The Plumbing program is one of three programs offered by the Washington, D.C. Joint Plumbing Apprenticeship Committee (UA Local 5 JATC). It is a longstanding five-year apprenticeship process that consists of approximately 1200 hours of classroom instruction in addition to full-time on-the-job training.
Plumbers install and repair water, drainage, waste & vent, as well as gas pipes in homes, businesses, and factories. They install and repair large water lines, such as those which supply water to buildings, and smaller ones, including lines that supply water to refrigerators. Plumbers also install plumbing fixtures—bathtubs, showers, sinks, and toilets—and appliances such as dishwashers, garbage disposals, and water heaters. In addition, they fix plumbing problems. For example, when a pipe is clogged or leaking, plumbers remove the clog or replace the pipe. Some plumbers maintain septic systems—the large, underground holding tanks that collect waste from houses not connected to a city or county’s sewer system.
