The GWIV's function is which of the following?

• A. It seals off the gray water line
• B. It automatically vacuums out the sink when near full
• C. It diverts gray water to the potable water tank
• D. It monitors gray water levels only

Answer: (D)

The GWIV is a device in the gray water system whose job is to monitor the level of gray water. It does not seal lines, vacuum out the sink, or divert gray water to the potable water system. Those tasks are handled by other components such as isolation valves, pumps, and separate diversion paths. By providing level information to the system controls, the GWIV helps ensure the gray water tank is not overfilled and that pumps or alarms operate at the right times. So the function described—monitoring gray water levels—is the correct one.
