Quick Tip: How to Check How Much Gas is Left in Your Bottles
Not sure how much gas you have left in your 45L bottle? Here is a tip tip on how to check.
Firstly fill a container with warm water (not boiling), then pour slowly over the top of your gas bottle .
You should see a condensation line appear which indicates the level your gas is at, otherwise
slide your hand down the bottle where you poured the water and feel for where the bottle changes temperature turning from hot to cold. This will indicate where the gas level is.
If you do not feel a difference in temperature this may mean your bottle is empty.
