Where to take your propane tank and what to expect
You can refill a propane tank at most gas stations, hardware stores, and propane dealers. The process takes 10 to 15 minutes once you arrive. You'll hand the attendant your tank, they'll connect it to a filling machine, and you'll pay by weight — typically $2 to $4 per pound, though prices vary by location and current propane costs.
Before you go, check that your tank has a current safety inspection sticker. Propane tanks must be inspected every 12 years; if yours is older or has no sticker, the station will refuse to fill it. You can find the inspection date stamped on the collar of the tank itself.
Call ahead if you're unsure whether a particular location fills propane tanks. Some stations fill only their own branded tanks, while others accept any tank. Having a phone number saves a wasted trip.
Key Takeaways
- Propane tanks must have a current safety inspection sticker (valid within 12 years) or the station will not fill them.
- Most gas stations, hardware stores, and propane dealers offer refills, but you should call first to confirm they accept your tank type.
- Filling takes 10 to 15 minutes and costs $2 to $4 per pound, depending on your location and current propane prices.
- Bring your tank to the station; the attendant handles the connection and filling process.
- Never attempt to fill a propane tank yourself — it requires specialized equipment and creates a serious safety hazard.
Preparing your tank before you leave home
Check the valve at the top of the tank. It should turn freely and not leak. If you hear a hissing sound or smell rotten eggs (the odor added to propane), do not take the tank anywhere — that indicates a leak. Contact the propane dealer or a local hazmat team instead.
Look at the collar of the tank for the inspection date. The date is stamped as a month and year. If the tank was last inspected more than 12 years ago, or if there is no date visible, the station will turn you away. In that case, you'll need to replace the tank rather than refill it.
Transport the tank upright in your vehicle. Lay it on its side only if you're moving it a short distance to a refill station. Never transport a propane tank in a closed trunk or passenger cabin — always place it in an open truck bed or the back of an open trailer.
What happens at the refill station
Walk into the station with your tank and tell the attendant you need a refill. They'll inspect the valve and collar for the safety sticker. If everything checks out, they'll take the tank to the filling area.
The attendant connects your tank to a large propane dispenser using a special coupling. The machine measures the weight of propane flowing in and stops automatically when the tank reaches capacity. This process is fully automated — you won't see flames or hear loud noises, just the sound of the machine running.
While your tank is being filled, stay in the station or in your vehicle. Do not stand directly over or next to the tank during filling. Once the machine stops, the attendant disconnects your tank, checks the valve one more time, and brings it back to you.
Paying and understanding the cost
Propane is sold by the pound. A typical residential tank holds 20 pounds when full. The price per pound varies by region and changes with market conditions — it can range from $2 to $4 per pound or more. A full 20-pound tank might cost $40 to $80, but this varies significantly.
Some stations charge a flat fee for refilling instead of charging by weight. Ask the attendant which method they use before handing over your tank. A few stations also offer loyalty discounts or lower prices if you bring your own tank rather than exchanging an empty one for a full one.
Pay at the counter after the tank is filled. Most stations accept cash and card. Ask for a receipt — it shows the weight of propane added and the price per pound, which is useful if you want to compare costs across locations.
Signs your tank needs replacement instead of refilling
If the inspection date on the collar is more than 12 years old, the tank cannot be refilled. You'll need to buy a new one. A new 20-pound propane tank costs $30 to $60, depending on the brand and where you buy it.
If the valve is damaged, cracked, or leaks, the station will refuse to fill it. A damaged valve is a safety issue and cannot be repaired on a consumer tank — replacement is the only option.
If the tank body is visibly rusted, dented, or punctured, do not attempt to refill it. Bring it to a propane dealer or hazmat facility for disposal. Many dealers will take an old tank for free or a small fee when you buy a replacement.
What to do if the station won't fill your tank
The most common reason a station refuses a refill is an expired or missing inspection sticker. If this happens, you have two choices: buy a new tank, or find a propane dealer who can re-inspect your existing tank. Re-inspection costs $15 to $30 and extends the tank's life for another 12 years.
If the valve is the problem, replacement is necessary. Some propane dealers can replace a valve, but it's often cheaper to buy a new tank outright. Call a few dealers in your area to compare prices before deciding.
If a station says they don't accept your tank brand, try another location. Most independent propane dealers and many gas stations accept any tank that passes inspection. Chain hardware stores sometimes have stricter policies, so a local propane supplier is often your best bet.
Storing your filled tank safely at home
Keep the tank upright in a well-ventilated outdoor area, away from direct sunlight and heat sources. Never store it in a garage, basement, or enclosed shed. Propane is heavier than air and can accumulate in low spaces, creating a fire or explosion hazard.
Store the tank at least 10 feet away from windows and doors to your home. If there's a leak, distance reduces the risk of propane entering the building. Keep it away from grills, heaters, and anything that produces a flame.
Check the valve occasionally for leaks. If you smell rotten eggs near the tank, turn off the valve when ready, move everyone outside, and call your propane dealer or the fire department. Do not re-enter the area until a professional has cleared it.
Frequently Asked Questions
Can I refill a propane tank that's still partially full?
Yes. The attendant will connect your tank to the filling machine, and it will fill to capacity regardless of how much propane is already inside. You pay only for the weight of propane added, so a partial refill costs less than a full one.
What if I don't know when my tank was last inspected?
Look at the collar of the tank — the inspection date is stamped there. If you can't find a date or the date is unclear, take the tank to a propane dealer and ask them to check it. They can tell you whether it's still within the 12-year window.
Do I need to do anything special if I'm refilling a tank for the first time?
No. Bring the tank to the station, show the attendant the inspection sticker, and let them handle the rest. The process is the same whether it's your first refill or your tenth. Just make sure the valve works and there are no visible leaks.
Can I exchange an empty tank for a full one instead of refilling?
Yes, many stations offer tank exchanges. You leave your empty tank and take home a full one, usually for a flat fee of $15 to $25. This is faster than waiting for a refill, but you don't own the replacement tank — you're renting it. Refilling your own tank is cheaper over time if you use propane regularly.
What should I do if propane leaks from the valve during transport?
Pull over in a safe location away from buildings and traffic. Do not smoke or use your phone near the tank. Open all windows and doors to your vehicle. Call the propane dealer or fire department from a safe distance and wait for instructions before moving the tank again.
