What is the maximum allowable length of a vent pipe specified in Georgia plumbing codes?

• A. 10 feet
• B. 20 feet
• C. 25 feet
• D. 35 feet

Answer: (C)

The maximum allowable length of a vent pipe specified in Georgia plumbing codes is 25 feet. This length is significant for several reasons. A vent pipe is essential in a plumbing system as it allows air to enter the system to prevent vacuum formation during drainage, which can cause slow drainage or siphoning of traps. If the vent pipe exceeds the maximum length, it may not effectively equalize pressure within the plumbing system, which can lead to issues such as reduced drainage efficiency, increased chances of trap siphoning, and potential drainage system failures. The specification of a maximum length facilitates proper air circulation and ensures that the venting system operates as intended, maintaining the overall health and functionality of plumbing systems. Understanding this limit is critical for anyone involved in plumbing design or installation, as adhering to code requirements is essential for safety, functionality, and compliance with regulations.
