How to Check Your Propane Tank Level

The three most common ways to check the propane level in a tank is by checking the gauge (if available), the weighing method, and the warm water method. 

Many larger propane tanks have a built-in gauge. This is the most accurate way to determine how much propane is left in the tank. If the gauge is in the red zone, it's time to refill the tank.

The Weighing Method

Most propane tanks have a tare weight (weight of the empty tank) stamped on the collar. You can weigh the tank on a scale and subtract the tare weight to estimate how much propane is left.

For example, if a tank weighs 40 pounds and the tare weight is 18 pounds, then there is about 22 pounds of propane remaining (40 lbs - 18 lbs = 22 lbs).

Keep in mind this is an estimate, and the weight of the propane can vary slightly depending on temperature.

The Warm Water Method 

While less accurate than weighing or reading a gauge, this is a simple trick that will show you how much propane is left in the tank. 

Pour warm water down the side of the propane tank. The liquid propane inside the tank will absorb heat from the water, so the tank will feel cool where there is propane and warm where it's empty.

Additional Tips

  • Safety first! Never use an open flame to check the propane level in your tank.
  • Consider installing an external propane tank gauge if your tank doesn't have one. These are available at most hardware stores.
  • Keep track of how long you typically use your propane tank for a particular appliance (grill, heater, etc.) This will help you anticipate when you might need a refill.
  • It's always better to err on the side of caution and refill your tank when it's getting low. Running out of propane in the middle of winter or while cooking can be inconvenient and frustrating.
