A house actually has several plumbing systems. Water supply piping brings water to the house and distributes it to fixtures and appliances, including outdoor sprinklers and irrigation.
Drain and waste plumbing disposes of used water and waste. Vent piping exhausts sewer gasses and provides proper pressure for the drainpipes. Gas piping delivers gas to gas-fired appliances. And some homes even have pipe systems that serve specialty needs-swimming pool plumbing and built-in vacuum piping, for example. In this section, we'll explore the various plumbing systems and fixtures of a house.
