Definitions. Unless the contents specifically indicate
otherwise, the meaning of terms used in this article shall be as follows:
BACKWATER VALVE
A backflow prevention device that shall be installed after
all sewer fixtures in a building along the sanitary sewer lateral
to the public sanitary sewer main. The valve is used to prevent outbound
sewer flows from re-entering the building, as well as to prevent sewer
flows from the public main to overflow fixtures within the building.
The backwater valve shall be installed in circumstances where the
elevation of the upstream manhole is above the sewer fixtures within
the building, to prevent blockage or flow restriction in the main
to back into the building.
