Description
PVC DWV Reducing Street Wye (SPG x H x H)
PVC DWV Reducing Street Wye (SPG x H x H) provides an angled reducing branch connection within compatible PVC drain, waste, and vent piping. The street wye configuration combines one spigot connection with two hub connections while providing a transition between the selected nominal sizes.
The SPG x H x H reducing street wye configuration combines different connection interfaces and a reducing branch arrangement within one PVC DWV fitting. Selection should account for all nominal sizes, spigot and hub compatibility, branch orientation, adjoining components, joining requirements, piping alignment, support, and available installation clearance.

Reducing Street Wye Design
The reducing street wye configuration provides an angled branch while incorporating different nominal connection sizes within the fitting. The street-style spigot connection can connect directly into an appropriately sized compatible receiving hub.
The fitting orientation should be established before permanent joining so the main run and reducing branch correspond with the intended piping layout. Planning the position helps coordinate adjoining components, nearby fittings, support, and available working clearance.
Spigot & Hub Connections
The spigot connection fits into an appropriately sized compatible receiving hub, while the two hub connections receive compatible PVC DWV pipe. Each opening should be matched carefully to the correct nominal size and adjoining component.
The mating surfaces should be prepared using the appropriate PVC DWV joining procedure. Proper insertion, compatible joining materials, correct fitting orientation, and careful alignment help establish the connections without unnecessary stress on the fitting.
PVC DWV Integration
The PVC DWV construction allows the reducing street wye to integrate into compatible drain, waste, and vent piping arrangements. Matching all nominal sizes and connection interfaces to the adjoining components 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
A PVC DWV Reducing Street Wye combines an angled branch, reducing configuration, and street-style spigot connection within one fitting. This arrangement provides a compact transition where the branch and adjoining piping require different selected nominal sizes.
Installation planning should consider spigot engagement, branch orientation, adjoining pipe alignment, nearby fittings, available clearance, and piping support. Connected components should align naturally without forcing the fitting into position.
Installation & Selection Considerations
- Confirm all nominal sizes.
- Verify the SPG x H x H arrangement.
- Check PVC DWV compatibility.
- Confirm the reducing branch orientation.
- Match each connection before assembly.

Our PVC fitting specialists can help review your nominal sizes, DWV requirements, SPG x H x H configuration, adjoining components, reducing branch orientation, joining requirements, piping alignment, support requirements, and available installation clearance before you order.
Frequently Asked Questions
What is a PVC DWV Reducing Street Wye used for?
It provides an angled reducing branch connection within compatible PVC DWV piping while incorporating a street-style spigot connection.
What does SPG x H x H mean?
It identifies one spigot connection and two hub connections within the fitting configuration.
Why is this fitting called reducing?
The fitting incorporates different selected nominal connection sizes within its branch configuration.
What connects to the spigot end?
The spigot end fits into an appropriately sized compatible receiving hub.
Does branch orientation matter?
Yes. The fitting should be positioned so the angled reducing branch corresponds with the intended piping layout.
What should I confirm before ordering?
Confirm all nominal sizes, the SPG x H x H arrangement, PVC DWV compatibility, and required branch orientation.
Important Ordering & Installation Notes
- Inspect all connections before use.
- Confirm each nominal connection size.
- Verify the SPG x H x H arrangement.
- Prepare adjoining components correctly.
- Set the branch orientation before assembly.
