Flat vent must be approved by the ______ before installing.

Flat vent must be approved by the ______ before installing.

• A. Department
• B. Inspector
• C. Contractor
• D. Owner

Answer: (A)

Approval of plumbing installations, especially nonstandard venting like a flat vent, comes from the department before any work begins. The department reviews plans and issues permits, ensuring the method meets code and local requirements. Once the department approves, the inspector later checks the on-site work for compliance with that approved plan. The contractor carries out the work within the permit, and the owner authorizes the project, but they don’t provide the formal code approval. This is why the correct authority for approving a flat vent before installation is the department.
