The COPPERFIT 1A1710 is a 4-inch ABS DWV sanitary tee designed for drain, waste, and vent piping systems in residential and light commercial plumbing. Made from acrylonitrile butadiene styrene (ABS) material, this fitting provides a swept branch inlet that directs waste flow smoothly in the direction of drainage, reducing the risk of clogs and turbulence at the junction. At 1.95 pounds, the fitting is lightweight enough for single-person handling during installation. Licensed plumbers and qualified pipefitters install this type of fitting as part of the below-slab, in-wall, or above-ceiling DWV rough-in.
The 1A1710 sanitary tee is suited for 4-inch ABS DWV piping systems in residential construction and light commercial applications. Common install locations include main stack connections, horizontal branch connections to a vertical stack, and closet flange rough-ins where a branch tie-in is required. The swept design of the tee is code-appropriate for use in drain and waste lines. It is not intended for use in pressure piping systems.
Designed as an OEM-style replacement and new-construction fitting for 4-inch ABS DWV piping systems in residential and light commercial drain, waste, and vent applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing code. Shut off the water supply and ensure the existing drain line is cleared before cutting into an active system. Use the appropriate ABS solvent cement and primer as required by local code; allow full cure time before restoring flow. The sanitary tee must be oriented so the swept branch flows in the direction of drainage — never install this fitting with the branch opposing flow direction in a drain or waste line.
