Professional Notes

The IPEX 223284W backwater valve is intended for installation by licensed plumbing professionals in gravity-flow drain, waste, and vent (DWV) systems. The PVC body offers high chemical resistance and ease of solvent-weld joining to standard Schedule 40 PVC piping. The gravity-actuated flapper closes automatically upon backflow to prevent system surcharge and contamination. This valve is suitable for use in main sanitary or storm laterals where backflow prevention is mandated by plumbing code. Regular inspection is recommended to maintain unobstructed movement of the flapper assembly.
