What is required for a drainage fixture unit on a residential toilet to function properly?

Direct waste connection without air gap
Approval from the authority
Installation of a standardized drain size
Use of PVC piping only

The correct answer is: Approval from the authority

A drainage fixture unit on a residential toilet requires approval from the authority to ensure that it meets local codes and regulations. This approval is pivotal in verifying that the installation is safe, efficient, and adheres to the standards set forth by plumbing authorities. While proper installation materials and methods are crucial—such as ensuring there are adequate drain sizes and selecting appropriate piping materials—having the necessary authority approval is fundamental. This step secures that the entire plumbing system will function as intended and protects public health standards. Plumbing codes vary by location, making it essential to consult with local authorities to confirm that the installation complies with any applicable regulations.
