2 inch x 1-1/2 inch ABS DWV Reducing Sanitary Tee – For Drainage and Venting Applications

The 2 inch x 1-1/2 inch ABS DWV Reducing Sanitary Tee is a solvent-weld fitting used to join a 2-inch horizontal drain line to a 1-1/2-inch vertical branch in non-pressurized plumbing systems. Engineered for gravity-flow drainage, this fitting supports directional changes while maintaining system efficiency and code compliance.

Constructed from impact-resistant ABS (acrylonitrile butadiene styrene), the tee is suitable for residential and light commercial drain, waste, and vent applications. It is commonly installed in vertical stacks, bathroom fixture connections, or any system requiring a transition from a larger to smaller pipe diameter.

Performance Characteristics

• Material: ABS – lightweight, rigid, and suitable for non-pressure DWV systems
• Configuration: 2 inch x 1-1/2 inch hub x hub x hub reducing tee
• Angle: 90-degree center outlet with a downward sweep for proper flow alignment
• Joining Method: Solvent-weld (meets ASTM D2661 and D3311 standards)
• Code Compliance: NSF-dwv certified; suitable for UPC and IPC plumbing code applications

Installation Guidelines

Install using a two-step ABS solvent cement process: apply primer (if required by local code), followed by ABS cement on both the fitting socket and pipe spigot. Insert to full depth with a quarter-turn twist. Cure time depends on ambient temperature and pipe size.

Applications

• Bathroom fixture tie-ins (e.g., lavatory or tub to main stack)
• Horizontal-to-vertical branch transitions
• Vent line routing in multi-fixture systems

Additional Notes

This fitting is not intended for pressurized systems or potable water distribution. For vertical vent-to-horizontal drain transitions, a wye or combination wye and 1/8 bend should be used per code. Verify all installation conforms with local and national plumbing regulations.
