Charlotte Pipe PVC-102-4X8 Pvc Dwv Reducer Coupling 4x8 in

Product Description

The CHARLOTTE PIPE PVC-102-4X8 is a PVC DWV increaser reducer coupling designed to transition between 4-inch and 8-inch drain, waste, and vent piping. This fitting is engineered for gravity-fed, non-pressure waste elimination systems and is rated for service up to 140 degrees F. Made from lightweight PVC, it simplifies handling and positioning during installation without sacrificing durability. Licensed plumbers and pipefitters install this fitting in residential and commercial DWV systems where a pipe diameter change is needed inline. Solvent cement joining keeps the process straightforward and eliminates the need for specialty tooling.

This reducer coupling is used wherever a DWV system requires a step-up or step-down transition between 4-inch and 8-inch PVC pipe runs. Typical applications include main drain stacks, building drain transitions, and vent stack connections in both residential and light commercial construction. The fitting is compatible with standard PVC DWV pipe and accepts solvent cementing, threading, flanging, and roll-grooved joining methods, giving installers flexibility based on site conditions and local code requirements.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the pipe run is fully drained before cutting into an existing system. When solvent cementing, use a PVC-rated primer and cement appropriate for the pipe schedule and follow the manufacturer's cure time before restoring flow. Cutting can be performed with a hand saw or power saw without specialty tooling.
