The CHARLOTTE PIPE D123040 is a 4-inch PVC DWV hub adapter designed for drain, waste, and vent piping systems. This fitting connects hub-end pipe to spigot-end pipe in non-pressure, gravity-fed waste elimination systems. Rated for temperatures up to 140 degrees F, PVC construction keeps the fitting lightweight and straightforward to handle on the job. Licensed plumbers and pipefitters install this adapter in residential and light commercial DWV applications where a reliable hub-to-spigot transition is required.
This adapter is suited for gravity-fed drain, waste, and vent systems in residential and commercial construction. It accepts solvent cement joining, threading, flanging, or roll-grooved joining methods, giving installers flexibility depending on the existing piping configuration. The 4-inch size fits standard DWV trunk lines and branch connections commonly found in bathroom, kitchen, and utility drain rough-ins.
Designed as an OEM-style replacement fitting for 4-inch PVC DWV drain, waste, and vent piping systems in non-pressure, gravity-fed applications.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is fully drained before beginning work. When solvent cementing, use a PVC-rated primer and cement appropriate for DWV fittings and allow full cure time before restoring flow. Do not use this fitting in pressurized supply lines or in systems where operating temperatures exceed 140 degrees F.
