What are the requirements for a floor flange used for a toilet or similar fixture composed of brass?

  1. Minimum thickness of 1/16" inch

  2. Minimum thickness of 1/8" inch

  3. Minimum caulking depth of one inch

  4. Minimum caulking depth of two inches

The correct answer is: Minimum thickness of 1/8" inch

The requirement for a floor flange made of brass that is used for a toilet or similar fixture is a minimum thickness of 1/8 inch. This specification ensures that the flange is sturdy enough to support the fixture and withstand the stresses of frequent use without bending or breaking. A thicker flange contributes to the overall integrity and durability of the installation, allowing it to maintain a secure connection between the plumbing system and the toilet or fixture. This thickness also helps to provide a robust surface for sealing, which is essential in preventing water leaks. Understanding the significance of the 1/8 inch minimum thickness is crucial for proper installation and compliance with applicable plumbing codes, which prioritize safety and reliability in plumbing systems.
