1-1/4 inch PVC DWV Sanitary Tee – Hub x Hub x Hub for Drain, Waste & Vent Systems

The 1-1/4 inch PVC sanitary tee is a DWV (Drain, Waste, and Vent) fitting designed for branch connections in non-pressurized piping systems. Its configuration allows for a smooth directional change from a horizontal or vertical branch into a main line, while maintaining code-compliant venting and flow characteristics.

Manufactured from rigid polyvinyl chloride and meeting ASTM D2665 and NSF 14 standards, this fitting features hub connections on all three inlets and outlets for solvent-weld joints. It is intended for use in gravity-flow DWV systems as outlined in the International Plumbing Code (IPC) and Uniform Plumbing Code (UPC).

Fitting Features

• ✅ Nominal Size: 1-1/4 inch Hub x Hub x Hub
• ✅ Material: PVC Type I, Grade I (per ASTM D1784)
• ✅ Design: Sanitary tee with curved sweep for horizontal-to-vertical transitions
• ✅ Joining Method: Solvent-weld hub ends using PVC primer and cement
• ✅ Certifications: Complies with ASTM D2665, NSF 14, and CSA B181.2

Installation Considerations

This fitting must be installed using proper PVC cement and primer for DWV systems. Pipe ends should be square-cut, deburred, and fully inserted into hubs until seated. Sanitary tees are used only in non-pressurized applications and should not be substituted for long sweep elbows or wyes when horizontal drainage configuration is required by code.

Typical Applications

Commonly used in residential and light commercial plumbing systems, the 1-1/4 inch PVC sanitary tee is ideal for fixture drainage where smaller branch lines tie into a vertical or horizontal stack. It is suitable for use in wall cavities, floor spaces, or behind cabinetry where compact layout and reliable alignment are required.

Material Note

Schedule 40 PVC fittings are known for their high chemical resistance, rigidity, and compatibility with domestic wastewater conditions. This fitting is not intended for hot water or pressure applications but performs well in all standard DWV configurations up to 140°F (60°C) intermittently.
