True or False: A cleanout is required for each and every change in direction of the sewer drainage pipe.

The statement regarding cleanouts in sewer drainage systems is indeed false. While cleanouts are vital access points for maintenance and clearing blockages in drainage pipes, they are not required at every single change in direction.

The plumbing codes typically require cleanouts to be installed at specific intervals and locations, primarily where there are significant bends, changes in direction, and at points where the pipe transitions to a vertical stack. Additionally, cleanouts are generally mandated at intersections and at the base of vertical stacks to ensure accessibility. However, minor changes in direction that do not pose a high risk of blockage may not necessitate a dedicated cleanout.

Furthermore, while large diameter pipes may have specific requirements for cleanouts due to their potential to carry larger volumes of waste, it’s not accurate to state that they are needed for every change or that cleanouts are only for visible changes. Overall, the requirement for cleanouts in sewer systems is guided more by practicality and code provisions than by an absolute rule related to every directional change in the piping.
