Description
PVC DWV 90 Degree Reducing Sanitary Tee (H x H x H)
PVC DWV 90 Degree Reducing Sanitary Tee (H x H x H) provides a 90-degree reduced branch connection for compatible PVC drain, waste, and vent piping systems. The reducing sanitary-tee configuration combines a straight-through run with a smaller branch connection for DWV layouts requiring different nominal pipe sizes.
The Hub x Hub x Hub (H x H x H) configuration provides three hub connections for compatible PVC pipe or properly sized spigot connections. Its reducing sanitary-tee design combines the branch transition and size reduction within a single fitting for a compact three-way DWV connection.

90-Degree Reducing Branch
The 90-degree reducing branch provides a perpendicular connection to the straight-through portion of the sanitary tee while accommodating a smaller nominal branch size. This allows different PVC DWV pipe sizes to be incorporated into the same three-way connection.
Confirm the main-run and reduced branch sizes before installation so each connection matches the planned drainage piping.
Reducing Sanitary Tee Configuration
The reducing sanitary tee design combines a straight-through DWV run and reduced branch connection within a single PVC fitting. This provides a compact transition where the planned system requires a smaller branch to connect to the larger main configuration.
Verify that the reducing sanitary tee configuration and branch orientation are appropriate for the intended DWV piping location before installation.
Hub x Hub x Hub Connections
The H x H x H configuration incorporates three hub connections. Each hub is designed to receive compatible PVC pipe or a properly sized spigot connection for solvent-weld assembly.
Confirm all three nominal connection sizes and properly prepare the compatible PVC mating surfaces before assembling the fitting into the DWV system.
PVC DWV Applications
This reducing sanitary tee is intended for compatible PVC drain, waste, and vent piping systems requiring a straight-through connection with a smaller 90-degree branch.
Before installation, verify the main-run sizes, reduced branch size, H x H x H configuration, branch direction, fitting orientation, available clearance, and compatibility with the adjoining PVC DWV piping.
Installation & Selection Considerations
- Confirm all fitting sizes.
- Verify the reduced branch size.
- Check the sanitary tee orientation.
- Confirm all three hub connections.
- Use proper PVC solvent-welding procedures.

Our PVC DWV fitting specialists can help review your main and reduced branch pipe sizes, 90-degree branch connection, H x H x H configuration, sanitary tee orientation, adjoining PVC piping, installation requirements, and overall DWV system layout before you order.
Frequently Asked Questions
What is a PVC DWV 90 Degree Reducing Sanitary Tee used for?
It provides a three-way PVC DWV connection with a 90-degree reduced branch connected to a straight-through main run.
What does H x H x H mean?
H x H x H means Hub x Hub x Hub. The reducing sanitary tee provides three hub connections.
What makes this a reducing sanitary tee?
The fitting incorporates different nominal connection sizes so a smaller branch can connect to the larger straight-through DWV configuration.
What is the branch angle?
The branch connection is positioned at 90 degrees to the straight-through portion of the sanitary tee.
What connects to the hub ends?
The hub connections are designed to receive compatible PVC pipe or properly sized spigot connections.
Why is fitting orientation important?
The fitting must be positioned so the straight run and reduced branch align correctly with the intended PVC DWV piping arrangement.
How are the PVC connections assembled?
Compatible PVC mating surfaces are prepared and joined using the appropriate PVC solvent-welding procedures and joining products for the DWV system.
What should I confirm before ordering?
Confirm all nominal connection sizes, the reduced branch size, H x H x H configuration, branch direction, fitting orientation, and compatibility with the planned PVC DWV system.
Important Ordering & Installation Notes
- Confirm all fitting sizes.
- Check the fitting orientation.
- Verify the reduced branch size.
- Confirm all three hub connections.
- Follow applicable DWV installation requirements.
