What key activities will apprentices and journeyworkers perform in various systems?

Apprentices and journeyworkers in pipe fitting play a critical role in ensuring the proper functioning and longevity of various systems, particularly in plumbing, HVAC, and industrial piping. The activities of installation, service, and maintenance align closely with the hands-on, practical skills these professionals need to develop.

Installing systems involves setting up pipelines, fittings, valves, and other components according to specifications and codes, ensuring that all connections are secure and leak-free. Service refers to the actions taken to troubleshoot and repair any issues that arise during the operation of these systems, requiring a strong understanding of system functionality and problem-solving skills. Lastly, maintenance involves routine checks and replacements as needed to keep systems operating efficiently and to prevent future breakdowns.

These activities are foundational in pipe fitting, as they ensure that all systems operate safely and effectively, protecting both the infrastructure and its users. The other options suggest activities that are relevant in other contexts—such as designing systems or calculating estimates—but do not capture the essence of the practical, everyday work that pipe fitting apprentices and journeyworkers engage in.
