Plumbing | Western Technical College


Plumbers install, repair, and maintain the water supply, waste water treatment, drainage, and gas systems in homes, commercial and industrial buildings. The work includes plumbing tasks to assemble, install and repair pipes, fittings, and fixtures of heating, water, and drainage systems according to specifications and plumbing codes. Plumbers also install sanitary facilities, such as lavatories, toilets, tubs, bathroom fixtures, showers, kitchen fixtures, drinking fountains, and laundry equipment.

Working Conditions

Plumbing work can be indoors or outdoors in existing and newly constructed buildings, in various weather conditions, and around noise, dirt, and mud. The work requires physical strength and stamina with prolonged standing, lifting heavy pipes and equipment, and working in cramped, awkward or uncomfortable positions. Training in safety practices prevents the risk of dangers with falls from ladders, cuts from sharp tools, and burns from hot pipes or soldering equipment.
