PVC Wye 45 Degree Elbow

The Mueller Industries 1WJW8 is a white PVC drain fitting that combines a wye branch with a 45 degree elbow. It is designed for non‑pressure drainage systems in residential or light commercial plumbing. The hub connection accepts 3 inch schedule 40 pipe for a solvent‑weld joint. This fitting suits installers building or repairing DWV layouts.

Schedule 40 Hub Connection

The single specification that decides fit is the schedule 40 hub sized for 3 inch pipe. It meets ASTM D1784 cell class 12454 material requirements. The fitting is not rated for pressure applications and must only be used in gravity‑flow drain, waste and vent systems. Solvent cement creates a permanent, leak‑free joint.

140 Degree Temperature Limit

The PVC material handles continuous temperatures up to 140 degrees F, covering typical residential hot‑water discharge. It provides ample capacity for standard fixture drainage and venting. The fitting runs out where pressurised lines or higher‑temperature industrial waste are present, as it carries no pressure rating.

Questions about this item

How does the 45-degree angle affect flow in a real drainage system?

The 45-degree sweep provides a gradual directional change that maintains flow velocity and reduces turbulence compared to sharper bends, helping prevent solids from settling in the fitting.

What does the Schedule 40 rating mean for pressure handling in practice?

Schedule 40 defines the wall thickness for this 3-inch PVC fitting; it is not rated for pressure applications and is intended for gravity-flow drain, waste and vent systems only.

What does the hub connection require for a watertight joint?

The hub socket accepts 3-inch Schedule 40 PVC pipe and requires solvent cement applied to both the pipe exterior and socket interior to create a permanent, leak-free bond.
