Drainage, Waste & Vent第 17 / 120 题
Under the UPC, where does the building drain end and the building sewer begin?
a.At the face of the exterior wall
b.At the property line
c.5 ft outside the building wall
d.2 ft outside the building wall
解析
The UPC sets the boundary between building drain and building sewer at 2 ft outside the building wall, which is where the sewer designation and its materials rules take over. The exterior wall face and the property line are not the code dividing point, and the 5 ft dimension is the boundary used by some other model codes, not the UPC.
