Basic Principles of the Plumbing Code
The Plumbing Code aims to ensure public health and safety through proper installation and maintenance of plumbing systems.
Key Definitions
- Air Gap (Drainage): The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture, or other device and the flood level rim of the receptacle.
- Backflow: The flow of water or other liquids, mixtures, or substances into the distributing pipes of a potable supply of water from any source or sources other than its intended source.
- Trap: A fitting or device so designed and constructed as to provide, when properly vented, a liquid seal which will prevent the back passage of air without materially affecting the flow of sewage or waste water through it.
