Product Purpose

The Mueller Industries 05845 is a PVC DWV double reducing wye designed for gravity-flow drainage systems. It connects four socket hubs in a 4x4x2x2 configuration to join multiple branch lines into a main stack.

Thermal And Pressure Limits

The fitting is rated for gravity flow maximum operating pressure and handles continuous fluid temperatures from minus 20 degrees up to 140 degrees Fahrenheit. Schedule 40 PVC construction provides chemical resistance for standard waste applications.

Sustained Load Behaviour

Under constant drainage flow the socket joints maintain alignment without mechanical fasteners or included seals. The rigid PVC body resists deformation at the upper temperature limit and does not require periodic retightening during long-term service.

  • Connects four pipe sizes in one fitting
  • Schedule 40 PVC handles 140 Degrees F continuous flow
  • White finish matches standard DWV installations
  • Socket ends install without threading tools

Questions about this item

How do I solvent-weld the 4-inch and 2-inch hub sockets on this Schedule 40 PVC double reducing wye?

Dry-fit all four sockets, prime and cement each joint, fully seat pipes with a quarter-turn, and hold until the bond sets; the step most often missed is skipping primer on the 2-inch sockets.

What maintenance will the Mueller 05845 need after installation?

No routine maintenance is required; only clear blockages through clean-outs and replace the fitting if cracking or joint leakage appears.

At what temperature does this PVC wye reach its maximum continuous operating limit?

140 degrees Fahrenheit is the highest sustained temperature rated for gravity-flow service.
