The auto switch regulator only draws from one tank at a time. If you think you will be emptying a tank during any given period of time, you should have both tanks on. The switch will automatically switch off the almost empty tank and switch on the full one. If you keep one tank off, the switch willvnot work when the in use tank is empty. If this is in the middle of the night or when you are away, your propane devices will stop working and be harder to start. If you are using a lot of propane, you can mark the tank you start with and when you notice the switch has switched to the other tank you can fill the empty one.
