What is the standard height above finished floor for a cleanout in a stack?

• A. 24 inches
• B. 30 inches
• C. 36 inches
• D. 48 inches

Answer: (B)

The standard height for a cleanout in a stack is set at 30 inches above the finished floor. This height is specified to provide accessibility while ensuring that the cleanout is not obstructed by other fixtures and can be easily accessed for maintenance and cleaning purposes. Setting the height at 30 inches strikes a balance between convenience for the user and practicality for plumbing maintenance, especially in residential and commercial buildings. Cleanouts installed at this height allow for effective maintenance access while reducing the risk of damages or blockages due to being placed too low or too high, which might make them harder to reach or less effective. Understanding these specifications ensures compliance with plumbing codes and contributes to the overall functionality and safety of the plumbing system.
