2 inch x 1-1/2 inch Copper DWV Reducing Adapter Soil X Copper DWV

2 inch x 1-1/2 inch Copper DWV Reducing Adapter – Soil x Copper DWV

The 2 inch x 1-1/2 inch Copper DWV Reducing Adapter is designed for transitioning between copper soil pipe and smaller copper DWV piping in drain, waste, and vent systems. Constructed from durable, corrosion-resistant copper, this fitting ensures a secure, code-compliant connection for gravity-flow applications.

Performance and Design Highlights

• ✅ Material: Wrought copper conforming to ASTM B75 or B88 standards
• ✅ Type: Reducing adapter with a large-end soil pipe cup and small-end copper DWV connection
• ✅ Connection: Bell x Cup (Soil x Copper) – designed for soldering or brazing
• ✅ Application: DWV systems operating under atmospheric pressure
• ✅ Compliance: Meets ASME B16.29 for DWV copper fittings

Installation Notes

Installation involves joining the large end to a 2 inch copper soil pipe and the reducing end to a 1-1/2 inch copper DWV line. Use lead-free solder and follow local plumbing codes for preparation, alignment, and heat application. Ensure piping is properly cleaned and fluxed to maintain joint integrity. This adapter is not rated for pressurized systems and should only be used in non-pressurized DWV applications.

Use Cases

• Multi-story residential drainage stacks requiring size transitions
• Vent line modifications where pipe diameter changes are necessary
• Basement or crawl space piping reductions in remodels and repipes

Benefits for Professional Installations

• ✅ Dimensional Accuracy: Precision-machined ends simplify alignment and improve solder coverage
• ✅ Long Service Life: Copper’s corrosion resistance makes it ideal for DWV applications in harsh environments
• ✅ Thermal Compatibility: Compatible with standard copper pipe thermal expansion and contraction behavior

Additional Information

This reducing adapter is lead-free and supports compliance with national plumbing codes requiring the use of safe materials in residential and commercial drainage applications. It offers a reliable solution when transitioning between pipe diameters without compromising system flow dynamics or structural integrity.

Designed for performance in non-pressurized systems, the 2 inch x 1-1/2 inch Copper DWV Reducing Adapter is an essential component for any contractor working in copper DWV installations where dimensional transitions are required.
