3 inch x 3 inch x 1-1/2 inch PVC DWV Reducing Wye for Gravity Drainage Systems

The 3 Inch x 3 Inch x 1-1/2 Inch PVC DWV Reducing Wye is designed to join a branch line at a 45-degree angle to a larger horizontal drain or waste run, facilitating smooth directional flow and maintaining system venting integrity. Commonly used in gravity-fed sanitary drainage and vent systems, this fitting supports transitions between main and reduced branch lines with minimal flow restriction.

Professional-Grade Characteristics

This reducing wye is injection molded from high-quality polyvinyl chloride (PVC) and conforms to ASTM D2665 standards for use in DWV (Drain, Waste, and Vent) systems. The configuration enables effective wastewater redirection in vertical and horizontal layouts while preserving laminar flow.

• ✅ Code-Compliant Geometry 45° branch reduces turbulence and backflow risk at junction points.
• ✅ Hub Connections Compatible with solvent weld joints for a chemically bonded, leak-resistant seal.
• ✅ Corrosion-Resistant Construction Engineered for longevity in non-pressurized interior drainage systems.
• ✅ Thermal Stability Rated for temperatures consistent with DWV system performance parameters.
• ✅ Adaptable Configuration Allows for reduction from a 3 inch main to a 1-1/2 inch lateral without additional bushings or adapters.

Installation Notes

For solvent welding, use primer and cement approved for PVC DWV installations. Proper pipe preparation—cleaning, deburring, and dry-fitting—is essential for ensuring system integrity. Refer to IPC/UPC code requirements for branch sizing, slope, and cleanout access.

Common Applications

This reducing wye is frequently installed in multi-branch waste systems where space constraints require direct reduction and redirection. Examples include lavatory tie-ins, vented fixture group layouts, and back-to-back fixture configurations in vertical stacks.

Material and Flow Consideration

PVC DWV fittings are engineered to maintain smooth interior surfaces, minimizing resistance and supporting self-scouring flow rates within gravity-fed drain systems. The 1-1/2 inch branch provides compatibility with standard residential fixture branches including sinks and tubs.

Specify the 3 inch x 3 inch x 1-1/2 inch PVC DWV Reducing Wye for cost-effective, code-compliant transitions within sanitary drainage layouts. Its dimensional precision and material consistency ensure long-term performance under expected system loads.
