Description
Horizontal Twin Tee 3" x 3" x 1-1/2" x 1-1/2"
Horizontal Twin Tee 3" x 3" x 1-1/2" x 1-1/2" is designed for DWV piping layouts that require two opposing 1-1/2" branch connections entering a 3" horizontal drainage run. The twin-tee configuration combines multiple drainage connections into a single fitting for a compact installation.
With a 3" x 3" main run and two 1-1/2" branches, this fitting provides a convenient solution for connecting two compatible branch lines into the same drainage assembly. Proper sizing, orientation, and installation are important for maintaining the intended flow path through the DWV system.

3" Main Drainage Run
The fitting incorporates a 3" x 3" main run for installation within a compatible drainage line. This provides the primary flow path through the fitting while accepting the two smaller branch connections.
Confirm the 3" main-line size before installation and make sure the fitting orientation matches the intended drainage layout.
Dual 1-1/2" Branch Connections
Two 1-1/2" branch connections allow separate compatible drainage lines to enter the same fitting. The opposing branch arrangement can simplify piping layouts that would otherwise require several individual fittings.
Verify both branch-line sizes and the required connection orientation before ordering to ensure the twin tee matches the planned system configuration.
Horizontal Twin Tee Configuration
The horizontal twin tee configuration is specifically arranged for applications where two branch connections must enter a common horizontal drainage assembly.
Because drainage fittings depend on proper directional installation, confirm the fitting orientation and intended flow arrangement before completing the piping system.
Compact Multi-Branch Connection
Combining the main run and two branches into a single four-opening fitting can reduce the number of separate fittings needed to create a multi-branch drainage connection.
This compact configuration can simplify installation where available piping space is limited while keeping both 1-1/2" branches connected to the common 3" run.
Installation & Selection Considerations
- Confirm all four sizes.
- Verify the horizontal orientation.
- Confirm both 1-1/2" branch connections.
- Check compatibility with the DWV piping system.
- Follow applicable drainage installation requirements.
Our DWV fitting specialists can help review your 3" main drainage run, two 1-1/2" branch connections, fitting orientation, available installation space, and overall piping configuration before you order.
Frequently Asked Questions
What size is this horizontal twin tee?
This fitting is sized 3" x 3" x 1-1/2" x 1-1/2", with a 3" main run and two 1-1/2" branch connections.
How many branch connections does this fitting have?
It has two branch connections, both sized 1-1/2".
What size is the main run?
The main run uses 3" x 3" connections.
Why is it called a twin tee?
The twin-tee configuration provides two branch connections entering a common main-run fitting rather than the single branch found on a standard tee.
Is this fitting designed for horizontal installation?
Yes. This product is identified as a horizontal twin tee and should be selected and oriented for the intended horizontal DWV piping arrangement.
Can the two branches connect separate drain lines?
Yes. The two 1-1/2" branches are arranged to connect compatible branch lines into the common 3" drainage fitting.
Why is fitting orientation important?
DWV fittings depend on the correct orientation to direct drainage through the intended flow path, so the piping layout should be confirmed before installation.
What should I confirm before ordering?
Confirm the 3" x 3" main run, both 1-1/2" branches, horizontal orientation, connection requirements, and compatibility with the intended DWV system.
Important Ordering & Installation Notes
- Confirm all fitting sizes.
- Verify both branch sizes.
- Confirm the horizontal orientation.
- Check the complete DWV piping layout.
- Install according to applicable drainage requirements.
