1-1/2 inch Copper Return Bend – DWV CxC Fitting for Drainage Systems

The 1-1/2 inch Copper DWV Return Bend CxC is a specialized fitting designed to create a 180-degree change in direction within drain, waste, and vent systems. Featuring copper solder (CxC) connections on both ends, this fitting is fabricated in accordance with ANSI/ASME B16.23 and is suitable for soldered copper tubing used in DWV applications.

Constructed from lead-free wrought copper (Alloy C12200), this return bend offers excellent corrosion resistance, thermal stability, and longevity in low-pressure, non-potable systems. Its design supports smooth directional flow and facilitates tight-radius piping configurations, commonly required in confined installation areas.

Technical Specifications

• ✅ Nominal Size: 1-1/2 inch
• ✅ Connection Type: CxC (sweat solder connections)
• ✅ Material: Wrought copper, alloy C12200 (deoxidized, phosphorus-bearing)
• ✅ Standards Compliance: ANSI/ASME B16.23 and ASTM B75/B88
• ✅ Application: DWV (drain, waste, vent) systems – gravity-fed, non-pressurized

Common Applications

This return bend is designed for use in horizontal or vertical DWV piping runs where a compact, 180-degree directional change is needed. It is typically installed in:

• ✅ Residential and commercial drainage systems
• ✅ Behind-wall configurations with limited turning radius
• ✅ Multi-story stack systems and fixture branches

Installation Guidelines

For proper installation, clean and flux all soldered surfaces before assembly. Use lead-free plumbing solder conforming to local and national codes. Allow adequate clearance for thermal expansion and avoid applying direct mechanical stress to the fitting. This return bend is designed for non-pressurized systems and should not be used in potable water supply lines or pressurized service unless specifically rated.

Performance Features

• ✅ Lead-Free Construction: Complies with NSF/ANSI 61 and 372 for use in non-potable systems
• ✅ High Corrosion Resistance: Copper alloy maintains long-term integrity in acidic and neutral pH environments
• ✅ Consistent Wall Thickness: Promotes uniform heat distribution during soldering
• ✅ Compact Radius: Suitable for installations requiring minimized spacing between piping offsets

Regulatory Note

This copper DWV fitting meets U.S. Safe Drinking Water Act lead-content standards for lead-free materials, although it is specifically intended for use in non-potable drainage and venting systems as defined by the IPC and UPC codes.

The 1-1/2 inch Copper Return Bend DWV CxC is a durable and code-compliant solution for directional changes in gravity drainage systems. Its clean design, ease of installation, and long service life make it a preferred component for professional-grade DWV installations in both residential and commercial construction.
