Georgia Septic Installer Practice Test

What is the minimum height the bottom of outlet holes should be placed above the bottom of a distribution box?

1. 1 inch

2. 3 inches

3. 5 inches

4. 7 inches

The correct answer is: 3 inches

The minimum height that the bottom of outlet holes should be placed above the bottom of a distribution box is crucial for ensuring proper drainage and function of the septic system. By setting the outlet holes at a height of at least 3 inches above the bottom of the distribution box, you help to prevent any potential issues related to standing water or sediment buildup that could hinder the flow of effluent out of the box. This height allows for the efficient movement of effluent through the outlet holes into the drain field while minimizing the risk of blockages. It also ensures that the drainage system operates effectively without overflow, which can lead to system failure and environmental contamination. Ensuring this specification is met is an essential part of maintaining the integrity and longevity of a septic installation.
