horizontal) and Z-pattern (vertical-up) installations, which helps reduce installation footprint and costs. It includes a bypass line with a gallons per minute (GPM) meter to detect potential system leakage or unauthorized water usage.

Construction & Coating

  • Main valve body made from ductile iron Grade 65-45-12.
  • All iron components, including internal and external surfaces, are coated with ArmorTek®, a patented three-part advanced epoxy system.
  • This coating is engineered to resist microbial-induced corrosion (MIC) and protect exposed metal substrate.
  • Wetted surfaces contain less than 0.25% lead by weight, meeting lead-free requirements.

Main Valve Features

  • In-line serviceable design.
  • Horizontal N-pattern and Vertical-Up Z-pattern installation capabilities.
  • Servicing requires no special tools, with access through independent top entry covers.

FAQs

What is the primary purpose of the FEBCO MasterSeries LF876V 8 inch backflow preventer?

Its primary purpose is to protect potable drinking water systems and fire sprinkler systems from contamination caused by backpressure or backsiphonage of non-potable water, as required by local codes.

What does the ArmorTek® coating on this backflow preventer do?

The ArmorTek® coating is a patented three-part advanced epoxy system applied to all iron components. It is designed to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces, extending the product's lifespan.

Can this 8 inch backflow preventer be installed in different orientations?

Yes, the configurable design allows for both horizontal (N-Pattern) and vertical-up (Z-Pattern) installations. This flexibility can help optimize the installation footprint and reduce costs.

What is the function of the GPM meter in the auxiliary bypass line?

The Gallons Per Minute (GPM) meter in the auxiliary bypass line is designed to detect potential underground water leaks or unauthorized water usage within the system, providing an important monitoring capability.

Is this 8 inch backflow preventer suitable for use with potable water?

Yes, this assembly is lead-free, meaning the wetted surfaces contain less than 0.25% lead by weight, making it safe and compliant for use with potable drinking water systems.
