Refilling 1 lb propane tanks is a common practice for those who use them frequently for camping, grilling, or other outdoor activities. However, it’s essential to do so safely and legally. Here’s a guide to help you refill your 1 lb propane tanks: It is recommended that you not refill the tanks. There are refillable 1 lb tanks available from Flame King. May be available at Cosco.
Things You Need
- Refillable 1 lb Propane Tanks: Ensure your tanks are designed for refilling. Some tanks are marked as “refillable.”
- 20 lb Propane Tank: A standard larger propane tank to transfer propane from.
- Propane Refill Adapter: This connects the 20 lb tank to the 1 lb tank. These adapters are widely available online or at hardware stores.
- Protective Gear: Use gloves and safety goggles to protect yourself from accidental leaks.
Steps to Refill
- Check Tank Conditions:
- Inspect the 1 lb tank for any visible damage or rust. Do not refill damaged tanks.
- Ensure both the 1 lb and 20 lb tanks are empty and in good condition.
- Cool the 1 lb Tank:
- Place the 1 lb tank in a freezer for about 30 minutes before refilling. This reduces pressure inside the tank, making it easier to transfer propane.
- Set Up the Adapter:
- Attach the propane refill adapter to the 20 lb propane tank’s valve.
- Ensure the connection is secure but not overly tightened.
- Connect the 1 lb Tank:
- Screw the 1 lb tank upside down onto the adapter.
- Make sure it is tightly secured to prevent leaks.
- Turn the Larger Tank Upside Down:
- Propane is a liquid when under pressure. By flipping the larger tank upside down, you allow the liquid propane to flow into the smaller tank.
- Open the Valve:
- Slowly open the valve on the 20 lb propane tank. You will hear propane transferring into the 1 lb tank.
- Monitor the Filling Process:
- Allow about 1–2 minutes for the propane to transfer. The 1 lb tank will not fill completely for safety reasons (it will be approximately 80% full).
- Close the Valve:
- Once filled, close the valve on the 20 lb tank.
- Remove and Check for Leaks:
- Carefully unscrew the 1 lb tank from the adapter.
- Apply soapy water to the valve area of the 1 lb tank to check for leaks. If bubbles appear, the tank may be leaking and should not be used.
- Store Safely:
- Store the refilled 1 lb tank upright in a cool, ventilated area away from direct sunlight or open flames.
Important Safety Tips
- Legal Restrictions: Check local laws and regulations. In some areas, refilling disposable propane tanks may be prohibited.
- Avoid Overfilling: Do not attempt to overfill the tank. This can result in dangerous pressure buildup.
- Use Outdoors: Always refill and store propane tanks in a well-ventilated area.
- Inspect Tanks Regularly: Discard tanks that are damaged, rusted, or over 12 years old.
