Spears P401 Series PVC DWV Reducing Sanitary Tee, Red
The Spears P401 Series is a PVC DWV (Drain-Waste-Vent) reducing sanitary tee engineered for hub x hub x hub solvent-weld connections in residential and commercial drainage systems. Molded from rigid red PVC, this fitting is offered in reducing configurations ranging from 1-1/2" to 3" to support a variety of branch-to-stack transitions along a drain line. The sanitary tee pattern directs waste flow in the proper downstream direction to satisfy DWV plumbing code requirements for branch, stack, and vent connections, making it a practical choice for both new installations and system repairs.
Key Features
- Trade Size: Available in reducing configurations from 1-1/2" to 3" to fit a wide range of drainage layouts and branch line transitions.
- Durable Construction: Molded from rigid PVC material that resists corrosion, chemical attack, and physical wear, providing long service life in demanding DWV applications.
- Hub x Hub x Hub Connections: Solvent-weld hub ends on all three openings create secure, leak-free joints without the need for threading or mechanical fasteners.
- Reducing Sanitary Tee Design: The sanitary pattern properly directs waste flow toward the stack, supporting compliance with DWV plumbing code requirements for branch connections.
- Red PVC Color: Distinct red coloring helps installers and inspectors quickly identify this fitting within a DWV piping run.
- Lightweight Yet Rigid: PVC construction keeps the fitting easy to handle and install while maintaining structural integrity under normal drainage loads.

Spears P401-337 – Frequently Asked Questions
1) Does the Spears P401 sanitary tee need glue, or does it thread on?
Solvent weld only. All three openings on the P401 reducing sanitary tee are hubs (Hub x Hub x Hub), so each branch takes PVC pipe cemented with primer and solvent cement. There are no threads and no mechanical fasteners anywhere on the fitting, so if your existing line terminates in a male thread you'll need a separate transition adapter ahead of this tee.
2) What trade sizes does the Spears P401 reducing sanitary tee come in?
Two order sizes are offered: 1-1/2 inch (part P401-337) and 3 inch (part P401-422). Both are reducing patterns, meaning the branch opening is smaller than the run, so give the full size call-out when you order rather than just the stack size.
3) Will this Spears tee work on a vent line as well as a waste line?
Yes. The P401 reducing sanitary tee is used for branch, stack, and vent connections in drain-waste-vent systems, so a reducing vent take-off at a stack is a normal application for it.
4) Can I use a PVC DWV tee like this in a cast iron or ABS drain line?
Not by solvent weld. The P401 is rigid PVC with solvent-weld hubs, so it only cements to PVC pipe. Tying into existing cast iron takes a shielded no-hub coupling at the transition, and ABS to PVC takes either a mechanical coupling or a transition cement, depending on what your inspector accepts.
5) Is the red color on this Spears fitting a pressure rating or just identification?
It's identification. The P401 is molded in red PVC purely so installers and inspectors can pick the fitting out in a DWV run. DWV fittings are drainage only, not for pressure service, regardless of color.
6) Where do I find the lay length and socket depth for the P401 tee?
Spears publishes the socket depths and center-to-end dimensions for its PVC DWV fittings in two dimension documents, the DWV Dimensions sheet and the PVC DWV Fittings Dimensions sheet, both linked on the product record. Pull the figures from those before you cut pipe, since a reducing tee's branch center-to-end differs by size combination.
7) Is this fitting suitable for commercial multi-story stack work or just houses?
Both. Spears lists the P401 reducing sanitary tee for residential and commercial drainage, including branch and stack transitions in multi-story buildings, as well as repair and renovation work. For property managers standardizing a building, the two sizes offered are 1-1/2 inch and 3 inch.
