1/2″ FNPT Dual Check Backflow Prevente (ASSE 1024 Compliant)

Description

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 FlowShieldâ„?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.
