Fisher Manufacturing 2932-0002 Backflow Preventer Leadfree SS 3/4

The Fisher Manufacturing 2932-0002 Backflow Preventer allows water to flow in one direction while stopping reverse movement, that could return into the supply line. Its internal check mechanism responds to changes in water pressure, closing the flow path when backflow conditions occur. It is installed on compatible commercial plumbing systems with 3/4-inch water lines, where it connects between the supply piping and connected equipment. Constructed from lead-free stainless steel, the pair is designed to match the specified connection size and system requirements.
