2 inch PVC Double Sanitary Tee – Hub x Hub x Hub DWV Fitting

The 2 inch PVC Double Sanitary Tee is a solvent-welded drainage fitting designed for use in gravity-fed DWV (Drain, Waste, and Vent) systems. This fitting provides a branch connection at both sides of a main vertical stack, enabling symmetrical connections from two horizontal waste lines into a single vertical drainage path.

Technical Specifications

• Material: Polyvinyl Chloride (PVC Type I), Cell Classification 12454 per ASTM D1784
• Nominal Size: 2 inch
• Connection Type: Hub x Hub x Hub (solvent weld sockets)
• Configuration: Double tee pattern with a sanitary sweep radius
• Applicable Standard: Conforms to ASTM D2665 (DWV fittings), and certified to meet NSF/ANSI 14
• Operating Use: Non-pressurized systems only; not intended for potable or pressurized water service

Performance Characteristics

• ✅ Code-Compliant Geometry – Designed to facilitate proper drainage with smooth directional flow per UPC and IPC requirements
• ✅ Chemical and Corrosion Resistance – Suitable for typical household and commercial waste materials
• ✅ Impact Resistant – PVC provides strength and rigidity suitable for above-grade and below-grade installations
• ✅ Low-Profile Installation – Streamlined hub design fits standard 2 inch DWV pipe with solvent cement

Installation Guidelines

Install using approved PVC solvent cement in accordance with ASTM D2855. Pipe ends should be square-cut, deburred, and dry-fit prior to cement application. The double tee must be installed in a vertical stack with horizontal branches to ensure compliance with venting and drainage codes. Cleanout access or appropriate venting must be provided per local code.

Common Applications

Typically used in bathroom groups and back-to-back fixture installations, this fitting enables connection of lavatory, bathtub, or kitchen drains to a shared vertical drain line. It is also used in multi-unit residential layouts where space-efficient branching is required.

Material and Use Insight

PVC DWV fittings are favored for their ease of handling, corrosion resistance, and suitability for long-term drainage performance in both residential and commercial systems. Double sanitary tees should not be used for vent-to-drain transitions or in horizontal-to-horizontal configurations unless specifically permitted by code.

The 2 inch PVC Double Sanitary Tee is a code-compliant solution for dual-branch drainage integration in vertical stacks. Its solvent-weld connections and flow-efficient design support reliable performance in waste and vent systems constructed to industry standards.
