Left Grill Knobs ON and LP Tank Valve OFF-Why did it mess up the tank where valve screws in?
Scenario: I left the KNOBS on my gas grill in the ON position. I turned OFF the VALVE on top of the propane tank.
Now when I turn propane tank to ON via the valve on top of it, it spews hissing gas out through the area where the valve screws into the top of the LP tank. It is coming out around the actual threads of that screw in valve.
Someone please explain what might have happened. Thanks.
(I am going to swap out the tank at the store where I got it, hopefully for free cause it was darn near full, but I am just very curious about what happened.)

The 2 parts to the question are unrelated. The valve on the top of the tank will allow gas to flow to the grill when open. The burner valves allow the gas to continue on to the burner(s) when open. All the valves do is let the gas go by when open. When you replace the tank YOU are making the connection from the tank to the hose which feeds the grille. If gas leaks from that connection you have incorrectly made the connection. It's likely you have improperly aligned the two pieces and believed that the connection was tight when it actually could not go any farther. The grille instructions should say to check for leaks after changing the tank. You can do this by mixing dish soap and water and applying with a brush or rag on the fittings with the valve open and the burners closed. If there is a leak you will see bubbles form. Then close the tank and fix the connection. If you get stuck take pictures with your phone and show your propane people and they should be able to guide you. PROPANE IS AN EXPLOSIVE GAS. Keep the tank valve closed (turned clockwise all the way down) when not in use and if you're not sure what you are doing, DON'T!

What happens if you open a propane tank valve?
The bottle feels heavier and obviously is filled with propane but opening the valve produces no escaping gas. OPD valves are designed so that propane will not flow from the service valve unless it is hooked up to a hose end connection. This is the way the OPD cylinder valve was designed.Why does my propane tank lock up?
Sometimes excessive sunlight (overheating) will also cause a LOCK OUT \u2013 too much sunlight causes the propane to heat up and build excess pressure. A leak or another tank issue will cause a LOCK OUT.How do you reset a propane tank valve?
You should open a propane tank valve all the way when using a grill. The valves are double sealing which means they seal in a fully open or closed position. Turning it partially increases the chances of gas leaking. Turn the valve counterclockwise (in the \u201cOpen\u201d arrow direction) until it stops.Remove Propane Tank Valve in 1 Minutes (No Special Tools)
