Zoro Select Reducing Wye 221722

The Zoro Select 221722 is a reducing wye that combines a wye branch with a 1/8 bend for 4 x 6 pipe connections. It suits plumbers and contractors routing drainage or vent lines where a directional change and branch join are required in one fitting. The component is supplied new and ready for installation in compatible piping systems.

Behaviour under sustained flow

The fitting maintains a continuous internal path that resists debris build-up during long-term drainage service. Its combined wye and bend geometry keeps flow velocity steady without the turbulence that separate elbows and tees can create. The moulded construction eliminates joint gaps that could leak under constant hydraulic pressure.

Upgrade from separate fittings

This single casting replaces an assembly of a reducing wye plus a separate 1/8 bend, cutting solvent-weld joints and alignment time. The reduction is worthwhile when space is tight or when fewer potential leak points are specified. Installers needing a straight reducing wye without the integral bend should select a different fitting.

Highlights

  • Reduces pipe diameter from 6 to 4 inches
  • Combination wye merges wye and 1/8 bend functions
  • Single fitting replaces two separate components
  • Simplifies drainage layout with integrated design
  • New condition ensures reliable installation performance

Questions about this item

How much heat does the 221722 reducing wye generate when waste water runs through it all day?

The fitting is a passive PVC component with no moving parts or electrical supply, so it produces no measurable heat during continuous drainage flow.

What existing pipe sizes must I already have to connect the 4 x 6 reducing wye?

You need a 6-inch main line and a 4-inch branch line, both compatible with standard DWV solvent-weld or gasket joints.

Will the 221722 wye fit alongside older cast-iron or ABS drain lines I am keeping?

Yes, the hub dimensions follow standard DWV sizing, so it can be joined to legacy cast-iron or ABS using appropriate transition couplings.
