3 inch x 2 inch PVC Double Sanitary Tee – DWV P x P x P Configuration

The 3 inch x 2 inch PVC Double Sanitary Tee in a P x P x P (hub x hub x hub) configuration is designed for use in non-pressurized drain, waste, and vent (DWV) systems. This fitting enables the connection of two horizontal branch lines into a main vertical drain line, reducing from 3 inch to 2 inch where required. Manufactured from schedule 40 PVC, it offers excellent chemical and corrosion resistance while maintaining dimensional stability under DWV system loads.

Engineered to meet ASTM D2665 and D3311 specifications, this tee provides reliable performance in both residential and light commercial drainage systems. The solvent weld hub ends ensure secure, leak-resistant joints when properly installed using approved primer and cement. Its dual-side inlets facilitate symmetrical or offset configurations based on jobsite layout.

Installation Guidance

This PVC double tee should be installed with a proper solvent cement and primer system compatible with PVC. Joint alignment and pipe insertion depth are critical for maintaining slope and flow efficiency. Adequate support and bracing per local plumbing codes will help prevent joint stress and ensure system longevity. Avoid use in applications exposed to UV or high temperatures without protective measures.

Typical Applications

The 3 inch x 2 inch PVC DWV double sanitary tee is used in vertical drainage stacks where multiple fixture drains or vents converge. Common in single-family and multi-family residential builds, it supports efficient layout in wall cavities and floor spaces with limited clearance, especially when reducing branch lines to 2 inch.

Technical Note

PVC DWV fittings are preferred in many building codes due to their high flow efficiency, ease of installation, and resistance to scale buildup and biological growth. This makes them especially well-suited for modern drainage design in both new and retrofit applications.

Use the 3 inch x 2 inch PVC Double Sanitary Tee where flow performance and code compliance are critical. Its dimensional accuracy, reliable weld joints, and long service life provide professional-grade results in every installation.
