Massachusetts Plumbers Journeyman Practice Exam

Where should accessible cleanouts be installed concerning changes of direction in drainage systems?

At every change of direction At every 90-degree change of direction At every 45-degree change of direction At every 60-degree change of direction

Correct Answer:

At every change of direction

Explanation:

The installation of accessible cleanouts at every change of direction in drainage systems is essential for ensuring proper maintenance and cleaning access. Cleanouts facilitate the removal of blockages and provide a means for inspection and maintenance of sewer and drainage lines without needing to excavate or dismantle significant portions of the system. By placing cleanouts at every change in direction, whether it is a sharp bend, a gradual curve, or any angle, it ensures that there are multiple access points to the drainage system. This approach minimizes the risk of clogs and makes it easier for plumbers to address issues efficiently. It also adheres to best practices and plumbing codes, which often mandate accessibility for easy maintenance in drainage systems.
