3 inch PVC DWV Double Tee (Hub x Hub) – Built for Multi-Branch Drainage Systems

The 3 inch PVC DWV Double Tee fitting is engineered for use in sanitary drainage and vent systems where multiple lateral branches need to be connected to a vertical stack. Constructed from high-quality Schedule 40 PVC, this double tee offers reliable alignment and dimensional stability under normal gravity drainage conditions.

Featuring socket (hub) connections on all four outlets, the fitting supports solvent weld joints and complies with ASTM D2665 and D3311 specifications. It is designed for non-pressure DWV systems, providing dependable long-term performance with reduced installation time and minimized risk of misalignment or joint failure.

Product Advantages

• Nominal Size: 3 inch x 3 inch x 3 inch x 3 inch (four socket ends)
• Configuration: Double sanitary tee – horizontal inlets at 90°, with vertical run
• Material: PVC Type 1, Grade 1 per ASTM D1784, Cell Classification 12454
• Application: Drainage, waste, and vent systems (not for pressure use)
• Standards: Conforms to ASTM D2665, CSA B181.2, and meets UPC and IPC requirements

Installation Guidelines

Install using solvent cement and primer formulated for Schedule 40 PVC. Ensure pipe ends are square-cut and properly deburred before assembly. Double tees should be positioned so the horizontal branches connect laterals to the vertical drain per code requirements—typically not used for directional flow but for symmetrical branch connections.

Common Applications

• Vertical stacks with opposing horizontal branch inlets
• Multistory residential or light commercial DWV systems
• Bathroom group rough-ins where double fixtures need a shared vented stack

Important Consideration

Use of a double tee in a horizontal orientation (double fixture fitting) must comply with local code, which may require the use of a double combination wye and 1/8 bend in horizontal drainage to maintain proper flow characteristics.

The 3 inch PVC Double Tee (DWV) is a critical component for systems requiring multiple lateral tie-ins to a common stack. With its precise fit and durable construction, it helps contractors achieve long-lasting, code-compliant installations.
