The COPPERFIT 1A1825 is a 1.5-inch ABS DWV 45-degree wye fitting used in drain, waste, and vent piping systems. It allows a branch line to tie into a main drain line at a 45-degree angle, supporting proper flow direction and reducing turbulence in the line. Weighing 0.29 pounds, this lightweight fitting is straightforward to handle and cut to fit during rough-in work. Plumbers and pipefitters install this type of fitting in both new construction and remodel projects where code-compliant DWV layout is required.
This fitting is suited for residential and light commercial drain, waste, and vent applications where 1.5-inch ABS pipe is specified. Common installation scenarios include branch connections at lavatory drains, washing machine standpipes, and similar low-flow fixture tie-ins. ABS DWV systems are commonly found in residential construction, particularly in regions where ABS is the code-accepted material for drain and vent piping.
Designed as an OEM-style replacement and new-installation fitting for 1.5-inch ABS DWV piping systems in residential and light commercial drain, waste, and vent applications.
Installation is performed by a licensed plumber or qualified pipefitter in accordance with local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off any upstream flow and ensure the pipe is dry before cementing. Cut pipe square, deburr all edges, and apply ABS solvent cement to both the pipe end and the fitting socket per the cement manufacturer's instructions. Do not pressure-test ABS DWV assemblies beyond the rated non-pressure service limits for the fitting.
