They grew popularity because the idea of having a massive oil tank out of sight was very appealing. However, as the years went on, some of them started to leak. They became environmental hazards and by the 90s, had begun removing these tanks.

It’s very rare to see any home built since the 1980s to still have underground tanks. If you’re curious, check to see if you have two pipes sticking out from underground. If you see those two pipes, you likely have a buried tank.

You should replace your underground oil tank as soon as possible. This is because, even if it hasn’t start leaking, it will eventually. An underground oil tank that begins leaking is an environmental hazard. If the tank leaks into the soil, it will contaminate the soil. It can cost up to several thousands of dollars to remedy the leak.

  1. Your Tank is 30 Years Old or Older: If your home was built in the 1990’s or older, your oil tank is likely 30+ years old. After about 30 years or so, the interior walls of the oil tank will begin to corrode. Once the corrosion process begins, sections of the tank will begin to break and once the walls become too thin and weak, they will begin to leak. You can have the soil around the tank inspected, it is not easy. If your tank is this old, you should consider replacing it, removing it or relinquish the tank. You can begin the replacement process by deciding what tank you would like to get. We discuss Roth vs Granby style tanks in this article here.

However, you can keep a close eye on the amount of oil that you are using to determine if you have a leak or not. By keeping track of what your daily usage and gallons are, you can determine how much you’re burning and how much is leaking. You can use a Tank Chart to determine how many gallons are in your tank based on how many gallons it takes and the recorded level. Refer to this article to determine how many gallons you should have without a leak. If water starts to infiltrate your boiler, then it’s very possible that your tank is taking in water which means that oil is escaping the tank as well which can lead to an environmental disaster.
  3. You Have Plans to Sell Your Home: Sometimes an underground tanks can be a real deal breaker for potential customers. Few banks will even mortgage a home if it has a buried oil tank due to the potential for being a liability. Removing the tank and remedying the soil are often expensive and take up a lot of time. However, removing the tank will be overall a good idea to prevent potential property damage in the future that could end up being a lot more stressful than it’s worth.

After being buried underneath your yard for several decades, it’s hard to know what your tank’s condition is like.
