For Vacuum Breaker we have a term and definition in Plumbing.

An anti-siphon device which prevents the backflow of non potable water into the water supply system. For example, if a handshower were left extended into a bathtub of dirty water, and a siphon effect were to occur, a vacuum breaker would prevent the tub water from traveling back into the water supply system.
