1-1/2" Copper DWV Wye – CxCxC Fitting for Sanitary Drainage Systems

The 1-1/2" Copper DWV Wye is a solder-joint drainage fitting used in copper drain, waste, and vent (DWV) piping systems to facilitate a branch connection at a 45° angle. Fabricated from lead-free wrought copper, this fitting allows for smooth redirection of waste flow, improving system hydraulics and reducing flow resistance compared to sanitary tees in horizontal piping.

Its three copper solder cup ends are dimensioned in accordance with ASME B16.29, making it compatible with standard copper DWV tubing. This fitting is approved for use in non-pressurized drainage applications governed by plumbing code requirements.

Key Product Attributes

• ✅ Material: Wrought copper (typically Alloy C12200), lead-free per NSF/ANSI 61 & 372
• ✅ Configuration: 45° Wye with three solder cup (CxCxC) ends for branch-line integration
• ✅ Application: Low-pressure DWV systems only; not rated for pressurized water distribution
• ✅ Fitting Standard: Manufactured to ASME B16.29 for DWV fittings in sizes 1-1/4" to 8"
• ✅ Corrosion Resistance: Copper construction offers excellent resistance to most domestic wastewater conditions

Installation Requirements

Install using standard soldering procedures for copper tubing. Pipe ends and fitting sockets must be cleaned and fluxed prior to heating. Use lead-free solder per applicable code requirements. Joint alignment should be confirmed prior to heat application to ensure proper branch angle and flow direction. Do not use in systems subject to continuous pressure or high-velocity flow.

Common Use Cases

The 1-1/2" DWV Wye is typically installed in horizontal branch lines to connect fixture drains or vent lines to the main stack or lateral. Applications include residential bathrooms, kitchens, and utility connections requiring code-compliant drainage layout. Its geometry promotes smooth laminar flow and minimizes clog potential.

Regulatory Compliance

This fitting is certified as lead-free under federal and state plumbing codes and complies with NSF/ANSI 61 and 372 for potable water applications (if applicable). It also meets the International Plumbing Code (IPC) and Uniform Plumbing Code (UPC) requirements for DWV system fittings.

The 1-1/2" Copper DWV Wye is a durable, long-radius drainage fitting engineered for use in gravity-fed piping systems. Designed to support smooth flow transitions and maintain system performance in code-compliant copper DWV applications.
