3-Inch ABS DWV Wye – Precision-Fit Fitting for Optimized Drainage Flow

The 3 inch ABS DWV Wye is a fundamental component used in gravity-fed drain, waste, and vent systems. Designed to create a 45-degree branch connection from a vertical or horizontal main line, this fitting enables directional changes without compromising flow efficiency or system integrity. Its seamless integration into existing ABS piping systems makes it ideal for new construction and renovation projects alike.

Key Advantages

• ✔️ Injection-Molded ABS – Constructed from high-strength Acrylonitrile Butadiene Styrene for durability, dimensional stability, and excellent impact resistance.
• ✔️ Standard Hub Connections – Designed for solvent-weld joining using ABS cement, ensuring a strong, permanent seal that meets plumbing code requirements.
• ✔️ 45° Branch Angle – Reduces flow resistance and supports smooth transition of wastewater, decreasing the likelihood of blockages.
• ✔️ Code-Compliant Design – Manufactured to conform with ASTM D2661 and D3965 standards for ABS DWV fittings.
• ✔️ Lightweight and Corrosion-Resistant – Easy to handle and install, even in confined spaces, with no risk of rust or scale formation.

Technical Specifications

• Material: ABS (Acrylonitrile Butadiene Styrene)
• Nominal Size: 3 inches
• Branch Angle: 45 degrees
• End Connection: Hub x Hub x Hub
• Compliance: Meets or exceeds ASTM D2661, CSA B181.1

Typical Applications

This fitting is used to connect a branch line into a main DWV line at a smooth angle, which facilitates efficient wastewater flow. It is suitable for residential, multi-family, and light commercial systems involving bathrooms, kitchens, and utility drains. The 3 inch wye is especially effective when used to branch vent stacks or horizontal waste arms from the main soil or waste stack.

Installation Considerations

Solvent welding requires clean, properly prepared pipe ends and ABS solvent cement that complies with local code. For optimal results, dry-fit the assembly before final bonding to ensure proper alignment. Proper fall and orientation of the wye fitting should be maintained to comply with drainage codes.

Did You Know?

In DWV systems, 45-degree wyes are often preferred over sanitary tees for horizontal-to-horizontal connections because they reduce turbulence and preserve laminar flow—helping to prevent clogs and improve system performance.

The 3-Inch ABS DWV Wye is a dependable fitting that ensures long-term performance and code-compliant configurations. For professional-grade drainage installations, this component delivers precision, flow efficiency, and structural integrity you can rely on.
