to overflow the top or rim of the fixture.

means of disposal.
A metal duct through which vapors of foul air are removed from room
or fixtures.
The same as a circuit vent except that it loops back and connects
with the soil, waste or stack vent instead of the vent stack by means of which
siphonage and back pressure on the seals of traps are prevented by running
two separate ventilating pipes, the fixtures being placed between two such
pipes and the loop or yoke vent pipe being carried over fixtures back to the
main vent. This system can be used on only one floor.
The main of any system of continuous piping is the principal artery
of the system on which branches may be connected.
The main sewer or public sewer in the street, alley or other premises
