What is the minimum must be provided for roof drains in a building over 10,000 square feet?

3
3/4 inches
1 inch
2 inches

The correct answer is: 3/4 inches

The minimum size that must be provided for roof drains in a building exceeding 10,000 square feet is indeed 3/4 inches. This specification is grounded in plumbing codes and standards, which dictate how drainage systems should be designed to effectively handle the volume of water that may collect on larger roofs. Roof drains are critical for ensuring that water does not accumulate, as standing water can lead to structural damage and other maintenance issues. The 3/4 inch requirement provides a balance between adequate drainage capacity and practical installation considerations, ensuring that the system can adequately manage rainwater runoff and prevent potential flooding. By adhering to this size specification, plumbers help ensure that the building's drainage system is efficient, reducing the risk of overflow and optimizing water flow from the roof to the drainage system below.
