Gray Water Drain System
•
Gray water (water from sinks and showers) above the waterline is gravity drained overboard, while gray water
below the waterline is drained into a holding tank.
•
When the holding tank reaches a predetermined level, the tank’s float switch automatically activates the sump
pump to empty the tank’s gray water overboard.
•
The shower sump pump can be accessed through the cutout in the hallway at the bottom of the stairs leading to the
stateroom.
