Which type of vent connects a drain pipe through a fitting at an angle less than 45 degrees?

• A. Roof Vent
• B. Floor Vent
• C. Side Vent
• D. Studor Vent

Answer: (C)

When thinking about vent connections in a drainage system, the way the vent ties into the drain line shows different vent types. If the vent connects to the drain through a fitting on the side of the pipe at a shallow angle (less than 45 degrees), this is called a side vent. That side connection is what distinguishes it from other vent types that go differently: a roof vent goes upward and out through the roof, a floor vent isn’t a standard vent type for a drainage run, and a Studor vent refers to an air-admittance valve installed on the drain line but not defined by a side-angle connection to the pipe. So the description of connecting through a fitting at a gentle angle points to a side vent.
