True
False

The correct answer is: False

The correct answer is true. According to the Illinois Plumbing Code, all main vents or vent stacks are required to connect full-size at their base to the building drain or to the main soil or waste pipe above the lowest fixture branch. This requirement ensures that the venting system functions effectively, allowing for proper air circulation and preventing any potential backpressure or siphoning issues that could compromise the drainage system. While the statement you considered may suggest otherwise, it is crucial for the integrity of plumbing systems that these connections are made appropriately. Proper sizing and connections are vital to maintaining a safe and efficient plumbing system.
