The distance between cleanouts shall be no longer than how many feet?

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

Answer: (A)

Access to the piping for cleaning is the key idea here. Cleanouts are placed so a plumber can reach and clear blockages with standard rods or a snake without having to push beyond the limit of the tool. The maximum distance between cleanouts is 150 feet, which keeps the cleaning access practical for typical equipment and runtimes. If cleanouts were spaced farther apart, a blockage could be beyond the reach of the tools from any cleanout, making maintenance harder. Shorter distances, like 100 feet, would still work but aren’t the standard referenced here, while longer spans such as 200 or 250 feet would risk leaving portions of the line inaccessible from a cleanout. Cleanouts are also placed at changes of direction and at key junctions to ensure accessibility throughout the system.
