To test the building sewer, a minimum head of water must be maintained for how long?

• A. 5 minutes
• B. 10 minutes
• C. 15 minutes
• D. 20 minutes

Answer: (C)

To test the building sewer, maintaining a minimum head of water for a period of 15 minutes is necessary to ensure that the sewer system is functioning correctly and to identify any potential leaks or issues. This duration allows sufficient time for the water to stabilize and for any problems to manifest, such as water leakage or inadequate drainage, which could indicate a breach in the system. Proper testing procedures are critical for ensuring the integrity of the sewer system and compliance with applicable plumbing codes and standards. Testing for this specific duration helps in confirming that the system can handle the required water flow without any failures and supports sanitation efforts by preventing backflow and environmental contamination issues.
