3 inch x 2 inch ABS DWV Reducing Sanitary Tee – Engineered for Code-Compliant Drainage Transitions

The 3 inch x 2 inch ABS DWV Reducing Sanitary Tee is designed for use in non-pressurized drainage, waste, and vent systems. This fitting facilitates directional flow and diameter transition in vertical stacks or horizontal drain lines, supporting efficient wastewater movement while maintaining structural integrity and code compliance.

Manufactured from high-impact Acrylonitrile Butadiene Styrene (ABS), this tee offers excellent dimensional stability, chemical resistance, and ease of solvent welding. It is suitable for both residential and light commercial DWV applications, including new installations and retrofit scenarios requiring diameter reduction without compromising flow efficiency.

Performance and Structural Advantages

• ✅ Injection-Molded ABS Construction – Lightweight yet rigid material resists deformation and impact during installation and service.
• ✅ One-Piece Reducing Tee – Factory-formed for precise fitment, eliminating the need for field modification or bushings.
• ✅ Socket-Type Hub Connections – Designed for solvent cement bonding to ensure secure, leak-free joints that meet plumbing code standards.
• ✅ Optimized Internal Geometry – Smooth interior contours reduce flow resistance and mitigate clogging risk in multi-branch drainage systems.

Specifications

• Material: ABS (Cell Class 32222 per ASTM D3965)
• Nominal Size: 3 inch x 2 inch
• Type: Reducing Sanitary Tee, Hub x Hub x Hub
• Compliance: ASTM D2661, CSA B181.1
• System Use: DWV (Drainage, Waste, and Vent)

Installation Guidance

This fitting is intended for solvent-welded ABS DWV systems. Use approved ABS cement and follow local plumbing codes for curing time, orientation (sweep direction), and joint inspection. Ensure cuts are square and deburred prior to assembly to achieve full bond strength and prevent joint failure.

Applications

The 3 inch x 2 inch ABS Reducing Sanitary Tee is used where branch lines of smaller diameter connect to larger main waste or vent piping. Typical use cases include bathroom group rough-ins, kitchen sink drains, and vent stacks requiring space-efficient branch integration with proper fall and flow control.

Contractor Insight

ABS is often selected over PVC for DWV systems due to its lower installation weight, absence of primer requirement, and strong resistance to a range of domestic and industrial waste streams. It is commonly specified in slab, wall, or overhead applications where speed of assembly and durability are priorities.

The 3 inch x 2 inch ABS DWV Reducing Sanitary Tee delivers dependable performance where transitions in pipe sizing are required. Engineered for efficiency, durability, and compliance, it is a trusted component in professional DWV system installations.
