Propane Gas Valve

[steveqvs]

So my propane gas valve showed empty this weekend when I knew there was a full tank on there. I took it off and banged it a little bit and then it worked. So is this something i should worry about?

You mean your LP tank switchover valve stuck?
Every mechanical device needs a good whack once in a while.
If it repeats and causes you problems THEN you worry or
get a new one.

Did you have 2 tanks with one empty and one full?

May not be related but I once turned on a known full tank and
found very low pressure.
Could barely get a gas stove burner to light.
Furnace would not stay lit.
Of course it was the middle of the night and we were freezing!!
It turned out to be the safety valve in these @#$%^ new style
LP tanks.
If you turn one of them on too fast, it can cause the "blown hose"
safety to shut off.
Solution is to shut the tank, wait a minute, turn the tank back
on slowly!

Had exactly the same thing happen to my gas grill the other day.
I nearly always turn on the tank, then the burner, then hit the
starter.
On this day for what ever reason, I flipped on the burner and then
spun the tank valve open, then hit the starter.
It lit but after several minutes I realized it just was not getting
as hot as usual.
Solution-- shut off the tank and burner.
Pause--
Open the tank slowly.
Open the burner and re-light.
HOT grill in a minute!!

Hope this helps!!

So if there's no resistance such as a pressure regulator the tank will not allow full flow of propane. Makes sense, never thought or knew about that. Thanks for the info KyDan.
