Reduced Wye, Socket PVC Schedule 40 2" x 1" (475-249)

The 475-249 is a PVC Schedule 40 reduced wye fitting with a 2" socket run and a 1" socket branch outlet, all joined by solvent cement welding per ASTM D2564. The wye configuration positions the branch at a 45-degree angled takeoff from the mainline rather than the perpendicular 90-degree branch of a standard tee, producing a smoother, lower-turbulence flow transition at the branch junction that reduces flow restriction and minimizes the pressure loss and solids accumulation risk associated with abrupt directional changes at the branch point.

Manufactured from rigid PVC compound conforming to ASTM D1784 cell classification requirements, this fitting delivers the corrosion resistance, chemical compatibility, and long service life associated with Schedule 40 PVC across a wide range of drainage, waste, vent, and low-pressure distribution applications. The reduced configuration — 2" run reducing to a 1" branch — allows a smaller-diameter lateral or drain line to tie into a larger-diameter mainline at the branch, a layout common in DWV systems where individual fixture or appliance drain lines at 1" consolidate into a 2" primary drain run or waste collection main.

The 1" branch size of the 475-249 serves a specific application within the 2" reduced wye series: the tie-in of the smallest standard drain branch size into a 2" consolidation main. At 1", the branch accommodates individual appliance drain lines, condensate discharge lines, small floor drains, and other low-volume fixture connections that feed into a larger 2" waste run. The two-step reduction from run to branch — larger than the one-step reductions of the 475-250 (1-1/4") and 475-251 (1-1/2") — means this fitting is appropriate where the branch flow volume is modest relative to the mainline and where keeping the consolidation drain at full 2" capacity is a priority. The wye's angled branch geometry follows the natural direction of drainage flow, reducing the likelihood of solids and debris accumulation at the junction compared to a sharp tee branch and making the 475-249 the preferred fitting for long-term, low-maintenance gravity drain installations. Where a direction change is also needed at the branch connection, pairing this wye with a 45-degree elbow produces the standard DWV sweep configuration used in residential and commercial drain rough-in.

Industries & Applications:

• Drain, Waste & Vent (DWV) — Connecting 1" appliance drain lines, condensate discharge pipes, small floor drains, and low-volume fixture connections to 2" sanitary waste consolidation runs and drain stacks with smooth, flow-aligned branch geometry
• Commercial Plumbing — Waste line consolidation in commercial buildings where 1" appliance, equipment, or utility drain branches tie into 2" primary waste runs during rough-in, particularly in mechanical rooms and utility areas with multiple low-flow drain sources
• Residential Construction — Drain and waste rough-in where 1" appliance drain lines — washing machines, HVAC condensate, water softener discharge — connect to 2" main drain runs in walls, floors, and utility spaces
• HVAC & Mechanical — Consolidating 1" condensate drain lines from air handlers, fan coils, and cooling equipment into 2" primary condensate collection mains in commercial mechanical rooms and multi-unit HVAC installations
• Industrial Drainage — Low-turbulence branch connections in gravity-flow industrial drain systems where 1" equipment drain lines tie into larger 2" collection mains handling process water and equipment washdown effluent
• Municipal & Site Drainage — Branch connections in site sanitary sewer lateral manifolds and gravity-flow collection systems where small-diameter 1" laterals tie into 2" consolidation mains with clean, flow-aligned transitions
