For aircraft Potable Water Systems, how do we determine the water level of the potable water tanks?
There is no way to check the potable water tank levels in the CRJ 700
A sight gauge located below each lavatory sink basin shows the water tank level
Indicator lights (5 LED per system) indicate the tank quantities when the system switches are on

A drain mast fault has occurred
The potable water service panel selector is in the drain position
This is a normal indication on the ground with full potable water tanks
None of the above
A drain mast fault has occurred

The forward and aft potable water systems are independent except:
A common control panel located in the galley
The pressurization source from a common air supply or compressor
They are serviced from a single servicing panel on the right side of the fuselage
Both A and B
The pressurization source from a common air supply or compressor
