3 inch x 3 inch x 1-1/2 inch PVC DWV Reducing Wye Plastic x Plastic x Plastic

3” x 1-1/2” PVC Wye – Engineered for Efficient Drainage Branching

The 3” x 1-1/2” PVC Wye fitting is manufactured to ASTM D2665 and D3311 standards, ensuring performance and reliability in drain, waste, and vent (DWV) applications. This solvent-welded fitting provides a smooth directional transition from a 3-inch main line to a 1-1/2-inch branch, supporting optimal flow rates and system balance.

Its structural integrity and dimensional accuracy make it suitable for new construction or repair work in both residential and light commercial plumbing systems. The angled design promotes better drainage and reduces turbulence within the piping network.

Key Features and Benefits

• ✅ Conforms to ASTM D2665 and D3311 – Industry-recognized standards for PVC DWV fittings.
• ✅ Lead-Free and Non-Toxic – Safe for use in code-compliant drain and vent systems.
• ✅ Engineered for Smoother Flow – Angled wye configuration minimizes clogs and sediment buildup.
• ✅ Solvent Weld Connections – Designed for secure joints using PVC cement for permanent bonds.
• ✅ Lightweight, Rigid Construction – Easier handling and faster installation with excellent dimensional stability.

Technical Specifications

• Primary Size: 3 inch (main run)
• Branch Size: 1-1/2 inch
• Material: PVC Type I, Grade 1 (Cell Classification 12454 per ASTM D1784)
• Connection: Hub x Hub x Hub (Slip-fit for solvent weld)
• Compliance: Meets NSF Standard 14, UPC, IPC, and local building code requirements

Common Applications

This wye fitting is primarily used in DWV systems for horizontal to horizontal or horizontal to vertical transitions, such as connecting branch lines from kitchen sinks, tubs, or laundry standpipes into the main stack. Its compatibility with Schedule 40 piping systems makes it a standard component in residential and multi-unit construction.

Installation Considerations

Install using PVC solvent cement and primer per ASTM D2855 procedures. Ensure that both mating surfaces are clean and dry. Proper alignment during assembly is crucial for directional accuracy and maintaining code-compliant slope in DWV lines.

Code Note

Many local plumbing codes require the use of wyes, rather than tees, for horizontal drainage connections due to improved flow characteristics. This fitting satisfies those conditions and supports long-term system efficiency.

Specify the 3” x 1-1/2” PVC Wye when planning drainage systems that demand dependable branching with low flow resistance. Its durable construction, standardized sizing, and ease of installation make it a contractor-preferred choice for high-performance DWV layouts.
