Spears P416-420 4X4X4X2 PVC DWV Reducing Santee with Left Side Inlet
The Spears P416-420 is a 4X4X4X2 PVC DWV reducing santee fitting engineered with a left side inlet, providing a reliable branch connection point for drain, waste, and vent piping systems. Constructed from PVC for corrosion resistance and long-term durability, this fitting is designed for use in residential and commercial plumbing systems where a reduced side inlet connection is required. The reducing santee configuration allows plumbers to tie in a smaller diameter branch line while maintaining proper flow through the main drainage run.
Key Features
- Pipe Size Configuration: 4X4X4X2 sizing accommodates a 4-inch main run with a 2-inch reduced side inlet connection for flexible branch tie-ins.
- PVC DWV Construction: Manufactured from PVC material engineered specifically for drain, waste, and vent applications, offering corrosion and chemical resistance.
- Left Side Inlet Design: Integrated left side inlet allows for a secondary branch connection without requiring additional fittings.
- Reducing Santee Configuration: Combines a sanitary tee body with a reduced inlet opening, simplifying transitions between differing pipe diameters in a single fitting.
- Solvent-Weld Connections: Designed for standard PVC solvent cement joining methods common to DWV piping systems.
- Lightweight, Durable Material: PVC construction provides a lightweight yet durable alternative to metal fittings, easing handling and installation.
- Simplified Installation: Combines multiple fitting functions into a single component, reducing the number of joints required in DWV rough-in work.
- Space-Saving Fitting: Reducing santee design helps consolidate branch connections in tight plumbing chases and wall cavities.

Spears P416-420 – Frequently Asked Questions
1) What do the four sizes in the Spears P416-420 santee mean?
The P416-420 is a 4 x 4 x 4 x 2 DWV sanitary tee: the main run inlet, outlet, and branch are all 4 inch, and the fourth opening is a 2 inch reduced side inlet. So you keep a full 4 inch drainage run while picking up a 2 inch branch, typically a lavatory, tub, or shower waste, without cutting in a separate fitting.
2) Is the side inlet on the Spears P416-420 on the left or right?
Left side inlet. Orientation is fixed in the molded body, so you have to decide which way the branch faces before you order: with the fitting installed vertically in the drainage run and the 4 inch branch facing you, the 2 inch inlet comes in on the left. If the fixture waste approaches from the other side, you need the right-hand version of the P416 series instead.
3) Will a sanitary tee work for a horizontal-to-horizontal drain connection?
No, and that catches people out. A sanitary tee like the P416-420 is for a horizontal branch entering a vertical stack, or for venting. For a horizontal line tying into another horizontal line you want a combination wye and 1/8 bend, because the sanitary tee's branch sweep will not carry solids on the flat. The 2 inch side inlet on this fitting is intended to pick up a fixture or vent branch on the stack, not to replace a wye.
4) How does the Spears P416-420 DWV santee get joined to the pipe?
Solvent weld hub connections on all openings. It takes standard PVC DWV primer and cement, same process as the rest of the run, with no gaskets, threads, or mechanical joints involved. The 2 inch side inlet is cemented the same way as the 4 inch hubs.
5) Do I still need a reducing bushing for the 2 inch branch on this Spears santee?
No. The 2 inch inlet is molded into the body, so the reduction is built in. Cement 2 inch DWV pipe straight into that hub. That is the point of the reducing santee, it replaces a tee plus a bushing or a reducer and takes one or two joints out of the rough-in.
6) What is the exact part number to order this 4x4x4x2 left-inlet DWV santee?
Spears P416-420. It is the 4 x 4 x 4 x 2 PVC DWV reducing santee with the left side inlet, in the P416 series of side-inlet santees. Quote that number to keep the inlet hand and the 2 inch reduction correct, since the series covers several size and orientation combinations.
7) Is this Spears fitting suitable for multi-family and light commercial drainage, or just residential?
Both. The P416-420 reducing santee is used in residential DWV, commercial plumbing installations, multi-family residential, light commercial renovation, new construction rough-in, and repair or retrofit work. For a property manager standardizing stack fittings across units, it is the same part whether the building is a single house or an apartment block.
8) Will PVC DWV hold up in a corrosive waste line better than cast iron?
PVC is the reason many retrofits move off metal. The P416 series body is PVC engineered for DWV service, giving corrosion and chemical resistance in waste and vent lines, and it is far lighter to handle and hang than a metal fitting of the same size, which matters on a 4 inch stack in a tight chase.
