Description
PVC DWV Sanitary Reducing Street Tee (SPG x HUB x HUB)
PVC DWV Sanitary Reducing Street Tees provide a compact branch connection while transitioning between different pipe sizes in non-pressure drain, waste, and vent systems.
Featuring one spigot (SPG) connection and two hub connections, this fitting can install directly into a compatible hub fitting while also accepting compatible PVC DWV pipe at the remaining openings. The reducing configuration allows different pipe sizes to be joined within the branch arrangement while the street-style design can help reduce the need for an additional coupling.

Connection Configuration
Spigot End
The SPG connection is designed to fit directly into a compatible PVC hub fitting for a compact solvent-weld connection.
Reducing Branch Hub
The branch hub accommodates the reducing connection used to tie a different nominal pipe size into the DWV system.
Run Hub
The remaining hub accepts compatible PVC DWV pipe to continue the main piping run.
Construction Details
The fitting is manufactured from durable PVC for corrosion resistance and dependable long-term service in compatible drain, waste, and vent systems.
The combination of one spigot connection and two hub connections allows direct fitting-to-fitting installation while maintaining permanent solvent-weld joints.
The reducing sanitary configuration allows different compatible pipe sizes to be connected within the branch arrangement while smooth internal surfaces help support efficient gravity flow.
Why Choose a Sanitary Reducing Street Tee?
Branch & Size Transition
- Adds a branch to the DWV piping system
- Connects compatible pipe of different sizes
- Can reduce the need for separate reducer fittings
- Useful for compact piping layouts
- Suitable for new installations and repairs
Street-Style Configuration
- Spigot end installs directly into a hub
- Can reduce the need for an additional coupling
- Supports fitting-to-fitting installation
- Useful where space is limited
- Maintains solvent-welded connections
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 nominal size of each connection before installation, since sanitary reducing street tees may use different pipe sizes at the branch or run openings.
Clean and prepare all mating PVC surfaces according to accepted solvent-weld procedures. Apply compatible PVC primer and solvent cement where required, then fully seat the spigot connection into its mating hub and insert compatible pipe into the two hub connections.
Confirm branch orientation and size placement before the solvent cement begins to set. Allow all 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, spigot and hub connections, and DWV layout before you order.

What is a PVC DWV sanitary reducing street tee?
It is a sanitary street tee designed to create a branch connection while joining compatible PVC DWV pipe of different nominal sizes.
What does SPG mean?
SPG means spigot. The spigot end is designed to fit directly into a compatible hub fitting.
What does HUB mean?
Hub refers to a socket connection designed to accept compatible PVC DWV pipe for solvent-weld installation.
How is this different from a standard sanitary street tee?
The reducing version includes at least one connection of a different nominal size, allowing a pipe-size transition within the branch arrangement.
Why use a street-style fitting?
The spigot connection can install directly into another hub fitting, which may eliminate the need for an additional coupling or short pipe section.
Do I need a separate reducer fitting?
Not necessarily. The fitting incorporates a size transition, which may eliminate the need for a separate reducing fitting in some layouts.
How is the fitting installed?
The spigot and 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 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 every nominal connection size, the Spigot x Hub x Hub configuration, which connection is reduced, and compatibility with the intended PVC DWV system.
