Wye, Slip PVC Schedule 40 3" (475-030)
$27.91
The 475-030 is a 3" Schedule 40 PVC Wye with Slip socket connections. This fitting introduces a branch into a drain, waste, or vent (DWV) line at a 45° angle — the defining geometry of the wye configuration — allowing flow from a lateral branch to enter the main line in the direction of flow rather than against it. This angled entry produces significantly less turbulence and flow resistance than a tee fitting, making the wye the preferred branch fitting in drain and waste systems where smooth, unobstructed flow and resistance to solids buildup are the governing design considerations.
All three sockets accept solvent cement for permanent, bonded connections to standard 3" Schedule 40 PVC pipe. The two inline sockets form the main run of the drain line, while the 45°-angled branch socket receives the lateral connection. The branch angle ensures that waste entering from the lateral is directed downstream in the flow direction of the main line immediately upon entry, minimizing the standing water, turbulence, and potential for blockage that a perpendicular tee branch would introduce in a gravity-flow system.
⚠️ Important — DWV Application Note: The 475 series wye is a drain, waste, and vent (DWV) fitting, not a pressure fitting. Schedule 40 PVC wyes in this series are manufactured and rated for gravity-flow drain systems — they are not pressure-rated for use in pressurized supply or distribution piping. Confirm that this fitting is appropriate for your application before specifying. For pressure systems requiring a branch at a similar angle, a Schedule 40 or Schedule 80 lateral or pressure-rated wye is the correct specification.
At 3", the 475-030 is sized for commercial and light industrial drain applications — building sanitary drain lines, floor drain branch connections, industrial waste drainage, and large-diameter vent stack assemblies — where 3" is a commonly specified main line or branch diameter. The white Schedule 40 PVC compound is lightweight, easy to handle and cut in the field, chemically resistant to the broad range of drain and waste fluids encountered in commercial and industrial installations, and fully compatible with standard PVC DWV solvent cement systems.

⚠️ Note: This is a DWV fitting — do not use in pressurized pipe systems. Always primer before cementing PVC DWV joints at 3". Ensure correct orientation during installation — the branch socket must be aligned in the direction of downstream flow before the joint sets.
Industries & Applications:
- Commercial Plumbing & Building Drain Systems — Branches 3" sanitary drain laterals into main building drain lines at a flow-friendly 45° angle, reducing blockage risk and improving drain performance in multi-fixture commercial plumbing systems
- Industrial Waste Drainage — Used in industrial facility floor drain collection systems, process waste lines, and wash-down drainage networks where 3" PVC DWV piping is specified for chemical resistance and low maintenance
- Institutional & Municipal Facilities — Specified in large commercial buildings, schools, hospitals, and municipal facilities on sanitary drain trunk lines where a wye is preferred over a tee for its superior flow characteristics in high-use drain systems
- Light Manufacturing & Food Processing — Routes waste water and process drainage from production areas into main collection lines, with the wye geometry reducing the risk of solids accumulation at the branch point in systems carrying particulate-laden waste streams
- Vent Stack Assemblies — Used in DWV vent piping configurations where a 45° branch connection into a vent stack or vent main is required to maintain proper venting geometry per plumbing code
- Retrofit & Renovation Plumbing — Commonly used when adding a new drain branch to an existing 3" PVC drain line, with the wye's 45° geometry simplifying the tie-in and maintaining drainage slope continuity in the modified line

Wye, Slip PVC Schedule 40 3" (475-030)
Technical Specifications
The 3" Wye, Slip PVC SCH 40 (Part #475-030) is engineered for dependable performance across residential, commercial, and industrial plumbing systems. With a three-inch nominal size, this fitting features Socket × Socket × Socket slip connections for secure, solvent-weld installation. Made from durable Schedule 40 PVC, the fitting is lightweight, corrosion-resistant, and ideal for gravity flow or low-pressure liquid applications.
This white PVC wye meets ASTM D1784 material standards, rated for a maximum service temperature of 140°F. Contractors benefit from packaging options ranging from a carton quantity of five to a pallet quantity of 200, making it suitable for everything from small repairs to large project builds.
Typical Applications
A 3" PVC wye is trusted wherever a system needs a smooth, efficient branch connection that can maintain consistent flow. Its angled design minimizes turbulence and reduces clogging risk in systems where debris or high-volume water movement is common.
Several industries and systems rely on this fitting, such as:
- DWV plumbing systems (drainage, waste, and vent)
- Agricultural irrigation networks and water distribution lines
- Pool and spa plumbing for balanced flow direction
- Aquaculture and fish-farm systems requiring steady circulation
- Light commercial and industrial piping where angled routing improves system efficiency
- Stormwater management and runoff control systems
The flow-optimized wye branch makes this fitting especially beneficial in settings that prioritize preventing blockages and maintaining velocity.
Installation & Handling Tips
For the best results, follow the steps below to properly prepare the pipe and fitting before installation:
- Clean all slip ends and sockets to remove dirt, moisture, or debris.
- Apply PVC primer, followed by solvent cement, to each connection according to the manufacturer’s instructions.
- Orient the wye correctly, confirming that the branch angle supports natural flow direction in drainage or irrigation systems.
- Insert the pipe fully and hold briefly to prevent push-out during initial set.
- Support the piping system, especially around the branch, to avoid stress that can weaken joints.
- Allow proper curing time before pressure testing or operation.
- Avoid over-tightening straps or clamps that may place unnecessary pressure on the fitting.
