The tank would have to have a lower pressure inside for air to enter.
That aint gonna happen.

It does if you leave the valve open!


Maybe old tanks. The new ones have a valve that must be pushed open like
the tire valve on your car.



You can see how well that works!

Ya gotta close the valve, dude. Otherwise, you can get air and
moisture in the tank. That valve you are talking about is not intended
to be the main shutoff, and it seals better in one direction that the
other. That's why there is that big 'ole knob for you to turn on top.
They aren't going to do an autopsy first to see if each individual
tank actually has any moisture in it. If you come to get an empty tank
filled with the valve wide open, you lose. Zip up your fly and tie
your shoes while you're at it.

Sheesh.

diabetes, high blood pressure, heart disease, emphysema, male pattern
