The Jones Stephens B01-004 backwater valve is designed to be compatible with
4-inch No-Hub cast iron piping systems. It utilizes No-Hub connections on both ends, secured by neoprene gaskets and stainless-steel bolts and washers.
While specifically designed for cast iron No-Hub connections, it's possible to connect this valve to other piping materials like PVC, ABS, ductile iron, and service brass using appropriate transition couplings or adapters. These specialized couplings create a secure and watertight connection between different pipe types, and the No-Hub ends of the valve.
Features: Transition Couplings:To connect to other pipe materials, ensure the correct transition couplings are used that are specifically designed for connecting cast iron to the desired pipe material.
Installation:The valve is designed forhorizontal installationand must be installed with the access opening facing upwards.
Direction of Flow: The arrows on the valve indicate the proper direction of flow and must be followed during installation.
Solvent Cement:Be careful not to allow solvent cement (used for some plastic pipes) to enter the valve body during installation as it can damage the flapper.
Reduces Backflow: The primary function is to prevent sewage backup and reduce the reverse flow of wastewater in drainage systems.
No-Hub Connection: Designed for use with No-Hub cast iron piping, this valve comes complete with neoprene gaskets and stainless-steel bolts and washers for secure and leak-free connections.
