Description

This 10 inch FEBCO MasterSeries LF876W Double Check Detector Backflow Preventer Assembly is designed for horizontal (N-Pattern) installation in potable water and fire sprinkler systems. It prevents backpressure and backsiphonage of polluted water into the main supply. Featuring a ductile iron body with ArmorTek® coating for enhanced corrosion resistance, this lead-free assembly provides a drop-in replacement for competitor N-pattern valves. It includes an in-line serviceable main valve with two independent check modules and a 5/8"x3/4" GPM metered bypass for leak detection and unauthorized usage. Rated for a maximum working pressure of 175 PSI, this unit is supplied without shutoff valves.
