SKILLS AND APTITUDES NEEDED

Basic knowledge in mathematics, drafting, blueprint reading, computers, and physics Good physical condition

Plumbers install and repair the water, waste disposal, drainage, and gas systems in homes and commercial and industrial buildings. They also install plumbing fixtures—bathtubs, showers, sinks, and toilets—and appliances such as dishwashers and water heaters.

Pipefitters install and repair both high and low-pressure pipe systems used in manufacturing, in the generation of electricity, and in heating and cooling buildings. They also install automatic controls that are increasingly being used to regulate these systems.

Residential water systems use copper, steel, and plastic pipe that can be handled and installed by one or two workers. Municipal sewerage systems are made of large cast iron pipes so installation normally requires crews of pipefitters. Because plumbers and pipefitters frequently must lift heavy pipes, stand for long periods, and sometimes work in uncomfortable or cramped positions, they need physical strength as well as stamina. They may have to work outdoors in inclement weather and they are subject to possible falls from ladders, cuts from sharp tools, and burns from hot pipes or soldering equipment.
