Diameter = The length along the center of the pipe and fitting Developed Length = The nominal internal diameter (ID) of a pipe, except brass and copper tube where the term refers to the outside diameter (OD) Effective Opening = The minimum cross-sectional area at the point of water supply discharge, measured or expressed in terms of diameter of a circle Drainage System = All piping within the public or private premises that conveys sewage, rainwater, or other liquid waste, to a legal point of disposal

Existing Work = The portion of a plumbing system that has been installed and approved prior to the contemplated addition, alteration or correction Drainage System = A pipe connecting several fixtures Dry Vent = The extended portion of a pipe that is closed at one end permitting the stagnation of water or air therein Fixture Branch = All piping within the public or private premises that conveys sewage, rainwater, or other liquid waste, to a legal point of disposal
