4 Inch x 4 Inch x 3 Inch PVC DWV Reducing Sanitary Tee – Engineered for Code-Compliant Transitions

The 4 inch x 4 inch x 3 inch PVC DWV Reducing Sanitary Tee is designed for efficient transitions in drain, waste, and vent systems where reduction in branch size is required. Manufactured from durable polyvinyl chloride, this fitting ensures proper flow alignment and joint integrity in gravity-fed systems.

Key Functional Attributes

• ✅ Standard-Conforming Design Manufactured in accordance with ASTM D2665 and D3311 standards for DWV systems, ensuring dimensional accuracy and code compliance.
• ✅ Corrosion and Chemical Resistance The PVC construction resists scale buildup and degradation from household effluents and corrosive environments.
• ✅ Slip Joint Configuration Socket-style hub ends allow for solvent-weld connections, providing a permanent, leak-resistant joint suitable for horizontal and vertical applications.
• ✅ Optimized Flow Path Sanitary tee configuration directs flow in accordance with hydraulic principles for minimal turbulence and reduced clog potential.
• ✅ Reduced Maintenance Risk Proper joint assembly significantly reduces the likelihood of callbacks due to joint failure or misalignment under normal service conditions.

Installation Considerations

This fitting is intended for use in non-pressurized DWV systems and should be installed using appropriate primer and solvent cement per ASTM F656 and F493. Ensure that piping is properly deburred and inserted fully into socket ends. Alignment and slope per UPC/IPC code should be verified prior to solvent setting. Recommended for use by licensed professionals.
