3 inch x 1-1/2 inch PVC Double Sanitary Tee – Designed for DWV System Efficiency

The 3 inch x 1-1/2 inch PVC Double Sanitary Tee is engineered to support efficient drainage transitions in horizontal and vertical DWV (Drain, Waste, Vent) applications. This fitting enables two 1-1/2 inch branch lines to enter a 3 inch main line at opposing angles, facilitating smooth wastewater flow while maintaining system balance and accessibility.

Manufactured from durable polyvinyl chloride (PVC) and designed to meet rigorous dimensional tolerances, this double tee supports long-term performance in both new construction and retrofit scenarios. It complies with ASTM D2665 standards for use in non-pressurized waste systems and is compatible with solvent-welded joint assemblies.

Performance Features

• ✅ High-Capacity Design Dual inlets enable simultaneous service from multiple fixtures into a common main line.
• ✅ Corrosion and Chemical Resistance PVC material resists degradation from domestic waste and cleaning chemicals.
• ✅ Thermal Stability Maintains shape and structural integrity within normal residential and commercial DWV temperature ranges.
• ✅ Hub Connections Socket-style inlets and outlet for solvent cement bonding to Schedule 40 DWV pipe.
• ✅ Code-Conforming Construction Fabricated to meet relevant standards for sanitary drainage systems, including UPC and IPC code compliance.

Installation Considerations

This fitting is installed using solvent cement in accordance with manufacturer and code guidelines. Proper pipe deburring, cleaning, and primer application are required for leak-free joints. Orientation must allow for gravity-assisted flow and proper venting to avoid system blockages. Refer to local code for installation in horizontal lines or when vented sweep angles are required.

Applications

The PVC double tee is commonly utilized in residential and light commercial waste systems to tie two branch lines into a central drain. It’s suitable for use in bathroom groups, kitchen lines, or utility connections where compact fittings are needed and service access is a consideration.
