Description
This 8 inch 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 gallons per minute meter to detect ground leaks and unauthorized illegal taps, greatly reducing annual water expenses. It has outside stem and yoke shutoffs. It consists of a fused epoxy coated cast iron body using ArmorTek™ coating technology for advanced corrosion resistance construction. Its modular check design facilitate simple and easy installation and maintenance. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. Maximum working pressure is 175 psi (12.06 bar).
