Frequently Asked Questions

How do I read my tank gauge?

Your tank gauge is located on the top of the tank, usually under a lid or hood which can be lifted up to view the gauge. Look for a gauge dial with numbers from 5 to 95. The numbers indicate the percentage of propane in the tank. When the level reaches to 30%, please schedule a delivery online or call customer service at (800) 263-7442.

Why isn't my tank filled to 100%? 

For safety, propane containers are only filled to 80% of their capacity. This is called the 80% fill rule. The 80% fill rule is a preventative safety measure against fluctuations that happen inside a tank. Propane, like water, will expand when heat is added to it. Propane, however, will increase in volume nearly 17 times greater than water over the same temperature increase. Filling the tank to only 80% allows for extra space in the tank to allow for this expansion. For more information on propane safety, please visit

What should I do before I dig near my underground propane tank?

In many cases, propane gas lines run underground between your propane storage tank and your house or business. That’s why it is important for you to know exactly where your gas lines are located and to avoid digging in that area.
