Propane system question/regulator

That's interesting, because I was told a little differently (but kinda the same?). Point the indicator lever towards one tank - it will use that tank until it is empty, the indicator thingy will go to red, and the inside valve will automatically switch to the second tank... without a person having to move that lever. That way you still have propane, but you know you have to fill up one of the tanks.

It would seem you and others are not understanding how an automatic changeover gas regulator is designed to work. First, that indicator lever you set yourself according to which one of the two tanks you're using at the time. If you want to use the tanks sequentially you would only open the valve on the in-use tank, not both tanks, and point the lever to this tank as a reminder that that's the tank you're currently using. If on the other hand you prefer to use both tanks you would open both valves which in turn will allow the auto changeover regulator to automatically switch over from the first tank once it empties to the full second tank. The obvious disadvantage is that both tanks will eventually empty and and if you don't keep an eye on the indicator you'll end up with no gas at all. That's why my own personal preference is to open just one tank valve at a time and run the tanks sequentially, as once my in-use tank empties I can then manually switch over to the spare tank, making it the new in-use tank. That process reminds me to refill the original but now empty in-use tank and once reinstalled on the trailer it becomes the new spare tank. I've even marked my two tanks "Curb" and "Street" as a reminder where each tank normally lives.

Edited for clarity ... shouldn't write this stuff when I'm in a hurry! :W
