The ABI FOUNDRY 1584 is a 3-inch service weight cast iron wye fitting used in drain, waste, and vent (DWV) piping systems. It features a spigot x hub x hub end configuration, allowing it to connect into existing cast iron drain lines where one end slides into a hub and the branch and run outlets accept hub-style connections. This domestic-manufactured fitting is rated for temperatures from 32 degrees F to 212 degrees F, making it suitable for standard residential and commercial drainage applications. Licensed plumbers and pipefitters install this type of fitting during rough-in or repair work on cast iron DWV systems.
This wye is used in residential and light commercial drain, waste, and vent piping where a branch connection is required at an angle along a horizontal or vertical run. The 3-inch nominal size is a common dimension for branch lines serving lavatories, floor drains, and secondary drain stacks. The spigot x hub x hub configuration is typical for transitioning from a cut section of existing service weight cast iron pipe into a new branch tee arrangement. This fitting is manufactured domestically and is appropriate for new construction, renovation, and repair work in cast iron DWV systems.
Designed as an OEM-style replacement or new-installation fitting for 3-inch service weight cast iron DWV piping systems using spigot and hub connections.
Installation of cast iron DWV fittings is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Shut off water service and ensure the drain line is clear and depressurized before cutting into existing pipe. Lead and oakum joints or no-hub couplings may be used depending on the connection method required at the spigot end. Support the fitting and adjacent pipe per code-required hanger spacing for cast iron pipe.
