What size should the future vent connection be in buildings that require a main vent stack?

Half the size of the vent stack
One inch in diameter
Two inches in diameter
The same size as the full vent stack

The correct answer is: The same size as the full vent stack

In buildings that require a main vent stack, the future vent connection should be the same size as the full vent stack. This is important to ensure proper ventilation and air flow throughout the building's plumbing system. Matching the size of the future vent connection to the full vent stack helps maintain sufficient airflow to prevent drainage issues and maintain proper pressure within the system. Options A, B, and C are incorrect because they do not match the correct principle of maintaining the same size as the full vent stack for the future vent connection in buildings that require a main vent stack.
