Here is the type of auto switch over I have between the two tank on my trailer.I've not witnessed it actually switch between tanks. When it does, does it phisically turn the knob and point at the operable tank?How does the little red or green indicator change...if it does.First RV I've had with dual tanks.....Thanks for any comments

Nevermind...I think I figured it out.....The center sight glass is the indicator. If it is "green", I'm drawing from whatever tank the green indicator is adjacent to. If the sight glass is "red"...I'm drawing from whatever tank the red indicator is adjacent to.Correct?

It doesn't switch between tanks. whatever tank you have open and are using you have it on green. When it runs out you flip the knob so that the empty tank is red and the new tank is green. its entirely pointless if you have both tanks turned on. It's just a visual. I wish it was smart enough to regulate and switch between tanks, etc. Its not.

This video says it is "automatic"....When one tank runs out, it automatically switches to the other tank.....No??https://www.youtube.com/watch?v=MjqE00P2aPY

I wish it was smart enough to regulate and switch between tanks, etc. Its not.That looks to be a Mr. Heater brand auto valve, and it will switch its input from empty tank to full tank automatically if it is working properly. Assuming you start with both tanks full and both valves open, the regulator will draw from the tank to which the valve handle points until that tank is empty. Then it will switch to the remaining tank and the indicator will change from green to red indicating that the first tank is empty. At that time you switch the valve handle toward the full tank, and fill the empty one.

We will call the tanks L and R. You open both tanks. You want to draw from the L tank. You put the needle(arrow pointer) towards the L tank. When the L tank runs out, the pressure differential causes the changeover valve to open to the R tank. At this point, the GREEN indicator will go the RED. That is YOUR visual indicator that the L tank is empty and it has Auto changed to the R tank. You then take the manual needle/pointer arrow and turn it to the R tank. You can now disconnect the L tank from the pigtail to get it refilled without having an LP leak. If you do NOT turn the pointer to the full tank, you may have a LP leak out of that hose. Most RV'ers always use 1 particular tank first so they always know which tank is drawing from first every time. Doug
