Installation & Connections
This assembly is designed for horizontal N pattern installation and must be installed in accordance with the direction of the flow arrow.
It features groove couplings for easy installation and pipe alignment with compatible piping systems.
This Maxim™ 8 inch lead free Reduced Pressure Zone Backflow Preventer Assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and/or backpressure.
It is suitable for continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. This assembly is approved for horizontal N pattern installation as long as the backflow assembly is installed in accordance with the direction of the flow arrow.
