What is a potential consequence of improperly installed sewer pipes?

Improperly installed sewer pipes can lead to significant issues, one of the most serious being flooding and leaks. When sewer pipes are not installed correctly, they may fail to maintain the appropriate slope, which is essential for proper drainage. This can result in blockages, causing sewage to back up into homes or overflows into the surrounding environment.

Inadequate sealing at joints or connections can also lead to leaks, allowing wastewater to seep into the ground, which can contaminate groundwater and create health hazards. Additionally, flooding may occur when excessive rain or water usage overwhelms the drainage system, particularly if the sewer lines are not capable of handling the flow properly, further exacerbating the situation.

The other options are not direct consequences of improper sewer pipe installation. Increased water pressure may be related to supply lines rather than sewer lines, while improved drainage contradicts the very premise of improper installation. Higher energy consumption is also more applicable to systems like pumps or heating rather than sewer pipe installation issues.
