DECK FILL
A flush-mounted deck fill fitting is located on the port walkway aft of frame 25. The deck fill allows the potable water tank
to be filled from an external source of treated water.
VENT
An inverted check valve vent is located on the starboard walkway aft of frame 25. The vent provides ventilation to the tank
as the tank level changes. The inverted check valve opening is protected by a screen to keep insects and other contaminants
from entering the system.
TANK MONITOR SYSTEM
A remote tank level monitoring system is installed to allow tank level monitoring from the pilothouse. The tank monitor
system consists of a float switch mounted in the potable water tank and a control panel in the pilothouse console. The float
switch is actually made up of three microfloat switches, one for each liquid level (empty, mid, full) assembled as a single
unit. When the liquid is at or above the level of a microfloat switch, a signal is sent to the control console in the pilothouse.
On the control console, a red Light Emitting Diode (LED) is lit when the tank is empty, an amber LED is lit when it is at the mid
point, and a green LED is lit when it is full. The system is powered by the vessel's 24 Vdc electrical system through the control
and distribution panel in the pilothouse.
