I have two propane tanks connected through a changeover valve (picture attached). I close the tank I'm not using.
The left-side propane tank ran out last night, and so I opened the right-side tank (picture attached) and used a couple gallons keeping the rv warm overnight.
I then went out and filled both tanks, but when I re-mounted the tanks and opened the left-side tank, the right-side (as in the other side of the changeover) tank regulator's vent hole hissed out lots of propane.
With both tanks open, the right-side regulator hisses and leaks from the vent, same as if only the left-side is open. However, when the left-side is closed and the right-side is open, it doesn't hiss and is at least apparently not leaking. What is going on?
Is it that the changeover valve is broken because it shouldn't be letting left-side gas go to the right side, and the right-side regulator is bleeding out any pressure that is back-flowing? But isn't the hose pressurized as it is when appliances are off and so the regulator should handle back-flow? Or maybe it can't handle back-flow at unregulated pressure from the other side? But it was working fine before refilling the tanks.
Or is it that the right-side regulator suddenly failed? But it seems to not be leaking when the right-side tank is open (left-side closed) and appliances are using it.
Or is it that I somehow messed up while re-attaching the connections? I'm not sure how. And the right-side regulator also hisses and leaks even when the whole hose isn't attached to the right-side tank.
Does anyone have experience with this kind of problem?
