Additional Details

The 6 inch FEBCO MasterSeries LF876V Double Check Detector Backflow Preventer Assembly is designed to prevent the reverse flow of polluted water into the potable supply due to backsiphonage or backpressure. It is primarily used on potable drinking water systems and fire sprinkler systems to detect system leakage or unauthorized water use.

This assembly can be installed in either an N-pattern (horizontal) or Z-pattern (vertical-up) configuration to optimize installation footprint and reduce costs. It incorporates a patented ArmorTek® coating for enhanced corrosion protection and is constructed with lead-free materials for safe drinking water applications.

Key Features

  • Ductile iron body construction, coated with ArmorTek® advanced epoxy system to resist microbial-induced corrosion (MIC) and protect metal substrate.
  • Lead-free design ensures the wetted surface contains less than 0.25% lead.
  • Configurable for both horizontal (N-pattern) and vertical-up (Z-pattern) installations.
  • Features two in-line independent check valves with replaceable seats and discs.
  • Includes OSY resilient seated gate valves and four properly located resilient seated test cocks.
  • Detector bypass assembly with a Gallons Per Minute (GPM) water meter (5/8"x3/4") to detect leaks or unauthorized water usage.
  • In-line serviceable design for both main valve and bypass assembly; no special tools required for servicing.
  • Captured modular spring assembly, reversible and replaceable discs, and field replaceable seats.
  • Winterization feature with disc retainers and valve body drain ports.

FAQs

What is the primary purpose of the FEBCO LF876V assembly?

The primary purpose is to protect potable drinking water and fire sprinkler systems from pollution caused by backpressure or backsiphonage, specifically for non-health hazard applications.

Can this backflow preventer be installed in different orientations?

Yes, the FEBCO LF876V assembly is designed for configurable installation in both horizontal (N-pattern) and vertical-up (Z-pattern) orientations.

What kind of corrosion protection does this assembly feature?

The ductile iron body is coated with ArmorTek®, a patented three-part advanced epoxy system engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces.

How does the detector bypass assembly function?

The detector bypass assembly includes a 5/8"x3/4" Gallons Per Minute (GPM) water meter which is designed to detect potential underground water leaks or unauthorized water usage within the system.

Is the FEBCO LF876V considered a lead-free product?

Yes, the wetted surface of this product that contacts consumable water contains less than 0.25% of lead by weight, meeting lead-free requirements.
