Mueller Industries, Inc. 05843 PVC Double Reducing Wye Trap

SKU CH-B3X9-BMBRZ MPN 05843

Connects four pipes in a double reducing wye configuration for gravity drainage systems

  • TypeDrain Components
  • Connects four pipe sizes with a single PVC fitting
  • Schedule 40 construction handles gravity-flow drainage reliably
  • Operates from -20 to 140 degrees Fahrenheit
  • Hub socket design simplifies solvent-weld installation
  • White PVC resists corrosion in plumbing systems

Product Purpose

The Mueller Industries 05843 is a PVC double reducing wye designed to join four pipe sections in a drainage system. It connects two 3-inch hubs and two 1-1/2-inch hubs using solvent-weld sockets for gravity-flow applications.

Suitable Installations

This fitting suits plumbers assembling Schedule 40 DWV networks where a single junction must step down from 3-inch to 1-1/2-inch branches. Installers needing a straight coupling, a single wye, or a fitting rated for pressure service should select a different component.

Critical Specification

The fitting carries a maximum operating pressure rating for gravity flow only and an operating temperature range of -20 degrees to 140 degrees F. Systems that require pressure containment or exposure beyond this range cannot use this part.

Highlights

  • Connects four pipe sizes with a single PVC fitting
  • Schedule 40 construction handles gravity-flow drainage reliably
  • Operates from -20 to 140 degrees Fahrenheit
  • Hub socket design simplifies solvent-weld installation
  • White PVC resists corrosion in plumbing systems

Questions about this item

What comes in the box with the Mueller 05843 PVC double reducing wye?

The fitting itself is supplied; solvent cement and primer for the socket joints are not included and must be purchased separately.

How do I choose the right schedule for this 3 in by 1-1/2 in reducing wye?

This model is Schedule 40 throughout; select it when your drainage system uses Schedule 40 pipe and fittings.

What does the 140 °F maximum operating temperature mean for a gravity-flow installation?

The fitting is rated for continuous use up to 140 °F in non-pressurised gravity drainage, so hot-water discharge lines must stay below that limit.
