Automatic switch over on propane tanks

msgtearley

I have 2 30 pound tanks, both are full. when the one on the right runs out and I try to switch over to the one on the left, I can not get any propane to flow. It is just like the tank on the left is empty, which it is not. I have taken the tank from the left and put it on the right and it works fine. I just am not sure what is preventing the propane from flowing from the left. A regulator is hooked up to the tank on the left and then it goes to the switch over valve. Any ideas on how I can check out the regulator and the switch over valve?

If I turn the valve to left tank, it feeds from the left tank. If I turn the valve to right tank, it feeds from the right tank. When one tank runs out it switches automatically, but I then turn it to the tank that is feeding so I can remove the empty tank. Sounds like control.

I like it when there's a problem and solution, maybe he'll come back sometime and report his finding!

The EASIEST solution is to stop by your propane dealer (any propane dealer) tell him what is going on and in a few minutes he will diagnose your problem, and likely offer to fix it for you, at a rate probably lower than any place else you will find. And the job will be done CORRECTLY.

Should be a lever to designate the primary tank.
And yes the secondary bottle should feed the RV with no adjustment.

My auto switchover regulator failed a few weeks back. A new one solved the problem.

Every time I turn my tanks on, VERY slowly, I can't get gas. I have to lightly tap the regulator with a wrench and that does the trick. Think I should go ahead and replace the regulator?

I sure like my FW, where the 2 propane tanks are side x side with a single valve T'd between them.

Your RED regulator is bad. They reduce cylinder pressure down to 30# and then feed across rig to other side and main regulator.
Is it time for your medication or mine?

The safety valve on the affected tank is likely stuck in the closed position. Disconnect the pigtail hose, be sure the tank valve is turned OFF. Insert a small flat screwdriver in the opening against the valve seat and give it a quick rap with the palm of your hand. Be sure the valve is OFF before you try this. You should hear a quick short hiss. Reconnect your pigtail and open the tank valve SLOWLY. It should work as normal.
