Double Sanitary Tee Design
The double sanitary tee configuration provides a main piping run with branch connections extending from opposite sides of the fitting. This allows multiple compatible PVC DWV pipe sections to meet within one fitting while maintaining the specified reducing arrangement.
The fitting orientation should be established before permanent joining so all four hub connections correspond with the intended piping layout. Planning the installation helps coordinate branch direction, adjoining pipe lengths, nearby fittings, support, and available working clearance.
Four Hub Connections
The hub connections receive appropriately sized compatible PVC DWV pipe at all four openings. Because the fitting is reducing, every hub should be matched carefully to the correct nominal pipe size before permanent assembly.
The mating pipe and hub surfaces should be prepared using the appropriate PVC DWV joining procedure. Compatible joining materials, proper insertion, correct fitting orientation, and careful alignment help establish the connections without placing unnecessary stress on the fitting.
PVC DWV Integration
The PVC DWV construction allows the reducing double sanitary tee to integrate into compatible drain, waste, and vent piping arrangements requiring opposing branches. Matching every nominal size and hub interface to the adjoining PVC pipe helps maintain the intended piping configuration.
Application suitability should be evaluated using the requirements of the complete DWV system. Adjoining materials, connection compatibility, joining materials, piping support, slope where applicable, and local installation requirements should all be considered during fitting selection.
Reducing Branch Configuration
The reducing configuration allows the fitting to incorporate different specified nominal connection sizes while maintaining the double sanitary tee arrangement. This can provide the required size transition without adding separate reducing fittings at the branch location.
Installation planning should consider every connection size, branch orientation, adjoining pipe alignment, nearby fittings, available clearance, and piping support. Connected piping should align naturally so the fitting is not relied upon to correct offsets or support improperly positioned pipe.
Installation & Selection Considerations
- Confirm every nominal size.
- Verify the H x H x H x H arrangement.
- Check PVC DWV compatibility.
- Confirm the required reducing configuration.
- Set both branch orientations before assembly.
Our PVC fitting specialists can help review every nominal size, DWV requirements, H x H x H x H configuration, required reduction, adjoining PVC pipe, branch orientation, joining requirements, piping alignment, support requirements, and available installation clearance before you order.

Reducing Double Sanitary Tee Configuration
The reducing double sanitary tee configuration combines a straight-through main run with two opposing sanitary branches of a reduced nominal size. This provides a single fitting for connecting two smaller branch lines into a larger common PVC DWV line.
The reducing arrangement should be matched to the actual main and branch pipe sizes rather than treated as a same-size double sanitary tee. Confirming each connection before installation helps ensure the larger run and smaller branches are positioned correctly within the drainage layout.
Four-Hub Connection Design
The fitting uses an H x H x H x H configuration, providing four receiving hub connections for compatible PVC piping or mating spigot-ended components. Two hubs continue the main run while the remaining two provide the opposing reduced sanitary branch connections.
All four adjoining connections should be considered during layout because movement becomes limited as the assembly is completed. Dry-positioning the fitting with the main and branch piping helps establish insertion positions and branch alignment before permanent joining.
Opposing Reduced Branches
The opposing reduced branches allow smaller drainage or vent lines to approach the larger main run from opposite sides at a common fitting location. This arrangement can simplify piping layouts that would otherwise require multiple reducing and branch fittings.
Both branch directions should be reviewed together because nearby framing, fittings, and other piping may affect the available installation space. Maintaining adequate clearance on each side helps keep the reduced branches aligned with their intended adjoining piping.
Main & Branch Size Planning
A reducing fitting requires the main-run and branch dimensions to be identified separately before ordering. The larger main connection and smaller opposing branch connections should correspond with the actual pipe sizes specified for the DWV installation.
Reviewing the complete piping layout helps prevent a same-size fitting from being selected where a reduction is required. It also helps establish the correct orientation before the fitting is permanently incorporated into the main drainage run.
Installation & Selection Considerations
- Confirm the main-run size.
- Check clearance on both sides.
- Identify both reduced branch sizes.
- Verify all four connections require hubs.
- Match the branch orientation to the DWV layout.
Our PVC DWV fitting specialists can help review your main-run size, reduced branch sizes, four-hub configuration, opposing branch locations, adjoining PVC piping, available clearance, and overall drain, waste, and vent layout before you order.
Frequently Asked Questions
What is a PVC DWV Reducing Double Sanitary Tee used for?
It connects two opposing reduced-size branch lines into a common larger PVC DWV main run.
What does H x H x H x H mean?
It means the fitting provides four hub connections for compatible PVC pipe or mating spigot-ended components.
Why is this called a reducing double sanitary tee?
The fitting combines two opposing sanitary branches with a main run while using reduced-size branch connections relative to the larger main piping.
How many branch connections does the fitting provide?
It provides two opposing sanitary branch connections in addition to the two connections forming the straight-through main run.
Are all four connections hubs?
Yes. The H x H x H x H designation identifies an all-hub connection configuration.
How is this different from a standard double sanitary tee?
This reducing version connects smaller branch piping to a larger main run, while a standard double sanitary tee may use the same nominal size throughout its connections.
Why should both branch locations be checked before installation?
The branches extend from opposite sides, so both adjoining lines need sufficient clearance and proper alignment with the main DWV run.
What should I confirm before ordering?
Confirm the main-run size, both reduced branch sizes, four-hub configuration, branch directions, and available installation clearance.
Important Ordering & Installation Notes
- Keep the main run properly aligned.
- Dry-position all four connections first.
