PVC Sanitary Tee for Drain Systems

This Mueller Industries 1WJN9 is a white PVC double sanitary reducing tee designed for residential and commercial drain, waste and vent installations. It connects four hub sockets in a 4 in by 4 in by 2 in by 2 in configuration for gravity-flow plumbing.

Schedule 40 Pressure and Temperature Limits

The fitting is rated for Schedule 40 pipe at gravity-flow maximum operating pressure and handles continuous service from -20 degrees to 140 degrees F. It is not intended for pressurised supply lines or temperatures above the stated range.

Replaces Damaged or Undersized Branch Tees

Use this tee when an existing branch connection has cracked, leaks at the joint or cannot accommodate the required 2 in branches off a 4 in main. The jump is worth it when the current fitting restricts flow or fails inspection.

Questions about this item

Which Mueller Industries 1WJN9 PVC sanitary tee size should I select for a four-inch main line with two-inch branches?

Choose the 4 in x 4 in x 2 in x 2 in hub configuration; it matches a four-inch main and two two-inch branches in a single fitting.

What does the Schedule 40 rating mean for daily drainage use?

Schedule 40 indicates standard wall thickness for gravity-flow drainage, handling typical household waste water without pressure.

How does the socket hub interface limit installation options?

Each hub is a female socket joint; pipes must be solvent-welded into the sockets, so the fitting cannot be threaded or mechanically coupled.
