The CHARLOTTE PIPE PVC-102-4X6 is a PVC DWV increaser reducer coupling designed to transition between 4-inch and 6-inch drain, waste, and vent pipe runs. This fitting is engineered for gravity-fed, non-pressure drainage systems in residential and commercial construction. PVC construction keeps the fitting lightweight and corrosion-resistant. The part is rated for system temperatures not exceeding 140 degrees F. Licensed plumbers and pipefitters install this coupling as part of below-grade or above-grade DWV assemblies where pipe diameter changes are required along the drainage stack or branch lines.
This increaser reducer fits standard PVC DWV piping systems and is suited for residential homes, multi-family buildings, and light commercial projects. It is commonly used where a 4-inch branch line ties into a 6-inch main drain stack, or where a drain line expands to accommodate increased flow volume. The fitting accepts solvent cement joining, which is the standard installation method for PVC DWV systems. No special cutting tools are required to prepare the pipe ends for this connection.
Designed as an OEM-style replacement or new-installation fitting for standard 4-inch by 6-inch PVC DWV piping systems in non-pressure gravity drainage applications.
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 drain line is depressurized before cutting into an existing system. Clean and dry both pipe ends, then apply PVC primer and solvent cement per the cement manufacturer's instructions before joining. Do not subject this fitting to pressurized flow or temperatures above 140 degrees F.
