Abstract
A ventilating system includes a manifold connected to the interior of a toilet bowl, and a system for continuously moving air from that toilet bowl to a discharge system. A flow control valve prevents water from moving through the system and includes a cage containing a ball both of which are oriented nearly horizontally with the valve preventing water that is inadvertently located in the air flow path from moving through the discharge system, and a solar energy-driven expansion chamber is connected to the discharge conduit to establish a flow producing pressure gradient throughout the system.
