Thus, these workers will always have some work. Job opportunities for skilled workers should be good since the supply of trained plumbers and pipe fitters is smaller than the demand. Many jobs will open each year as current workers retire or leave this occupation for other reasons. Preparation Almost all plumbers gain their skills during apprenticeships sponsored by unions or contractors. Apprenticeships generally last four to five years and include at least 144 hours of classroom instruction each year.
Courses cover drafting and blueprint reading, math, applied physics, and chemistry.
Other courses include safety and local plumbing codes and regulations. On the job, apprentices start by learning basic skills, such as identifying grades and types of pipe. Other basic skills are using the tools of the trade and safely unloading materials. As apprentices gain experience, they learn how to work with various types of pipe and install different piping systems and plumbing fixtures. Apprentices gain thorough knowledge of all aspects of the trade.
