4 inch PVC DWV 22-1/2 Degree Elbow Plastic x Plastic

4 inch 22-1/2 Degree PVC DWV Elbow – Engineered for Directional Flow Control

The 4 inch 22-1/2 Degree PVC DWV Elbow is specifically designed to facilitate gradual directional changes in drain, waste, and vent systems. Its shallow angle allows for smooth transitions in horizontal or vertical piping, helping maintain consistent flow rates and reducing turbulence in the line.

Performance Advantages for Professional Installations

• ✅ Injection-Molded PVC – Fabricated from high-strength polyvinyl chloride for corrosion resistance and dimensional stability.
• ✅ Shallow Sweep Design – 22.5° angle supports flow optimization in DWV systems, minimizing clogs and reducing the likelihood of hydraulic noise.
• ✅ Socket Ends (Hub x Hub) – Standard solvent weld sockets ensure compatibility with Schedule 40 DWV pipe, streamlining installation.
• ✅ Meets ASTM D2665 and D3311 – Manufactured to comply with applicable building and plumbing codes.

Technical Specifications

• Material: PVC (Polyvinyl Chloride)
• Size: 4-inch nominal diameter
• Angle: 22-1/2 degrees
• End Connections: Hub x Hub (solvent weld)
• Standards: ASTM D2665, D3311; NSF compliant for DWV use

Installation Overview

Designed for solvent weld connection using standard primer and cement, this elbow installs quickly with proper pipe preparation. Ensure alignment with drainage grade requirements and follow applicable plumbing code standards. Suitable for both new construction and retrofits.

Typical Applications

Frequently used in DWV system layouts to alter direction in long pipe runs or to align pipe with structural elements. Common in multi-story residential and commercial stacks, under-slab systems, or vent offsets where sharper turns would impede flow.

Did You Know?

Fittings with shallow angles like 22-1/2 degrees are often required by plumbing code for directional changes in horizontal drainage to maintain optimal slope and minimize stoppage potential.

The 4 inch 22-1/2 Degree PVC DWV Elbow is a vital component for properly engineered drainage layouts. With its code-compliant construction and reliable material performance, this fitting is built to support long-term system integrity in demanding environments.
