Propane tanks, both large and small, play a vital role in powering various appliances, from grills to heaters. However, when your small propane tank runs dry, it can be inconvenient to replace it, not to mention costly. So, how to fill small propane tank from a large tank?
To fill a small propane tank from a large one, you’ll need a propane transfer hose. Attach one end to the valve on the large tank and the other to the small tank. Open the valve on the large tank fully and the valve on the small tank slightly. Allow propane to transfer, monitoring it if necessary. Close both valves when done, check for leaks, and store the tanks safely. Always prioritize safety when handling propane.
Read on for everything that you need to know about filling a small propane tank from a large tank.
Understanding Propane Tanks
Before we dive into the refilling process, let’s briefly explore propane tanks’ basic principles and components:
- Large Propane Tanks: These are typically used for home heating, powering generators, or serving as the primary source for multiple appliances. They are commonly found in various sizes, including 100-pound and 500-gallon tanks.
- Small Propane Tanks: Also known as cylinders, these are often used for grills, portable stoves, and camping equipment. They come in various sizes, such as 20-pound and 1-pound cylinders.
Safety First
Safety should always be your top priority when working with propane. Here are some essential safety precautions:
- Work in a Well-Ventilated Area: Ensure you’re outdoors or in an area with proper ventilation to prevent the buildup of propane fumes.
- No Smoking or Open Flames: Keep all sources of ignition far away from the refilling area.
- Wear Protective Gear: Safety glasses and gloves are a must.
- Inspect Tanks: Ensure both the large and small tanks are in good condition with no visible damage or rust.
Tools You’ll Need
Before you begin, gather the necessary tools and materials:
- Large Propane Tank: This will serve as your source for refilling.
- Small Propane Tank: The one you want to refill.
- Propane Transfer Hose: You can find this at most hardware stores or online.
- Wrench or Adjustable Pliers: For securely attaching the transfer hose.
- Propane Tank Scale: Optional but helpful for determining how much propane you’re transferring.
The Refilling Process
Follow these steps to safely fill your small propane tank from a larger one:
- Set Up Your Work Area
Choose a well-ventilated outdoor location and ensure you have ample space to work. Keep all ignition sources away from the area.
- Attach the Transfer Hose
Connect one end of the transfer hose to the valve on your large propane tank and the other end to the small tank. Use a wrench or adjustable pliers to ensure a snug fit.
- Turn on the Valves
Open the valve on the large tank fully. On the small tank, open the valve just a crack—enough to allow propane to flow but not too wide to prevent a rapid transfer.
- Monitor the Transfer
You can use a propane tank scale to keep an eye on how much propane is transferring. Be patient; it may take some time.
- Close Valves and Disconnect
Once the small tank is full or reaches your desired level, close the valves on both tanks. Carefully disconnect the transfer hose, ensuring no propane escapes.
- Test for Leaks
Before using the refilled small tank, conduct a leak test. Apply a soapy water solution to the valve and connections. If you see bubbles, there’s a leak. Tighten the connections and retest.
- Store Safely
Store both the small and large propane tanks in an upright position, in a cool, well-ventilated place, away from direct sunlight and heat sources.

How do you fill a 1lb propane tank from a 20lb tank?
Filling a 1lb propane tank from a 20lb tank can be done using a propane tank refill adapter. Here are the steps:
- Safety First: Ensure you’re in a well-ventilated outdoor area, away from open flames or sparks. Wear gloves and safety goggles.
- Check Valves: Make sure both the 20lb tank and the 1lb tank have their valves closed.
- Attach the Adapter: Connect the propane tank refill adapter to the valve on the 20lb tank. Ensure it’s securely fastened.
- Connect the 1lb Tank: Screw the 1lb tank onto the other end of the adapter.
- Invert the Tanks: Carefully turn the 20lb tank upside down, keeping the 1lb tank on a higher surface. This allows the propane to flow properly.
- Open Valves: Slowly open the valve on the 20lb tank first. Then, slightly open the valve on the 1lb tank.
- Fill the 1lb Tank: Propane will flow from the larger tank into the smaller one. It may take a few minutes to fill completely.
- Close Valves: Once the 1lb tank is full (you can tell by the sound of the gas changing), close both valves.
- Disconnect Tanks: Remove the 1lb tank from the adapter, ensuring it’s securely closed.
- Test for Leaks: Apply a soapy water solution to the valve connections to check for any gas leaks. Bubbles will appear if there’s a leak.
- Store Safely: Store both tanks upright and in a cool, dry place.
Always follow safety guidelines when working with propane, and be aware of any local regulations regarding propane tank refilling.
How do you use a propane refill adapter?
Using a propane refill adapter allows you to transfer propane from a larger tank to a smaller one. Here’s how to use it:
Safety First: Always prioritize safety when handling propane. Work in a well-ventilated outdoor area, away from open flames or sparks. Wear gloves and safety goggles.
Check Valves: Ensure that both the larger propane tank (source) and the smaller tank (target) have their valves closed.
Attach the Adapter: Connect the propane refill adapter to the valve on the larger propane tank. Ensure it’s securely fastened.
Connect the Smaller Tank: Screw the smaller tank onto the other end of the adapter. Make sure it’s tightly connected.
Invert the Tanks: Carefully turn the larger tank upside down while keeping the smaller tank on a higher surface. This position allows the propane to flow properly from the larger tank to the smaller one.
Open the Valves: Slowly open the valve on the larger tank first, allowing propane to flow into the smaller tank. Then, slightly open the valve on the smaller tank.
Fill the Smaller Tank: Propane will flow from the larger tank into the smaller one. Be patient; it may take several minutes to fill completely.
Close the Valves: Once the smaller tank is full, close both valves on the larger and smaller tanks.
Disconnect the Tanks: Remove the smaller tank from the adapter, ensuring that its valve is securely closed.
Check for Leaks: To ensure safety, apply a soapy water solution to the valve connections on both tanks. If you see bubbles forming, there may be a gas leak, and you should address it immediately.
Store Safely: Store both tanks upright in a cool, dry place, away from direct sunlight or heat sources.
Remember to follow safety guidelines and any local regulations regarding propane handling and refilling.
