Wye, Slip PVC Schedule 40 3" (475-030)

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
