How to Fill Small Propane Bottles

Whether it is used to heat water for a home or used as the fuel in a fireplace, propane is used in a variety of different applications that all help improve the quality of everyday life. While many in rural settings are accustomed to seeing near homes large-capacity propane tanks that weigh hundreds and, in some instances, thousands of pounds, smaller, lighter-weight tanks are also available. Fortunately, there are processes for filling these smaller tanks in a safe and effective way.

Instructions

- 1
  Inspect the propane tank to ensure that the cylinder's manufacture date or recertification date is visible. Examine the outside of the tank for defects, placing special emphasis on examining the tank for excessive rust as well as cracks and dents.
- 2
  Ensure that the tank has all of the necessary hardware attached. In addition to an overfill protection device, the tank should have a foot ring, cylinder collar and valve collar in place.
- 3
  Look for the water capacity specifications on the tank. The water capacity can be converted to obtain the number of pounds of propane the tank can hold. A link to a conversion chart is provided in the resources section below.
- 4
  Find the tare weight specification on the outside of the tank. This is the empty weight of the tank.
- 5
  Place the tank on the filling station scale. Connect the filling hose to the top of the propane tank and begin filling the tank. The tank is filled when the scale indicates that the tank's weight is the sum of the tare weight and propane capacity in pounds. In the event that capacity is reached, the bleeder valve will begin to leak fluid.
