Westlake dwv-d503-040 4 Inch Dwv Pvc Combo Wye 1/8 Bend

Product Description

The WESTLAKE PIPE FITTINGS dwv-d503-040 is a two-piece PVC combination wye and 1/8 bend fitting designed for drain, waste, and vent (DWV) piping systems. It features hub ends on all connections for solvent-welded joints and is sized at 4 inches nominal pipe size. The fitting meets ASTM D 3311, ASTM 1866, and ASTM 1784 standards and carries NSF 14 certification, making it suitable for use in code-compliant residential and commercial DWV installations. Licensed plumbers and pipefitters install this fitting when a combined direction change and branch connection is needed in a gravity-drain layout.

This fitting is suited for 4-inch DWV applications in residential and light commercial plumbing systems. The two-piece construction simplifies installation in tight or retrofit situations where a one-piece fitting may be difficult to maneuver into place. The hub-end configuration accepts standard 4-inch PVC pipe and is compatible with solvent-cement assembly per standard DWV practice. It is commonly used at branch junctions in soil stacks, horizontal drain lines, and underground drain piping.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the drain line is clear before cutting into an existing system. Clean and prime all hub ends before applying solvent cement, and allow adequate cure time before restoring flow. Do not use this fitting on pressurized supply lines.
