Also known as backwater valves, these valves prevent backflow of sewage and wastewater in drain, waste, and vent systems.

To achieve the maximum possible flow, internal components are designed to reduce flow resistance.

Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint.

Solder these valves to copper tubing for a permanent, leak-tight connection.

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.

Barbs grip onto tubing, providing a secure hold.
