PVC Wye Trap for 4-Inch Drain Lines

This Mueller Industries PVC wye trap connects three sections of 4-inch Schedule 40 pipe in a drainage system. The white fitting uses solvent-weld hub sockets on all three ends for permanent, leak-resistant joints. It is designed for gravity-flow waste and vent installations in residential and light-commercial plumbing.

Schedule 40 Capacity and Pressure Limits

The fitting handles gravity-flow drainage at atmospheric pressure and operates between -20 and 140 degrees Fahrenheit. It is not rated for pressurised supply lines or high-temperature discharge above the stated maximum. The three 4-inch hub sockets accept standard Schedule 40 pipe with a 4-1/2 inch outside diameter.

Three-Way Hub Configuration Decides Fit

All three connections are female socket ends sized for 4-inch Schedule 40 pipe, requiring solvent cement for assembly. The overall length is 8-1/16 inches. Installers needing a different pipe diameter, a threaded connection, or a cleanout access must choose another fitting.

Questions about this item

Will this 4 in PVC wye trap connect directly to my existing Schedule 40 pipe?

Yes, the hub sockets are sized for 4 in Schedule 40 pipe with a 4 1/2 in outside diameter and use a solvent-weld joint.

How can I confirm the trap is flowing correctly after installation?

Run water through the system and verify gravity flow at all three hub connections without leaks at the socket joints.

Does the 1WJU5 come with solvent cement or seals, or must I buy them separately?

The fitting is supplied without seal or cement; you will need to purchase PVC solvent cement and primer separately for the socket connections.
