As compiled from documented Foundation for Cross-Connection
Control and Hydraulic Research at the University of Southern
California lab tests.
*Typical maximum system flow rate (7.5 feet/sec.)
Note: A strainer is recommended to be installed ahead of the backflow preventer to prevent the fouling of the check
assembly and resulting spillage from the valve during repressurization. Do not install in concealed locations or areas where
water leakage due to normal wear of the internal parts can cause damage.
