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 gray water in the holding tank reaches a predetermined level, the tank’s float switch automatically turns on
the sump pump to pump the gray water overboard.
• The shower sump pump can be accessed through the cutout in the hallway floor at the bottom of the stairs leading
to the stateroom.
