PLUMBING AND PIPE FITTING
Plumbers and pipe fitters assemble, install, and make changes in pipe systems used to carry water, steam, air, and other liquids and gases. They install plumbing fixtures, such as bathtubs and toilets. They also install heating and refrigeration units. Plumbing and pipe fitting are generally considered to be separate trades, though many qualified craft workers are skilled in both fields. Many plumbers and pipe fitters work for contractors on the construction of new buildings, while others are steadily employed by plants and factories to do maintenance work. Plumbers and pipe fitters may work on the construction of ships and airplanes. Plumbers may also connect the water, gas, and waste disposal pipes to the city or town supply. Before installing plumbing, plumbers study blueprints to see what kind and size of pipes are needed. They install plumbing in a new building in three basic steps. The first step is to run pipes inside the foundation before the concrete is poured. These pipes are used for water and waste. The second step is to install the pipes for the kitchen and bathroom. This is done after the carpenters have built the frame of the building. The plumbers must drill holes through the framework to run the pipes. The pipes must be bent, cut, and then connected to each other with solder or glue. Copper pipe, used for water and heat, is joined by soldering. Plastic pipe, used for waste lines and air venting, is joined with glue. After the piping has been installed, plumbers must check for leakage. To do this, plumbers cap all the pipe outlets and then pump air through the system to check for loss of pressure. After the walls have been installed, the plumbers complete the final step. They put in plumbing fixtures, such as bathtubs, sinks, and toilets. When these fixtures Pipe fitters install, maintain, and repair large pipes such as those used in industrial settings.
