The FEBCO 876V is primarily used in fire sprinkler systems, standpipe systems, and high-flow non-potable water lines. It prevents contaminated water from flowing back into the main supply while also monitoring hidden leakage and unauthorized consumption.
It is commonly selected by contractors and engineers who need a reliable Backflow preventer solution for large buildings, industrial facilities, and commercial infrastructure projects. Available through Deluxe Plumbing Supplies, this assembly supports projects requiring compliance and dependable long-term operation.
A Double Check Detector Assembly uses two independently operating spring-loaded check valves that stop reverse water movement. A bypass assembly with an integrated meter monitors low-flow activity that could indicate leakage or unauthorized use.
The monitoring function becomes especially important in fire protection systems where unnoticed water usage may indicate system problems. The system works according to Backflow prevention principles used in commercial plumbing safety practices.
The MasterSeries configuration allows installers to adapt the system according to available site conditions and space limitations.
