Zoeller 12094 4 Inch Inlet Hub Simplex Basin

Product Description

The ZOELLER 12094 is a 4-inch inlet hub designed for use with simplex basin assemblies. It provides a secure, properly sized entry point for incoming drain or waste lines into the basin, maintaining a watertight connection at the basin wall. This fitting is a component-level part typically installed by licensed plumbers during new basin assembly or basin replacement work. It is sized to accept 4-inch inlet piping and is built to ZOELLER specifications for reliable service in residential and light-commercial pump basin applications.

This inlet hub is used in simplex basin configurations where a single pump system is installed to handle sewage, effluent, or stormwater. It is intended for use with ZOELLER basin systems in the 31-1099 series, making it a direct-fit component for those assemblies.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off all connected pump systems and relieve any pressure in the line before beginning work on the basin. Ensure the hub is fully seated and sealed at the basin wall before making pipe connections.
