Plumbers install, alter and repair the systems that keep our water and waste disposal systems running, and that provide many of the basic amenities we rely on day-to-day. They read and interpret blueprints and project specifications. Plumbers also select the type and size of pipe required for a project and measure, shape and join pipes according to the appropriate specifications. They sometimes alter structures to accommodate the pipes. Plumber is a nationally designated trade under the Inter-provincial Red Seal program.

Once pipes are in place, plumbers test for leaks. After installation, they maintain pipes to prevent or repair leaks. Some Plumbers also braze and weld metal. A Plumber’s specialization is based on his or her knowledge of the substance being carried. For example, the handling of water is very different from steam, or chemicals, or natural gas. And residential plumbing is distinct from industrial or commercial work.

Plumbers often work in the construction industry, laying new pipe for buildings or doing extensive renovations to large buildings. Residential Plumbers install and repair plumbing fixtures, such as bathtubs, showers, sinks, and toilets, and appliances such as dishwashers and water heaters.

Plumbers use a variety of materials and construction techniques, including copper, steel and, (increasingly) plastic pipe. They also work with large cast iron and concrete pipes. Plumbers also sometimes make use of other related skill sets, such as a familiarity with basic welding and electrical work and a limited amount of gasfitting work.
