How to Transfer Propane From an Old Tank to a New Tank

Learn how to transfer propane to a new tank.

Propane is a fuel that is used for outdoor gas-powered grills, most commonly stored in tanks. Most home improvement stores provide refills of propane tanks, but when this service is not available, you might have to perform the transfer yourself. Learn how to transfer propane from one tank to another using just a transfer hose and two propane tanks.

Things You'll Need

• POL to POL jumper hose
• Empty propane tank

Instructions

1. Find a well-ventilated space outside to perform the transfer. Make sure that the jumper hose that you are using is specified for liquid propane use. Attach the hose to both propane tanks, ensuring that it is securely screwed on. Make sure that the receiving propane tank is completely empty.

2. Turn the feeder tank upside down and set it at a higher point than the receiving tank. Make sure that it is secured and will not fall.

3. Open the receiving tank´s valve and then open the feeder tank´s valve. Create a difference in temperature between the two tanks. The receiving tank´s temperature must be colder than the feeder tank´s. The best way to achieve this is to put the feeder tank in the sun while keeping the receiving tank in the shade.

4. Stop the transfer when the receiving tank is 80% full. Most American-made propane tanks will automatically stop the transfer at this point.

Tips & Warnings

• Make sure that the propane tanks are of the same size and propane capacity.

• Use extreme caution, as propane is highly dangerous. Only use a liquid propane-specific hose for the transfer.

• Make sure that there are no leaks in your feeder propane tank.
