3 inch PVC DWV 22-1/2 Degree Street Elbow Fitting x Plastic

3” PVC 22.5° Elbow – Schedule 40 Fitting for Directional Adjustment in DWV Systems

The 3-inch PVC 22.5-degree elbow is designed for use in Schedule 40 drainage, waste, and vent (DWV) systems requiring a directional change of flow at a shallow angle. This fitting allows for gradual alignment shifts in piping layouts while maintaining optimal hydraulic performance in non-pressurized applications.

Manufactured from polyvinyl chloride (PVC) in compliance with ASTM D2466, this socket-end elbow connects to compatible pipe segments via solvent-weld joints, offering long-term joint integrity and resistance to corrosion, scaling, and chemical degradation common in DWV service conditions.

Product Specifications

• Material: PVC Type I (per ASTM D1784, Cell Class 12454)
• Nominal Size: 3 inches
• Angle: 22.5 degrees
• Connection Type: Socket x Socket (solvent weld)
• Standard Compliance: ASTM D2466 for Schedule 40 fittings
• Application Rating: Gravity-fed DWV systems (non-pressurized)

Performance Characteristics

• ✅ Gradual Flow Redirection – Designed to reduce turbulence and maintain proper slope in horizontal and vertical transitions
• ✅ System Compatibility – Fits standard 3” Schedule 40 PVC piping used in residential and light commercial drainage installations
• ✅ Solvent Weld Joint Integrity – Bonds chemically with pipe to form a single leak-resistant structure
• ✅ Non-Metallic Durability – Resists internal scaling, rust, and most household and construction-related chemicals

Installation Guidelines

Use PVC primer and solvent cement as specified by local code and manufacturer recommendations. Clean and dry all mating surfaces prior to bonding. Allow adequate curing time before system pressure or drainage testing. This fitting is not suitable for hot water or continuous pressurized service.

Common Applications

The 22.5° elbow is often installed in branch or mainline drainage runs to accommodate site-specific elevation changes or fixture alignment constraints. It is used in slab penetrations, vent offsets, and long horizontal piping routes where gradual redirection is required for code-compliant flow.

Material Note

Schedule 40 PVC is widely used in DWV systems for its low weight, ease of fabrication, and resistance to internal abrasion and biological buildup. It remains stable up to approximately 140°F (60°C) in intermittent service conditions.

The 3” PVC 22.5-degree elbow is a critical component for gravity drainage systems requiring long-lasting, low-maintenance directional transitions that conform to current code requirements.
