709DCDA-OSY 10 3/4GPM

This 10 IN double check detector backflow preventer assembly prevents backflow of non-health hazard fire protection system substances from being pumped or siphoned into the potable water supply. It incorporates a 3/4 IN bypass with a gallons per minute meter to detect ground leaks and unauthorized illegal taps, and to aid in reducing annual water expenses. It consists of a fused epoxy coated cast iron body using ArmorTek(TM) coating technology for advanced corrosion resistance construction. Its modular check is designed for simple and easy installation and maintenance. It has outside stem and yoke shutoffs. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. The maximum working pressure is 175 psi (12.06 bar).
