2 inch ABS DWV 22-1/2 Degree Elbow – Short-Radius Directional Fitting for DWV Systems

The 2 inch ABS DWV 22-1/2° Elbow is a solvent-weld fitting designed to facilitate directional changes in drain, waste, and vent (DWV) piping layouts. This fitting provides a smooth, low-angle redirection of flow, typically used to maintain hydraulic efficiency in horizontal runs or achieve grade adjustments in compact spaces.

Manufactured from Acrylonitrile Butadiene Styrene (ABS), this fitting offers impact resistance and ease of handling. It is engineered to conform to dimensional and performance specifications for non-pressurized DWV systems in residential and commercial construction.

Material and Design Characteristics

• ✅ Nominal Size: 2 inch (standard hub connections for ABS pipe)
• ✅ Fitting Angle: 22-1/2° (also known as 1/16 bend)
• ✅ Material: ABS thermoplastic – lightweight, non-corrosive, and suitable for indoor or above-grade applications
• ✅ Joining Method: Solvent weld (requires primer and cement per code)
• ✅ Compliance: Meets ASTM D2661 and CSA B181.1 standards

Installation Guidance

Prior to joining, both fitting and pipe should be dry-fitted to ensure proper alignment. Surfaces must be clean and squarely cut. Use an approved ABS solvent cement and, if required by local code, an appropriate primer. Apply cement evenly and insert pipe fully with a quarter-turn twist to ensure bond strength. Allow adequate curing time based on temperature and pipe diameter.

Applications

Commonly installed in DWV systems within residential structures, this 22-1/2° elbow is used in stack offsets, directional transitions beneath slabs, and vent reroutes behind framing. It supports gradual changes in flow direction to reduce turbulence and promote consistent system drainage.

Material Performance

ABS offers high impact resistance and dimensional stability. It is chemically resistant to many household waste products and performs reliably across a broad range of ambient temperatures. This material is not recommended for direct sunlight exposure unless UV-stabilized or properly shielded.

Installation Considerations

Though this fitting is straightforward to install, precision is essential to avoid grade misalignment in gravity-fed systems. Support piping per code to prevent joint stress. In multi-story or critical layout environments, layout accuracy and inspection-readiness are essential for passing code review.

The 2 inch ABS DWV 22-1/2° Elbow is a standard component in code-compliant drainage installations where smooth redirection of flow is needed. It supports efficient layout of horizontal and vertical DWV assemblies in accordance with national plumbing standards.
