air gap - CORRECT ANSWERS Air space used to separate a water supply outlet from any
potentially contaminated source; for example, the air space between a floor drain and the
drainpipe of a sink.
backflow - CORRECT ANSWERS Unwanted reverse flow of contaminants through a
cross-connection into a drinkable-water system.
backsiphonage - CORRECT ANSWERS A backflow that occurs when high water use in
one area of an operation creates a vacuum that sucks contaminants into the drinkable water
supply.
booster heater - CORRECT ANSWERS Water heated attached to hot-water lines leading
to dishwashing machines or skins, Raises water to the temperature required for the heat
sanitizing of table ware and utensils.
coving - CORRECT ANSWERS Curved, sealed edge placed between the floor and wall to
