1-1/2 inch PVC Double Tee – DWV Fitting for Drainage Applications

The 1-1/2 inch PVC double tee is designed for use in non-pressurized drain, waste, and vent (DWV) systems where dual branch connections are required. Molded from schedule 40 polyvinyl chloride (PVC), this fitting provides a corrosion-resistant and code-compliant solution for horizontal piping configurations in residential and light commercial environments.

Manufactured in accordance with ASTM D2665 standards, this component features solvent-weld hub ends to ensure permanent, watertight joints when properly installed with PVC primer and solvent cement. The double tee design facilitates the integration of two perpendicular lateral lines into a continuous main run, helping to maintain balanced flow and adequate system ventilation.

Key Functional Features

• ✅ DWV System Compatibility – Suitable for gravity-fed drain and vent applications only; not for pressurized systems.
• ✅ Standard Hub x Hub x Hub x Hub Configuration – Accepts 1-1/2 inch nominal PVC pipe for solvent welding.
• ✅ Durable Material – Constructed from rigid, chemical-resistant PVC for long service life and minimal maintenance.
• ✅ Smooth Flow Channels – Designed to minimize turbulence and promote uninterrupted waste removal and air flow.
• ✅ ASTM D2665 Compliance – Tested and certified to conform to plumbing industry requirements for DWV applications.

Technical Specifications

• Nominal Size: 1-1/2 inch (all inlets and outlets)
• Configuration: Double tee with four solvent weld hubs
• Material: Schedule 40 PVC
• Application: Drainage, waste, and vent systems (non-pressurized)
• Standards: ASTM D2665, NSF 14

Installation Considerations

Install using approved PVC primer and solvent cement. All cuts must be square, and pipe ends should be clean and deburred before assembly. Observe proper alignment and pipe support per applicable code requirements. This fitting is intended for horizontal installations and is typically placed behind walls or within floor systems.

Common Use Cases

Used primarily in residential branch line layouts, the PVC double tee provides connection points for sinks, tubs, or other fixtures discharging into a shared drainage line. It is particularly effective in stack offset arrangements and service wet-venting systems.

Material Performance Insight

Schedule 40 PVC is lightweight, easy to cut and join, and resistant to most household and construction-related chemicals. Its thermal and structural properties make it well-suited for gravity-fed waste systems where longevity and low maintenance are required.
