3. 3

4. 4

The correct answer is: 3

The correct answer regarding the maximum number of allowed inlet open wing knockouts in a precast septic tank is based on industry standards and regulations that dictate how septic systems should be designed and installed for optimal function. A precast septic tank is built with specific inlet and outlet configurations to effectively manage wastewater. Inlet open wing knockouts are designed to provide flexibility for builders when connecting the septic tank to the plumbing system. The maximum of three knockouts allows for sufficient adaptability in various installation scenarios, while still maintaining the structural integrity and functionality of the tank. This number ensures that if there are multiple configurations needed during installation, there is still a clear, designated inlet path for waste to enter the tank efficiently. Determining the maximum number of knockouts is essential to prevent issues such as uneven flow or potential backflow, which can occur if there are too many openings. By regulating the number of inlet open wing knockouts, it helps in maintaining effective treatment of wastewater, thus safeguarding public health and the environment. Understanding this aspect is crucial for effective septic system installation and compliance with Georgia's regulations.
