Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.[1] Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.[2] The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.[3]
In the developed world, plumbing infrastructure is critical to public health and sanitation.[4][5]
Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing.
