Mueller Streamline DWV90LLT112 Wrot Copper 90 Elbow 1.5in

Product Description

The MUELLER STREAMLINE DWV90LLT112 is a wrot copper long radius 90 degree elbow designed for drain, waste, and vent (DWV) piping systems. Sized at 1.5 inches x 1.5 inches, this fitting redirects flow at a full 90 degree angle using a long radius sweep, which reduces turbulence and supports proper drainage velocity in gravity-flow systems. Wrot copper construction means the fitting is formed from wrought copper, delivering consistent wall thickness and reliable soldered joints. Licensed plumbers and pipefitters install this fitting in residential and light commercial DWV applications.

This elbow is used in DWV drain lines, vent stacks, and waste piping where a 90 degree directional change is required. The long radius design is preferred over short radius elbows in horizontal drain runs and where smooth flow transition is a priority. Typical installations include bathroom drain assemblies, kitchen sink waste lines, and branch vent connections. The 1.5 inch size is a common dimension for lavatory and sink drain service.

Key Features

• Long radius sweep reduces flow restriction and supports self-scouring drainage velocity
• Wrot copper construction provides uniform wall thickness for consistent solder joint quality
• 90 degree turn suited for DWV drain, waste, and vent piping configurations
• 1.5 inches x 1.5 inches sizing matches standard lavatory and sink drain line dimensions
• Compatible with standard sweat (solder) joining methods per common plumbing codes

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1.5 inch copper DWV piping systems joined by sweat soldering in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off the water supply and ensure the drain line is clear and dry before cutting into existing pipe. Use appropriate flux and lead-free solder when making sweat connections on potable or DWV copper systems. Support piping per code-required hanger spacing to prevent stress on soldered joints.
