VENTILATED SANITARY PLUMBING SYSTEMS

摘要

A system for forcibly ventilating a multi-story building connected to a main sewer line (15) includes at least one generally vertical sanitary stack (10) in gaseous communication adjacent the top thereof with atmosphere and adjacent the bottom thereof with a ventilating pipe (16). The ventilating pipe (16) is in gaseous communication with each stack (10) (below the lowermost sanitary inlet to the stack) for receiving the gaseous content from adjacent the bottom thereof. A stack fan (11) in gaseous communication with each stack (10) adjacent the top thereof forcibly and continuously blows air down the stack (10) to the ventilating pipe (16), and a pipe fan (17) in gaseous communication with the ventilating pipe (16) adjacent the exhaust end thereof forcibly and continuously exhausts off the gaseous content of the ventilating pipe (16) to atmosphere at a location remote from the stacks (10).
