1-1/2 inch Copper DWV 90° Elbow – For Directional Flow in Drainage Systems

The 1-1/2 inch Copper DWV 90° Elbow is a long-radius quarter bend designed for use in drain, waste, and vent piping systems. It facilitates directional changes in horizontal or vertical DWV lines while maintaining consistent flow characteristics required by plumbing codes. This fitting is precision-formed to ensure consistent wall thickness, clean bends, and reliable soldering surfaces.

Fabricated from wrought copper, this elbow meets ASTM B75 and ASME B16.29 specifications, ensuring it complies with industry requirements for DWV copper systems. It is intended for use in non-pressurized systems and is lead-free in accordance with national regulations. The smooth interior and resistance to corrosion make it a durable solution in sanitary drainage applications.

Where It's Used

This elbow is used to change the direction of flow in horizontal or vertical DWV copper lines, particularly behind walls, beneath floors, or in overhead installations. It is commonly installed in residential, multi-family, and light commercial buildings where copper is specified for drain infrastructure.

Installation Guidelines

Install using conventional soldering practices with compatible flux and solder. Clean and deburr the tubing ends before assembly. Apply appropriate flux to the joint area, insert the tube fully into the socket, and heat evenly until the solder flows to fill the cup. Overheating should be avoided to prevent weakening the fitting or pipe.

Did You Know?

Copper DWV fittings are often used in acoustically sensitive installations because copper's density helps reduce sound transmission from draining water—an important consideration in multi-unit or commercial environments.

For code-compliant and reliable directional changes in DWV systems, the 1-1/2 inch Copper 90° Elbow provides the performance and durability professionals require. It’s a trusted component for achieving clean, long-lasting drainage system layouts in copper-based designs.
