Plumbing is a field that deals with piping systems and fixtures. This type of work is vital for regulating water usage and ensuring hygiene. Properly functioning plumbing systems also help reduce water bills. Proper plumbing also prevents mold and rot. This profession can be found in many different fields, including building and construction.

Plumbing systems are comprised of a number of components, including pipes, fittings, and valves. The main part of the plumbing system is the water supply line, which provides potable water to the rest of the house. This pipe comes from a reservoir or municipal water system, or from a private well. The pipes also transport waste, such as sewerage and stormwater.

In addition to pipes and faucets, plumbers also install water meters, pumps, expansion tanks, and back flow preventers. They also install water softeners, UV sterilization lights, and water filters. Moreover, plumbers use tools such as heat exchangers, gauges, and control systems. Many of these tools are hidden from public view, making them essential to a plumbing job.

Drains are another vital part of plumbing. They help keep the pressure of wastewater in the drainage system neutral, preventing toxic gases from accumulating inside the house. During a flood, a sump pump can help remove excess water from a basement. It is located in the crawl space or basement. The supply and drainage subsystems are two separate operations, and the plumbing technicians working on them must have a good understanding of each.
