2.2 backflow: The flow of water or other liquids, mixtures, or substances into the distribution pipes of a potable water supply from any sources other than its intended source.
2.3 body waste: Solid waste materials, inclusive of urine and feces, deposited in plumbing fixtures.
2.4 burst protection: Prevention of physical damage to the potable water system by antifreeze at specified protection temperature and concentration of active ingredient.
2.5 corrosion-resistant materials: Materials that maintain their original surface characteristics under prolonged contact with the environment and chemical compounds.
2.6 drainage system: Piping that conveys body or liquid wastes to the drain outlet, excluding the sewer connector.
2.7 fixture: A receptor for water or waterborne wastes that discharges into a sanitary drainage system or waste holding tank.
2.7.1 fixture drain: The drain from a fixture’s trap or the drain outlet, or to the junction of that drain with any other drain pipe.
2.8 flood level: The level in the receptacle over which water would overifow to the outside of the receptacle.
2.9 flush water holding tank: A tank designed to be manually filled with water that is not intended to be plumbed into a potable water distribution system.
2.10 liquid waste: The dischrqe from any fixture, appliance, area, or appurtenance that does not include discharges trom witer closets and urinals.

2.14.1 readily removable: Capable of being taken away from the main unit without using tools.
2.15 self-contained, recirculating, chemically controlled toilets: Toilets with a pump to force flushing liquid (with required chemical) from the self-contained tank through a mechanical, self-cleaning filter into the peripheral rim of the bowl, to flush deposited contaminants back into the tank.
2.16 single fixture pump: A pump to deliver water to a single fixture other than a toilet. Pumps may be manually or automatically activated.
2.17 smooth: Free of pits, pinholes, cracks, crevices, inclusions, rough edges and other surface imperfections detectable by visual and tactile inspection.NSF ANSI 24 pdf download.
