Overview
Low lead dual check valve backflow preventer is designed for residential domestic water supply lines or commercial low-hazard backflow applications. It prevents reverse flow of unsafe water into main system water supply. This can occur due to pressure changes in the distribution network that can force water flow in reverse, or backwards. The two inline serviceable check valves prevent any contact between the two systems, closing automatically when backflow conditions occur.
The Caleffi 3048 series FlowShield™ DuC complies with standards ASSE 1024, CSA B64.6, NSF/ANSI/CAN 61 (180 °F/82 °C Commercial Hot), NSF/ANSI/CAN 372 and codes IPC, IRC, UPC certified by ICCES.
