Copperfit 1A1840 Abs Dwv 45 Degree Wye 4x3 in

Product Description

The COPPERFIT 1A1840 is an ABS DWV 45-degree wye fitting sized at 4 inches by 3 inches, designed for use in drain, waste, and vent piping systems. This fitting 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 drain stack. Constructed from ABS (acrylonitrile butadiene styrene) material, it offers durability and resistance to common household drain chemicals. It is installed by licensed plumbers and experienced pipefitters working on residential and light commercial DWV systems.

This wye fitting is used in below-grade and above-grade DWV installations where a 4-inch main line requires a 3-inch branch connection at a 45-degree angle. Typical applications include toilet drain tie-ins, main stack branches, and horizontal drain runs requiring a swept branch outlet. The 45-degree angle promotes self-scouring flow and is favored over 90-degree fittings in many horizontal drain configurations per standard plumbing codes.

Key Features

• 45-degree sweep angle supports proper DWV flow and reduces clogs
• 4 x 3 inch reducing configuration connects main and branch lines of different sizes
• ABS construction provides chemical resistance and long service life
• Suitable for both horizontal and vertical DWV piping runs
• Lightweight design simplifies handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial ABS DWV piping systems using 4-inch main lines with 3-inch branch outlets.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Solvent-weld the fitting using ABS-rated cement and primer, following manufacturer and code requirements for joint cure time before pressure testing. Ensure all drain lines maintain the required slope per code before securing the fitting in place. Do not use PVC solvent cement on ABS fittings.
