Description
PVC DWV Reducing Sanitary Tee (HUB x HUB x HUB)
PVC DWV Reducing Sanitary Tees provide a branch connection while transitioning between different pipe sizes in non-pressure drain, waste, and vent systems.
Featuring hub connections on all three openings, this fitting is designed for solvent-weld installation with compatible PVC DWV pipe. The reducing configuration allows a smaller branch or run connection to tie into a larger drainage system while maintaining smooth gravity-flow characteristics in residential, commercial, and institutional plumbing applications.

Connection Configuration
Main Run Inlet
The first hub accepts compatible PVC DWV pipe as part of the main drainage or vent run.
Reducing Branch
The branch connection allows a different nominal pipe size to tie into the sanitary tee while maintaining the required DWV layout.
Main Run Outlet
The opposite hub continues the main piping run with compatible PVC DWV pipe.
Construction Details
The fitting is manufactured from high-quality PVC compound for corrosion resistance, chemical resistance, and dependable long-term service in compatible DWV systems.
Hub connections on all three openings are designed for solvent-cement joining to compatible PVC pipe, creating secure permanent joints when properly installed.
The reducing sanitary tee geometry allows different pipe sizes to be connected within a branch arrangement while maintaining the intended gravity-flow characteristics of the system.
Why Choose a Reducing Sanitary Tee?
Branch & Size Transition
- Adds a branch to the DWV piping run
- Connects different compatible pipe sizes
- Reduces the need for separate reducer fittings
- Supports compact piping layouts
- Useful for new installations and repairs
PVC DWV Construction
- Corrosion-resistant material
- Lightweight construction
- Resistant to many common plumbing chemicals
- Designed for solvent-weld assembly
- Suitable for long-term non-pressure service
Typical Applications
Residential DWV Systems
- Fixture drain connections
- Waste piping branches
- Vent piping layouts
- Pipe size transitions
- Building drainage systems
Commercial & Institutional DWV
- Commercial drainage systems
- Building waste piping
- Reducing branch connections
- Repair and retrofit work
- Institutional plumbing systems
Solvent-Weld Installation
Verify the size of each hub before installation, since reducing sanitary tees may have different nominal dimensions at the branch or run connections.
Cut compatible PVC DWV pipe square, remove burrs, and clean all mating surfaces. Apply compatible PVC primer and solvent cement where required, then fully seat each pipe into the appropriate hub.
Confirm the branch orientation and pipe-size placement before the solvent cement begins to set. Allow completed joints to cure according to the cement manufacturer's recommendations before placing the system into normal service.

Our plumbing specialists can help review your main run size, branch size, DWV layout, and solvent-weld installation requirements before you order.

What is a PVC DWV reducing sanitary tee?
It is a sanitary tee designed to create a branch connection while joining compatible PVC DWV pipe of different nominal sizes.
What does HUB x HUB x HUB mean?
It means all three openings are hub or socket connections designed to accept compatible PVC DWV pipe.
How is a reducing sanitary tee different from a standard sanitary tee?
A standard sanitary tee generally connects matching nominal sizes, while a reducing sanitary tee includes at least one connection of a different nominal size.
What is the primary purpose of this fitting?
Its primary purpose is to add a branch while transitioning between different compatible pipe sizes within a DWV system.
How is the fitting installed?
All three hub connections are installed using compatible PVC solvent-weld procedures.
Is this fitting intended for pressure piping?
No. This fitting is intended for non-pressure drain, waste, and vent applications.
What material is the fitting made from?
The fitting is manufactured from durable, corrosion-resistant PVC.
Do I need a separate reducer fitting?
Not necessarily. The reducing sanitary tee already incorporates a size transition, which can eliminate the need for a separate reducer in some layouts.
What standards are referenced for this fitting?
The supplied product information references ASTM D2665, ASTM D1784, CSA B181.2, and applicable NSF/ANSI standards.
What should I verify before ordering?
Confirm the main run size, branch size, Hub x Hub x Hub configuration, and compatibility with the intended PVC DWV system.
