What is the maximum distance a cleanout opening should be from a change in direction greater than 45 degrees?

The maximum distance a cleanout opening should be from a change in direction greater than 45 degrees is 10 feet. This requirement is established to facilitate access for maintenance and cleaning of the plumbing system.

When there are changes in direction in a piping system, especially those exceeding 45 degrees, the likelihood of clogs or material buildup increases. Having a cleanout within a reasonable distance (i.e., 10 feet) ensures that technicians or maintenance personnel can easily access the piping for inspections or to remove blockages without excessive effort. This practice not only supports efficient plumbing maintenance but also aligns with code regulations designed to promote the longevity and reliability of plumbing systems.

In contrast, options suggesting that the distance could be 5, 15, or 20 feet would not provide the same level of accessibility and could potentially make maintenance more challenging, increasing the risk of plumbing issues going unnoticed for longer periods. This is why the 10 feet distance is recognized as optimal in maintaining operational efficiency and ensuring code compliance in plumbing systems.
