Westlake Pipe Fittings dwv-d443-040 Dwv Pvc Cleanout Tee 4in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d443-040 is a 4-inch DWV PVC cleanout tee fitting supplied with a cleanout plug. It is designed for drain, waste, and vent piping systems in residential and commercial plumbing installations. The fitting is molded from PVC and is rated to a maximum service temperature of 140 degrees F. Hub by hub end connections allow the fitting to be solvent-cemented directly into existing DWV pipe runs. The included cleanout plug provides accessible cleanout capability without requiring a separate fitting. This fitting meets ASTM D 3311, ASTM 1866, and ASTM 1784 standards and carries NSF 14 certification.

This fitting is used in gravity-drain and vent piping applications where an accessible cleanout point is required. Typical installations include main drain lines, branch drain lines, and vent stacks in residential and light commercial construction. The 4-inch size suits main building drain lines and primary horizontal runs. Licensed plumbers and journeyman pipefitters install this fitting during rough-in or as a retrofit cleanout access point on existing DWV systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the drain line is depressurized before cutting into an existing line. Use approved PVC primer and solvent cement rated for DWV applications and allow full cure time before restoring flow. Do not expose PVC DWV fittings to sustained temperatures above the rated maximum or to solvent contact from incompatible chemicals.
