Plumbers plan, install, and service plumbing systems, fixtures, piping equipment and controls. These piping systems may be used to transport water, waste, gases, or hot liquids.
Plumbing is one of the pipe trades. Pipe trades deal with the installation, maintenance and repair of piping systems. Although there are common tasks in each of the pipe trades, there are differences in where the work is performed, the types of piping involved and the qualifications required.
