How should drainage lines be configured to ensure proper function?

• A. Installed at a level slope
• B. Installed with no slope
• C. Installed with a slope to ensure gravity drainage
• D. Installed vertically

Answer: (C)

To ensure proper function of drainage lines, they must be installed with a slope that facilitates gravity drainage. This configuration is crucial because it allows wastewater to flow smoothly through the pipes without pooling or backing up. A sloped installation promotes the continuous movement of solids and liquids, minimizing the risk of clogs and facilitating efficient drainage. The slope typically recommended for most drainage systems is around ¼ inch per foot, which ensures that water moves swiftly towards the designated discharge point. When drainage lines are installed with no slope, or flat, it can lead to stagnation of water, causing foul odors and potential blockages, as solids can settle and accumulate over time. Similarly, vertical installation of drainage lines is primarily reserved for specific applications like venting and does not support the flow of wastewater horizontally. Therefore, the correct configuration with a slope greatly enhances the overall performance and reliability of the drainage system.
