Nibco e090000 Cast Copper Dwv 45 Wye 1-1/4 in

Product Description

The NIBCO e090000 is a 1-1/4 inch cast copper sweat DWV 45-degree wye fitting used in drain, waste, and vent piping systems. It is designed to join a branch line at a 45-degree angle to a main drainage run, allowing for smooth, low-turbulence flow transitions. The fitting is manufactured from cast copper and is joined using standard sweat (solder) connections on all three ports. Plumbers install this fitting in residential and light commercial DWV applications where copper piping is specified.

This wye fitting is suited for horizontal drain runs and stack installations where a 45-degree branch takeoff is required. The 1-1/4 inch size is commonly used for lavatory drains, indirect waste lines, and branch connections within a larger DWV system. Installation follows IPC and local plumbing code requirements for copper DWV piping.

Key Features

• Cast copper construction for durability in drain, waste, and vent service
• 45-degree wye configuration promotes smooth drainage flow and reduces buildup
• Sweat (solder) end connections on all ports for a leak-tight joint
• 1-1/4 inch port size fits standard copper DWV tubing
• Compatible with lead-free solder for potable-adjacent installations

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-1/4 inch copper DWV piping systems installed per IPC and local plumbing codes.

Installation Notes

This fitting is installed by licensed plumbers using a torch, flux, and lead-free solder in accordance with applicable plumbing codes. Shut off the water supply and drain the lines completely before cutting into an existing system. Clean all mating surfaces with emery cloth and apply flux evenly before soldering. Allow joints to cool fully before restoring flow or pressure-testing the line.
