Plumbing is an important aspect of any home. Having a basic understanding of plumbing can save you time and money when it comes time to fix it. Plumbing is basically a system of pipes and fixtures that transport water throughout a building. Plumbing is also a profession, where professionals install and repair the plumbing systems in homes.

The plumbing system consists of two main subsystems: the supply system, which delivers water into the house, and the drainage system, which removes wastewater. Water flowing into a home is under pressure and passes through a meter that records how much water is being used. The main water shutoff valve is located near the meter, and must be shut off if there is a plumbing emergency.

Different types of pipes are used for different plumbing systems. A professional plumber needs to know which type of pipe is appropriate for which plumbing system. An associate degree program in plumbing and heating technology includes theory and hands-on lab experience. For example, students will learn about chlorinated polyvinyl chloride (PVC) pipe, which is used for water distribution systems. Its chlorine-based composition makes it more resistant to heat and fire.

Plumbing professionals play a vital role on construction sites. A plumbing consultant can give the plumber a design that matches the building’s needs. The plumber will then install the piping systems.
