Spears P601 Series PVC DWV Reducing Wye Fitting, Hub x Hub x Hub

The Spears P601 Series PVC DWV Reducing Wye Fitting is a three-port branch fitting engineered for sanitary drain, waste, and vent (DWV) piping systems. Molded from durable PVC and configured hub x hub x hub, this reducing wye lets an installer transition a smaller branch line into a larger main line using solvent-weld connections at all three ports. The family is available in multiple reducing size combinations, including a 3" x 3" x 2" configuration, making the P601 Series wye a core fitting for gravity drainage layouts in residential and commercial plumbing systems.

Key Features

  • Reducing Wye Configuration: Combines a full-size hub with a reduced-size branch hub, such as 3" x 3" x 2", to transition branch lines within DWV systems.
  • Durable PVC Construction: Resists the corrosion and chemical exposure common in drain, waste, and vent lines.
  • Hub x Hub x Hub Connections: All three ports accept solvent-weld hub joints for a permanent, leak-resistant bond.
  • DWV-Rated Design: Purpose-built for drain, waste, and vent piping applications rather than pressure service.
  • Wye Branch Geometry: Directs branch flow into the main line at an angled wye pattern, reducing turbulence compared to a straight tee connection.
  • Reducing Outlet: Lets a smaller-diameter branch line tie into a larger main line without an additional reducer fitting.

Technical Specifications

  • Product Type: Wye Fitting
  • Product Material: PVC
  • Connection Type: Hub x Hub x Hub
  • Refer to manufacturer dimensional documentation for complete size-specific specifications.

Typical Applications

Spears P601-338 – Frequently Asked Questions

1) What sizes does the Spears P601 PVC DWV reducing wye come in?
Two reducing combinations: 3 x 3 x 2 inch (P601-338) and 4 x 4 x 2 inch (P601-420). Both run a 2 inch branch into a larger main, so a 2 inch lav, kitchen, or laundry branch ties into either a 3 inch or 4 inch drain line without a separate reducer bushing.
2) Are the connections on the Spears P601 wye solvent weld or gasketed?
All three ports are solvent-weld hubs, configured hub x hub x hub. You prime and cement DWV pipe into each socket; there is no gasket, no thread, and no mechanical joint, so the fitting is permanent once set.
3) Do I need a separate reducer to drop a 2 inch branch into a 4 inch drain?
Not with the 4 x 4 x 2 P601 wye (part P601-420). The reduced 2 inch branch hub is molded into the fitting, so the 2 inch line cements straight in while the run stays 4 inch. Same idea on the 3 x 3 x 2 version, P601-338.
4) What is the Spears P601 wye made of, and will it hold up in a waste line?
PVC throughout the body. PVC resists the corrosion and chemical exposure typical of drain, waste, and vent lines, which is why it is standard for sanitary drainage in both residential and commercial work. It is not a fitting for hot pressurized service.
5) Where do I find socket depths and laying lengths for the Spears P601 wye?
Spears publishes size-specific dimensional data for its PVC DWV fittings in its DWV dimension sheets, which cover socket depth and center-to-end dimensions per size. Use those figures when you are laying out a 3 x 3 x 2 or 4 x 4 x 2 wye and need cut lengths.
6) Is the P601 wye suitable for a vent line as well as a waste line?
Yes. It is built for sanitary drain, waste, and vent piping, so it works in gravity waste runs and in vent stack assemblies alike, as long as the joints are solvent welded and the fitting is installed in the direction of flow.
