A vent pipe is not required for a waste line if the system is designed to maintain proper drainage and air flow without it, typically in cases of short horizontal runs or when using specific types of fixtures that allow for air to enter the system naturally. Additionally, modern Plumbing systems often incorporate features like air admittance valves (AAVs) that serve the same purpose as a vent by allowing air to enter the drainage system while preventing sewer gases from escaping. However, local building codes should always be consulted, as regulations may vary.

Depends on the code and how its plumbed in. Your only allowed so much footage on the drain line before it will have to be individually vented on a combination waste and vent system. Also the pipes will have to be sized at least 2 pipe sizes larger.
Can you provide a detailed toilet drain diagram for better understanding of the plumbing system?
A detailed toilet drain diagram shows how waste from the toilet flows through the plumbing system. It typically includes the toilet bowl, trap, waste pipe, vent pipe, and main sewer line. The waste is flushed down the toilet bowl, goes through the trap to prevent sewer gases from entering the home, then flows through the waste pipe to the main sewer line. The vent pipe allows air to enter the system, preventing suction and ensuring proper drainage. This diagram helps understand how the plumbing system works to remove waste from the toilet effectively.
