Propane tanks need to be air-free for safety reasons, but it's sometimes easy to forget the needs of the propane hose. Air bubbles trapped in the propane line can make you suffer a temporary interruption of service. Bleeding the hose removes the excess air from the lines and ensures you will receive a consistent line of propane from the hose. Be careful to protect yourself during the bleeding process, though, or you can cause damage to your property or yourself.

Step 1

Move the propane tank outside so it's in a well-ventilated area. There is a possibility of health problems if you bleed the line indoors.

Step 2

Protect your eyes with goggles and your hands with gloves. Propane is a dangerous gas if you don't handle it properly, so take the time to protect your skin before you begin.

Step 3

Check to make sure the hose is tightly secured to the nozzle on top of the propane tank. Leave the other end of the line free so it can bleed into the atmosphere.


Step 4

Slowly turn on the valve of the propane tank. Wait until you consistently smell propane. The steady stream of propane pushes all the air through the hose and out into the atmosphere.

Step 5

Turn off the hose once all the air is gone from the hose.


Connect your propane line to a grill to burn off the excess propane.


Never introduce propane to an open flame that the propane is not regulating. For example, extinguish all cigarettes around the propane line even if it’s operating a grill.
