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

The statement that a cleanout is required for every change in direction of the sewer drainage pipe is false. Cleanouts are access points in a drainage system that allow for the removal of blockages and facilitate maintenance. However, plumbing codes typically do not mandate the installation of a cleanout for every single change in direction of the pipe.

For practical purposes, cleanouts are required at certain intervals, particularly at significant changes in direction, such as bends or turns in the piping that are typically 90 degrees, as well as at the base of vertical stacks and at specific intervals along long runs of horizontal drainage pipe. The requirements can vary depending on the local building codes, but generally, the intention is to ensure that the plumbing system remains accessible for maintenance while not overburdening the system with unnecessary cleanouts.

The options that suggest the need for a cleanout based on every change in direction or exclusively for vertical changes do not align with the broad understanding of cleanout requirements in plumbing systems. Therefore, the correct assessment is that it is indeed false that every change in direction requires a cleanout.
