Westlake Pipe Fittings dwv-d100-030 Pvc Dwv Coupling 3 in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d100-030 is a Schedule 40 PVC drain-waste-vent (DWV) coupling designed to join two sections of 3-inch pipe in gravity-flow drain systems. The fitting features a hub-by-hub (H x H) configuration, meaning both ends accept pipe into a socket end for solvent-welded connections. It is manufactured to Schedule 40 wall thickness standards, making it suitable for residential and light commercial DWV applications. Licensed plumbers and pipefitters install this fitting during rough-in and repair work on soil, waste, and vent lines.

This coupling is used in drain, waste, and vent piping systems where two lengths of 3-inch PVC pipe must be joined in a straight run. Common install scenarios include new construction rough-in, repair splices on existing drain lines, and extensions to branch drain runs. The H x H end configuration allows standard hub-socket solvent cement joints on both sides, consistent with Schedule 40 PVC DWV assembly practices.

Key Features

• Hub x Hub (H x H) end connections on both sides for solvent-cement socket joints
• Schedule 40 wall thickness for standard DWV service
• 3-inch nominal pipe size fits standard 3-inch PVC DWV pipe
• PVC material resists corrosion and chemical attack in drain service
• Rated for drain, waste, and vent (DWV) applications

Compatibility

Designed as an OEM-style replacement and standard fitting for 3-inch Schedule 40 PVC DWV piping systems in residential and light commercial drain, waste, and vent installations.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local authority having jurisdiction (AHJ) requirements. Before cutting into an existing drain line, isolate flow and ensure the line is clear. Solvent-cement joining requires the proper PVC primer and cement applied per manufacturer instructions and ASTM D2564 guidelines. Do not apply heat or mechanical force to seat the joint — solvent welding is the only approved method for Schedule 40 PVC DWV hub connections.
