The valve should be closed, but a good way to check is to turn it to the opposite position and run the hot water tap until you get hot water coming out. One way to check the other bypass valve is first drain the hot water tank and leave the plug out. Hook up the city water and turn it on. Rotate the bypass valve in either direction till water comes out the hot water tank drain, this would be the position used for camping or normal use, and of course if you turn the valve in the other position your lines will pressure up and no waterwill be coming out of the hot water tank drain, this would be the winterizing position.
There are many other methods to this process to which others here may sharebut I have found this to be easiest way for me.
