What is the role of a person who oversees the work of journeyman plumbers?

The role of a person who oversees the work of journeyman plumbers is that of a master plumber. A master plumber has advanced knowledge and experience in the plumbing field, which allows them to supervise, mentor, and guide journeyman plumbers. They are responsible for ensuring that plumbing work meets all applicable codes and standards, as well as for the overall quality of the plumbing installations and repairs.

Master plumbers usually hold a higher level of certification, which grants them the authority to manage projects, handle complex systems, and take responsibility for the legal compliance of plumbing work. This position requires not only hands-on skills but also significant understanding of the plumbing code and best practices in the industry.

The other roles, such as maintenance man, journeyman plumber, and apprentice, do not carry the same level of oversight responsibility. A maintenance man typically performs repairs and service on existing systems, journeyman plumbers are skilled workers who perform plumbing tasks but do not supervise other skilled workers, and apprentices are learners who are still training and do not have the authority to oversee others.
