Mueller Streamline DWV90L112 90 Degree Elbow 1-1/2 in

Product Description

The MUELLER STREAMLINE DWV90L112 is a wrot copper 90-degree elbow designed for drain, waste, and vent (DWV) piping systems. Sized at 1-1/2 inches with a cup-by-cup (C x C) end connection, it joins two sections of copper DWV pipe at a right angle. Wrot copper construction provides consistent wall thickness and a smooth interior bore, which supports proper drainage flow and reliable solder joints. Licensed plumbers install this fitting during rough-in work on residential and light commercial drain lines.

This elbow is used in DWV applications where a 90-degree change of direction is required in a horizontal or vertical drain or vent stack. The C x C socket ends accept standard 1-1/2 inch copper pipe and are soldered using standard lead-free plumbing solder per applicable code requirements. Typical installations include sink drains, lavatory vents, and branch drain connections within walls or ceiling cavities.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing codes. Shut off the water supply and drain the affected lines before cutting into existing pipe. Clean and flux all mating surfaces before soldering, and use only lead-free solder where required by code. Do not apply mechanical stress to the joint until the solder has fully cooled and set.
