| Tank Part | Description and Function |
| Liquid Withdrawal Valve | A tube that dips into the liquid propane.
Used to empty the tank before service or transportation or to refill a portable propane tank. |

If the tank becomes too pressurized, the return valve will open to release the gas or direct the propane back into another storage container. |
| Float Gauge | A device that floats atop the liquid propane and measures the approximate percentage filling the tank. |
| Fixed Level Liquid Gauge | A tube that helps propane delivery personnel know when the tank has reached its maximum fill. |
| Service Valve | The part of the tank that allows propane to flow into a home’s pipes as fuel.
You can shut off this valve in the event of a leak or emergency. |
| Safety Relief Valve | A spring-like device that keeps the tank from building up excess pressure.
Opens up under high pressure to prevent the tank from bursting. |
| Fill Valve | A hose fitting that delivery personnel use to fill up the propane tank.
Fill valves have gaskets and caps to prevent debris from entering the tank and gas escaping. |
Before jumping into size options for your propane tank, note that tanks can only hold 80% of their capacity.
For example, a 2,000-gallon tank holds 1,600 gallons when full.
Propane liquid expands as the temperature increases, so this design feature allows for swelling and prevents the tank from bursting. You’ll encounter the 80% rule no matter what size tank you select.
