1-1/2 Inch Copper DWV 45 Degree Elbow – Wrot Copper Fitting for Drainage Systems

This 1-1/2 inch copper 45° elbow is a Drainage, Waste, and Vent (DWV) fitting designed to redirect horizontal flow in copper DWV piping systems. Constructed from wrot copper, this fitting is engineered to meet ASTM and NSF standards for non-pressurized drainage applications where smooth directional changes are necessary.

Fitting Characteristics

• ✅ Material: Wrot copper (lead-free, per ASTM B75 and B88)
• ✅ Angle: 45 degrees for gradual directional change in piping layout
• ✅ Connection Type: Cup (female sweat) x Cup – designed for soldered joints
• ✅ Nominal Size: 1-1/2 inch
• ✅ Application: Non-pressure DWV systems only

Code Compliance and Manufacturing Standards

• ✅ Standard: Conforms to ASME B16.29 and applicable sections of ASTM B306 for DWV copper fittings
• ✅ Lead-Free Certification: Meets the Safe Drinking Water Act (SDWA) criteria for lead-free plumbing components
• ✅ Joining Method: Soldered connection using ASTM B813-compliant flux and lead-free solder

Installation Guidance

Ensure all pipe ends and fitting cups are cleaned and reamed prior to assembly. Use approved flux and solder suitable for DWV applications. This fitting is not intended for pressurized service. Proper slope (typically 1/4 inch per foot) must be maintained to comply with code and ensure gravity flow.

Use in horizontal waste arms, branch lines, or vent offsets where a smoother transition is preferred over 90° elbows. Avoid use in applications involving potable pressurized water or mechanical piping subject to high pressure or thermal expansion unless approved for dual-use under local code.

Typical Use Cases

• Horizontal transitions in residential copper DWV systems
• Vent stack offsets in wall cavities or chase areas
• Drainage re-routing during remodel or retrofit projects

Material Advantages

Wrot copper fittings offer a long service life and corrosion resistance in air and moisture-rich environments typical of DWV systems. Their consistent inner surface diameter also promotes unobstructed drainage and venting performance.
