Question

The overflow level of the secondary drain inlet above the primary drain inlet shall be not less than ______ inches above the roof?

Answer 1

The overflow level of the secondary drain inlet is typically not less than 2 inches above the primary drain inlet, according to building codes designed to prevent water damage from a failed primary drainage system.

Step-by-step explanation:

The overflow level of the secondary drain inlet above the primary drain inlet should be not less than 2 inches above the roof. This requirement is typically outlined in building codes which ensure that if the primary drainage system fails, the secondary system will handle excess water to prevent roof damage and potential interior water damage. The specific height requirement might vary based on local codes and regulations, so it's important to refer to the relevant local building codes for precise measurements.
