The maximum permissible distance between cleanouts is how many feet?

• A. 150 feet
• B. 100 feet
• C. 200 feet
• D. 250 feet

Answer: (A)

The main idea is to ensure you have practical access to clear a blockage in a horizontal drain run. Cleanouts serve as entry points for rodding or snaking the line, so the distance between them must be short enough that a typical cleaning tool can reach a clog from one cleanout to the next. In Kentucky practice, that maximum spacing is 150 feet. This limit helps keep blockages reachable and serviceable without needing excessive digging or have-to-guess locations. The distance is measured along the horizontal portion of the pipe between cleanouts, not counting vertical drops. If you have a run longer than 150 feet, you’d add another cleanout so no segment exceeds the limit.
