Systems
The major categories of plumbing systems or subsystems are:
- Potable cold and hot tap water supply
- Plumbing drainage venting
- Septic systems
- Rainwater, surface, and subsurface water drainage
- Fuel gas piping
For their environmental benefit and sizable energy savings, hot water heat recycling units are being installed in residential buildings. Ecological concerns and water shortages have increased interest in graywater recovery and treatment systems.
Plumbing may also include hydronics, which involves heating and cooling systems utilizing water to transport thermal energy. The New York City steam system is an example of a large district heating system.

Famous quotes containing the word systems:
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
“I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
—Anne Sullivan (1866–1936)
