Reduced Wye, Socket PVC Schedule 40 2" x 1/2" (475-247)

The 475-247 is a PVC Schedule 40 reduced wye fitting with a 2" socket run and a 1/2" 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 pressure loss and solids accumulation risk 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 stepping down to a 1/2" branch — is the most extreme size reduction available in the 2" reduced wye series, allowing the smallest standard pipe size to tie into a 2" mainline with virtually no impact on mainline flow capacity at the junction.

The 1/2" branch of the 475-247 serves the most specialized application in the 2" reduced wye family: the tie-in of absolute minimum-flow discharge points — individual condensate taps, pressure relief valve discharge lines, air vent connections, equipment drain ports, and overflow outlets — into a 2" gravity drain collection main. At a 2" to 1/2" reduction, the branch is a nominal tributary by any measure; the mainline carries all meaningful flow volume while the branch introduces only intermittent or minimal discharge into the drain run. This makes the 475-247 the correct fitting when no other SKU in the 475-24x series is appropriately sized for the branch — completing the full range below the 475-248 (3/4"), 475-249 (1"), 475-250 (1-1/4"), and 475-251 (1-1/2") and providing the final step-down option for designers and contractors who need to consolidate a 1/2" discharge point into an existing 2" drain main without installing a separate stub-out fitting or reducing bushing at the branch. 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 throughout residential and commercial drain rough-in.

Industries & Applications:

• Drain, Waste & Vent (DWV) — Connecting 1/2" pressure relief valve discharge lines, equipment overflow outlets, air vent connections, and minimal-flow drain taps to 2" sanitary waste consolidation runs and drain stacks with smooth, flow-aligned wye geometry that preserves full mainline drainage capacity
• HVAC & Mechanical — Tying 1/2" condensate drain taps, air handler overflow connections, and equipment drain ports into 2" primary condensate collection mains in residential and commercial mechanical installations where the branch carries only intermittent or minimal discharge volume
• Commercial Plumbing — Consolidating 1/2" equipment overflow lines, relief valve discharge points, and utility drain taps into 2" primary waste runs in mechanical rooms, equipment areas, and utility corridors where multiple minor discharge points must join a common collection main
• Residential Construction — Drain rough-in where 1/2" pressure relief, overflow, or appliance discharge lines connect to 2" main drain runs in utility spaces, mechanical closets, and water heater installation areas
• Industrial Drainage — Minimal-flow branch connections in gravity-flow industrial drain systems where 1/2" equipment drain ports and low-volume process discharge taps join 2" collection mains with negligible impact on mainline drainage flow
• Water Treatment & Mechanical Systems — Sample ports, chemical feed discharge points, and low-volume drain taps off 2" gravity collection mains in water treatment, filtration, and mechanical system drain manifolds
