Mueller Streamline ABSCOMBY21122 Abs Dwv Combo Tee Wye

Product Description

The MUELLER STREAMLINE ABSCOMBY21122 is an ABS DWV long radius combination tee wye fitting used in drain, waste, and vent piping systems. It measures 2 inches by 1-1/2 inches by 2 inches and connects via hub-to-hub-to-hub joints. The long radius sweep reduces flow restriction and minimizes clogging risk in drain lines. This fitting is installed by licensed plumbers during new construction or remodel work on residential and light commercial DWV systems. The ABS plastic construction is lightweight, corrosion-resistant, and compatible with standard ABS solvent-weld installation procedures.

This combination tee wye is suited for residential and light commercial drain, waste, and vent applications. The long radius design allows for smoother transitions at branch connections, making it appropriate for horizontal drain runs where flow velocity and solids transport matter. Plumbers use this fitting where a branch line must tie into a main drain line while maintaining proper drainage slope and venting continuity. It is a common fitting in under-floor and in-wall DWV rough-in work.

Key Features

• Long radius sweep reduces flow turbulence and blockage risk in drain lines
• Hub x Hub x Hub connection accepts standard ABS pipe solvent-weld joints
• ABS plastic construction resists corrosion and is lightweight for overhead or in-wall installation
• Combination tee wye geometry allows branch tie-in on horizontal and vertical drain runs
• Sized 2 inches x 1-1/2 inches x 2 inches for common residential DWV branch configurations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for ABS DWV piping systems using solvent-weld hub connections in residential and light commercial drain, waste, and vent applications.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code or applicable local code. Shut off the water supply and ensure the drain line is empty and dry before cutting into an existing system. Clean and dry all mating surfaces, apply ABS solvent cement evenly, and allow full cure time before restoring flow. Do not use PVC solvent cement in place of ABS-rated cement.
