The COPPERFIT 1A1826 is a 2-inch ABS DWV 45-degree wye fitting designed for drain, waste, and vent piping systems. This fitting provides a 45-degree lateral branch connection in ABS plastic pipe runs, allowing plumbers to route waste lines cleanly within residential and light commercial drainage systems. The wye configuration reduces turbulence and supports proper drainage flow compared to sharp-turn fittings. At 0.43 pounds, it is lightweight and easy to handle during overhead or in-wall rough-in work.
This fitting is used in below-slab, in-wall, and overhead DWV installations where a branch takeoff at 45 degrees is required. Typical applications include toilet drain branches, sink waste connections, and vent stack laterals in residential new construction and remodel projects. It is installed by licensed plumbers and trained pipe fitters working with ABS plastic drain piping.
Designed as an OEM-style replacement or new-installation fitting for 2-inch ABS DWV piping systems in residential and light commercial drain, waste, and vent applications.
Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off water supply and ensure the drain system is empty and dry before cutting into an existing line. Solvent-cement both the fitting socket and pipe end per the ABS cement manufacturer instructions, and allow adequate cure time before restoring service. Do not use PVC solvent cement on ABS fittings.
