Description
3" x 4" PVC DWV 90 Street Reducing Closet Elbow (S x H)
3" x 4" PVC DWV 90 Street Reducing Closet Elbow (S x H) provides a 90-degree directional transition within compatible PVC drain, waste, and vent piping at a closet or toilet drainage connection. The street configuration combines a spigot connection with a hub connection while incorporating a 3" x 4" reducing size arrangement.
The 3" x 4" S x H street reducing closet elbow configuration combines a right-angle directional change, different nominal sizes, and two connection interfaces within one PVC DWV fitting. Selection should account for both connection sizes, spigot and hub compatibility, adjoining components, elbow orientation, joining requirements, piping alignment, support, and available installation clearance.

Street Closet Elbow Design
The street closet elbow configuration provides a 90-degree directional change while incorporating a spigot connection on one end. This allows the fitting to connect directly into a compatible receiving hub while providing the specified closet drainage transition.
The elbow orientation should be established before permanent joining so both connections align with the intended fixture and piping layout. Planning the position helps coordinate adjoining components, nearby fittings, support, and available working clearance.
Spigot & Hub Connections
The spigot connection fits into an appropriately sized compatible receiving hub, while the hub connection receives compatible PVC DWV pipe. Because the fitting uses a 3" x 4" reducing arrangement, each connection should be matched carefully to the correct adjoining component.
The mating surfaces should be prepared using the appropriate PVC DWV joining procedure. Proper insertion, compatible joining materials, correct elbow orientation, and careful alignment help establish the connections without unnecessary stress on the fitting.
PVC DWV Integration
The PVC DWV construction allows the street reducing closet elbow to integrate into compatible drain, waste, and vent piping arrangements at toilet fixture locations. Matching the 3" x 4" connection sizes and S x H interfaces to the adjoining components helps maintain the intended drainage configuration.
Application suitability should be evaluated using the requirements of the complete DWV system. Adjoining materials, connection compatibility, fixture location, joining materials, piping support, and local installation requirements should all be considered during fitting selection.
90° Reducing Transition
A 3" x 4" PVC DWV 90 Street Reducing Closet Elbow combines a right-angle transition, size reduction, and street-style connection within one fitting. The S x H arrangement provides a compact connection between compatible adjoining components.
Installation planning should consider elbow orientation, spigot engagement, fixture alignment, adjoining pipe position, nearby fittings, available clearance, and piping support. Connected components should align naturally without forcing the fitting into position.
Installation & Selection Considerations
- Confirm the 3" x 4" sizes.
- Verify the S x H arrangement.
- Check PVC DWV compatibility.
- Confirm the required 90° orientation.
- Align adjoining components before assembly.

Our PVC fitting specialists can help review the 3" x 4" configuration, DWV requirements, S x H connections, adjoining PVC components, fixture layout, elbow orientation, joining requirements, piping alignment, and available installation clearance before you order.
