Venting Requirements - Rules of the Santee

Rules of the sanitary tee

• Sanitary tees or “Santees” are used in many different positions. However, if you don’t have an understanding about how santees actually work, you might install one incorrectly.

• Below is a Santee in the vertical position. In this situation the vent would go to the top of the fitting.

This next situation, the Santee is upside down with the side going to a branch and picking up an individual vent at the bottom.

In this situation, the Santee is located on it’s back. The vent would connect to the tee side. A fixture may not drain into the vent of a Santee in this position.
