Cross-over valve closed, supply lines open. Valves are probably under the bed (Water will be filling the hot water heater)
Low point drain valves closed (I'm not sure where those valves are in your AS but it sounds like the low point valves are still open.)
I don't know about the valves under the sink. If there's 4 they probably do more than feed that sink. Can you upload a picture?
