Georgia Septic Installer Practice Test

What configuration allows for multiple outlet connections in a distribution box?

1. Knockouts positioned 7 inches apart

2. Knockouts positioned 9 inches apart

3. Knockouts positioned 12 inches apart

4. Knockouts positioned 15 inches apart

The correct answer is: Knockouts positioned 9 inches apart

The configuration that allows for multiple outlet connections in a distribution box is determined by the spacing of the knockouts. When knockouts are positioned 9 inches apart, it provides an optimal distance to accommodate standard outlet connections, ensuring that waste can be effectively distributed to multiple drain lines. This spacing allows for flexibility in system design, enabling connections to various lines without compromising the effective flow of effluent from the septic tank. This 9-inch spacing is particularly relevant in meeting local regulations and ensuring proper operation of the septic system. It helps in maintaining appropriate hydraulic loading on each line, which is crucial for avoiding issues such as overloading or underloading individual drain fields. By facilitating multiple outlet connections, the design promotes balanced distribution and enhances the overall efficiency of the septic system.
