2 inch Copper DWV 22-1/2° Elbow – Drainage Fitting for Directional Change

The 2 inch Copper DWV 22-1/2° Elbow is a drainage fitting designed to facilitate smooth directional transitions in drain, waste, and vent systems. Its 22.5-degree angle allows for gentle directional adjustments within horizontal DWV copper piping runs, reducing the risk of flow restriction or turbulence.

Constructed from wrought copper and manufactured to applicable standards, this fitting provides corrosion resistance and mechanical integrity in both residential and commercial non-pressurized drainage applications. It is suitable for above-ground systems and is commonly joined using solder connections.

Application Benefits

• ✅ DWV-Specific Geometry – 22-1/2° angle designed to manage directional flow with minimal disruption.
• ✅ Non-Pressure Rated – Intended for gravity-fed systems in compliance with DWV plumbing layouts.
• ✅ Wrought Copper Construction – Resistant to scaling, microbial growth, and internal degradation.
• ✅ ASTM Compliance – Meets ASTM B75/B88 and ASME/ANSI B16.29 requirements for copper fittings.

Installation Considerations

Installation requires standard copper joining techniques using lead-free solder, flux, and a torch. Ensure surfaces are cleaned and prepped prior to soldering for optimal joint strength. This fitting is not intended for use in pressurized potable water systems. Verify all local code requirements before installation.

Common Uses

Frequently utilized in horizontal DWV piping networks to adjust pipe direction while maintaining slope. Especially effective in space-constrained retrofits or when routing drain lines through joist bays or soffits.

Did You Know?

Copper DWV systems offer superior noise attenuation and longevity compared to many thermoplastic alternatives. Their fire-resistant properties and durability in high-temperature environments are especially advantageous in multi-unit dwellings and institutional projects.

This 2 inch Copper DWV 22-1/2° Elbow provides reliable function and compatibility in code-compliant drainage systems. Proper specification and installation are essential to achieving system performance and longevity.
