90-Degree Closet Elbow Design
The 90-degree closet elbow redirects compatible PVC DWV piping through a right-angle turn while accommodating the connection arrangement required for a closet drainage installation.
Confirm the required elbow orientation before installation so the fitting aligns correctly with the adjoining piping and planned drainage route.
3" x 4" Reducing Configuration
The 3" x 4" configuration combines two different nominal connection sizes within the same fitting. This allows the closet elbow to provide both a 90-degree directional change and a size transition without requiring separate reducing and elbow fittings.
Verify the required 3" and 4" connection positions before assembly to ensure the reducing configuration matches the planned DWV layout.
Spigot x Hub Connections
The street-style S x H configuration incorporates a spigot connection on one end and a hub connection on the other. The spigot end is designed to fit into a compatible PVC hub, while the hub end receives compatible PVC DWV pipe or a properly sized spigot connection.
This arrangement can provide a compact fitting-to-fitting connection while maintaining the required 3" x 4" size transition within the closet drainage system.
PVC DWV Closet Applications
This reducing closet elbow is intended for compatible PVC drain, waste, and vent piping requiring a 90-degree turn, 3" x 4" size transition, and street-style connection arrangement.
Before installation, verify both nominal sizes, S x H configuration, fitting orientation, adjoining piping, available clearance, and compatibility with the overall closet drainage layout.
Installation & Selection Considerations
- Confirm the 3" x 4" size.
- Verify the 90-degree angle.
- Confirm the S x H design.
- Use proper PVC solvent-welding procedures.
- Verify orientation with the planned closet drainage layout.

Our PVC DWV fitting specialists can help review your 3" and 4" connection requirements, 90-degree reducing closet elbow configuration, S x H connections, fitting orientation, installation clearance, adjoining piping, and overall closet drainage layout before you order.
