| Feature | PVC Sanitary Tee (Oblique Tee) | PVC Straight Tee (90° Tee) |
|---|---|---|
| Primary Purpose | Connecting drainage branches to main lines in DWV systems. | Creating perpendicular connections in pressure systems (e.g., water supply) or vent lines. |
| Branch Angle | Typically 45° or 87° from the main run. | 90° from the main run. |
| Flow Path Design | Features a curved inlet to guide wastewater smoothly into the main flow. | Has a sharp, right-angled turn. |
| Key Application Rule | Should be used for horizontal-to-horizontal or vertical-to-horizontal waste connections. | Should only be used for vertical-to-vertical connections (like vent lines) in DWV systems. Using it in horizontal waste lines is a common plumbing error that leads to clogs. |
| Common Standards | ASTM D2665 (for DWV piping); often carries cUPC or UPC certification. | Various pressure or conduit standards. |
Technical Specifications & Applications
Material & Standards: They are made from PVC (polyvinyl chloride) and manufactured to standards like ASTM D2665 for DWV applications. Look for cUPC or UPC certification, which indicates approval for plumbing use in North America.
Key Applications: Their main use is in residential and commercial drain lines to connect fixtures (like sinks, showers, and toilets) to soil stacks or main drains. A specific code-mandated application is inside grease interceptors, where a vertical sanitary tee is used to direct incoming wastewater downward.
Installation Notes: Sanitary tees are designed for non-pressure, gravity-flow systems. The connection must be oriented correctly: the curved branch should point in the direction of the main flow to guide waste smoothly. Connections are typically made using solvent cement for a permanent, watertight seal.
How to Choose the Right Fitting
For your project, selecting the correct fitting depends entirely on the type of system and the direction of flow:
For Drainage/Waste Pipes: Always use a sanitary tee (45° or 87°) when connecting a horizontal branch to a horizontal or vertical main drain line. This ensures proper flow and minimizes blockages.
For Vent Pipes: A straight tee (90°) is acceptable and commonly used for connecting vent lines, as these pipes only carry air and no waste.
For Pressure Systems: If you are working on a pressurized water supply line, use a standard PVC pressure tee, not a DWV sanitary tee.
