How much rainfall per hour is required for water testing of a drainage system?

1.5 inches
2.0 inches
2.6 inches
3.0 inches

The correct answer is: 2.6 inches

For water testing of a drainage system, a rainfall rate of 2.6 inches per hour is specified as the appropriate standard. This value is established based on hydraulic principles that ensure the drainage system is tested under conditions that simulate heavy rain events. By using a 2.6 inches per hour rate, the test effectively evaluates the performance of the drainage system, including its ability to handle excess water without flooding or failure. This testing ensures that any potential weak points in the drainage system can be identified and addressed before the system is put into service. It reflects a reasonable estimate of what could occur during significant storm events, making it a practical standard for ensuring reliability and performance of plumbing systems. Understanding this rainfall rate is crucial for compliance with plumbing codes and regulations and is essential knowledge for any plumbing professional preparing for a licensing exam.
