3" x 1-1/2" PVC DWV Reducer

The Mueller Industries 1WKJ2 is a Schedule 40 PVC drain fitting that connects a 3-inch hub to a 1-1/2-inch hub in non-pressure drainage systems. It is intended for plumbers and DIY installers working on residential or light-commercial waste and vent piping.

Replaces solvent-weld reducers in existing DWV

Use this fitting when transitioning between the stated pipe diameters in a gravity-flow system. The jump is worth it when the installation requires a code-compliant Schedule 40 PVC reducer that meets ASTM D1784 cell class 12454 and the operating temperature does not exceed 140 degrees F.

Verify your system uses hub connections

Confirm the existing piping is Schedule 40 PVC with hub ends sized for 3-inch and 1-1/2-inch diameters. Ensure the application is strictly drain, waste and vent with no pressure requirements and that local codes accept ASTM D1784 fittings.
