How long should Air Chambers installed in a fixture Supply be according to the Illinois Plumbing Code?

The correct answer is: 12"

According to the Illinois Plumbing Code, air chambers installed in a fixture supply should be a minimum length of 12 inches. This specification helps to ensure that the air chamber can effectively absorb shock and prevent water hammer caused by sudden changes in water pressure. Water hammer can lead to damage within the plumbing system, so adhering to this standard is important for maintaining the integrity and longevity of the plumbing infrastructure. Options that suggest shorter or longer lengths may not align with the requirements set forth in the code, which emphasizes the effectiveness of a properly sized air chamber in mitigating the issues associated with water hammer.
