2 inch x 1-1/2 inch PVC DWV Reducing Wye – Engineered for Drainage and Vent Systems

The 2 inch x 1-1/2 inch PVC DWV (Drain-Waste-Vent) reducing wye is a solvent-weld fitting designed to facilitate directional transitions between branch and main lines in non-pressurized drainage systems. It enables a smooth reduction from a 2-inch run to a 1-1/2 inch branch at a 45° angle, ensuring efficient waste removal and airflow within the piping network.

This fitting is molded from rigid polyvinyl chloride (PVC) and is intended for use in sanitary DWV applications. Its design promotes unobstructed flow while maintaining the structural integrity required for long-term residential and commercial use under gravity flow conditions.

Technical Advantages

• ✅ High-Impact PVC Resin Resistant to corrosion, scaling, and chemical degradation typical in drainage environments.
• ✅ Slip Connection Ends Compatible with standard Schedule 40 DWV piping for solvent-weld joints.
• ✅ Reduced Turbulence 45° branch entry optimizes flow dynamics and minimizes the risk of clogging at junctions.

Specifications

• Main Line Size: 2-inch nominal
• Branch Size: 1-1/2 inch nominal
• Configuration: Reducing Wye, 45-degree angle
• Material: PVC (Polyvinyl Chloride), Schedule 40
• Standards: Complies with ASTM D2665 and NSF 14 for DWV systems

Installation Guidance

Solvent welding is required using ASTM F656 primer and F656/F493 cement. Ensure pipe ends are properly deburred and fully seated to the fitting socket to achieve a leak-free joint. Follow regional plumbing codes and installation best practices for vertical and horizontal drain configurations.

Typical Applications

Commonly used in residential and light commercial DWV systems to join a smaller branch line into a larger drain line at an angle. Suitable for waste and vent routing in vertical stacks, crawlspace piping, or slab rough-ins.

Material Note

PVC DWV fittings are lightweight, non-conductive, and immune to rust and corrosion—advantages that contribute to reduced labor during handling and long service life in underground or above-grade installations.

The 2 inch x 1-1/2 inch PVC DWV reducing wye is a code-compliant solution for directional transitions in gravity-fed systems, supporting system performance while meeting dimensional and material standards required in professional plumbing installations.
