What You'll Learn

Check the seal for cracks, breaks or missing pieces
Checking the seal for cracks, breaks or missing pieces is an important part of maintaining your fuel tank. Seals can become damaged over time, and if left unchecked, this can lead to leaks. It is recommended that you check the seal on your propane tank every time you change or reinstall it. Before fitting the regulator back on, carefully inspect the seal for any signs of damage. Look out for cracks, breaks or missing pieces. If the seal is damaged, it may need to be replaced.
You should also perform a leak test after checking the seal. This will help you identify any potential issues with your fuel tank. If you notice any leaks, it is important to address them as soon as possible. Leaks can be dangerous and can cause damage to your property or the environment.
In addition to checking the seal, it is important to regularly inspect your fuel tank for other signs of damage or wear and tear. This includes checking for oil leaks, clogs in the vent pipes, and unprotected oil lines. If you notice any issues, have your tank serviced or inspected by a licensed technician.
It is also worth noting that propane tanks have an expiration date, which is typically between 10 and 12 years from the date of manufacture. Depending on the legislation where you live, tanks may be re-qualified by licensed professionals, adding about five years to their lifespan.

Perform a leak test
To perform a leak test, you should check your propane tank regularly for signs of damage. If your pilot light is struggling to stay lit or keeps going out, this could indicate a problem with your propane tank. You should also check for stray oil around the tank, particularly around the gauge or on the ground underneath, as this could indicate a leak. If the rubber tubing that carries oil between the tank and the furnace is split or cracked, have the unit serviced immediately. You can also check the expiration date on your propane tank, which is usually between 10 and 12 years from the date of manufacture.

Check the expiration date
Checking the expiration date is a crucial step in determining whether you need a replacement fuel tank. Propane tanks, for instance, typically have an expiration date between 10 and 12 years from the date of manufacture, which can be found on the handle of the tank near the tare weight. This date is subject to the legislations of your place of residence.
To ensure your safety and maintain the functionality of your propane tank, it is essential to be mindful of this expiration date. While tanks can be re-qualified by licensed professionals to extend their lifespan, this process typically adds only about five years before another re-qualification is required. Therefore, keeping track of the expiration date and planning for a replacement tank before the end of its lifespan is highly recommended.
Additionally, regular inspections of your propane tank are necessary to identify any signs of damage or malfunction. A well-functioning propane tank should consistently supply an adequate amount of fuel to your furnace's pilot light. If you observe that the pilot light struggles to stay lit or frequently goes out, it could indicate a problem with your propane tank.
By paying attention to the expiration date, staying vigilant about regular inspections, and addressing any issues promptly, you can ensure the safe and efficient use of your fuel tank until it's time for a replacement.

Check for oil leaks
Checking for oil leaks is an important part of maintaining your fuel tank. Here are some steps you can take to check for oil leaks and determine if you need a replacement fuel tank:

Secondly, examine the oil lines that connect the tank to the furnace. Look for any splits or cracks in the rubber tubing. If you notice any damage, it is important to have the unit serviced immediately to prevent further issues.
