Filling potable water tank? SOLVED

New to me Coachman (See signature) and I can't find how to tell when the tank is full. Yes I know about the inside gauge that shows levels of all tanks but when outside how do I know when to turn off the water as I don't want to burst a pipe inside?
Also how do I know the water heater is full when I have the bypass in the correct position for getting hot water?
I've been RV'ing half my life but this is the first time I've had a CLOSED system. All others had an overflow. Nothing in the Coachman book about it. Do I crack the sink faucets?
Thanks for understanding.

    When more water is spraying out of the fill tube than is going in the tank, it's full. Don't worry, pipes won't burst.

    Open a hw valve in a sink and wait. Pretty much same way as at home, if you have one.
