Tennessee Wastewater Operator Practice Exam

Which of the following is a common symptom of clogged wastewater pipes?

1. Noisy pipes

2. Slow drainage

3. Frequent power outages

4. Increased water pressure

The correct answer is: Slow drainage

Slow drainage is a common symptom of clogged wastewater pipes because obstructions in the piping system impede the normal flow of wastewater. As debris, grease, or other materials accumulate, they restrict the passage of water, causing it to drain more slowly than usual. This can result in water pooling in sinks, tubs, and other fixtures, making it evident that there is some form of blockage within the system. Other symptoms, such as noisy pipes, might occur due to changes in water flow pressure caused by a blockage, but slow drainage is the most direct and observable sign specifically associated with a clogged pipe. Frequent power outages and increased water pressure do not typically correlate with issues related to wastewater drainage. Thus, recognizing slow drainage as a clear indicator of clogged pipes helps operators effectively diagnose and address wastewater management problems.
