Question 7 • SVHS Building Construction ##FA

Based on the passage below, where is the main outlet of a vent stack most likely located in a house? A crucial component of the drain-waste-vent system is the vent stack, which carries away harmful sewer gases and allows drains and toilets to function smoothly by removing the vacuum behind the flushed waste.

Answer
A
the roof
B
the kitchen
C
the basement
D
the bathroom

Explanation

A vent stack carries sewer gases out of the house, so its outlet needs to release them outdoors. It is most likely located on the roof, rather than inside a kitchen, basement, or bathroom; the correct choice is the roof.
