The COPPERFIT 1A1709 is a 3-inch ABS DWV sanitary tee designed for drain, waste, and vent piping systems in residential and light commercial plumbing installations. Molded from acrylonitrile butadiene styrene (ABS), this fitting provides a smooth-flow branch connection that directs waste flow in a single direction, reducing the risk of backflow within the drain stack. At 1.01 pounds, it is lightweight enough for overhead and wall-cavity installations. Licensed plumbers and journeyman pipefitters install this fitting as part of rough-in drain systems governed by the International Plumbing Code (IPC) and local amendments.
This sanitary tee is suited for 3-inch ABS DWV pipe runs in new construction and remodel applications. Typical uses include branch connections off a main drain stack, wet-vent configurations, and horizontal-to-vertical waste transitions. It is appropriate for residential bathrooms, utility rooms, and light commercial restroom rough-in work where ABS piping is the specified or code-allowed material.
Designed as an OEM-style replacement and new-installation fitting for 3-inch ABS DWV piping systems where solvent-weld sanitary tee connections are required.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing code. Solvent-cement all joints using ABS-approved cement and primer per the pipe and cement manufacturer instructions. Ensure the sanitary tee is oriented correctly so the swept inlet points in the direction of flow before cementing, as the joint cannot be adjusted after solvent-weld sets. Confirm all rough-in work passes a pressure or air test as required by the authority having jurisdiction before closing walls or ceilings.
