Underground Heating Oil Tank Leaking
The majority of residential underground heating oil tanks have an age range of 50 to 70 years, during which time the likelihood of leaks may increase.
Click below to explore several straightforward methods for assessing whether your underground heating oil tank is experiencing leaks!
You may have a leak in your tank if you smell oil around the tank, in your basement, or close to your catch basins.
If your furnace seems to be using more fuel oil than you expect or can justify with the weather, your tank may be leaking.
During the summer, turn off your furnace, measure the level of oil in your fuel tank using a tape measure or some other measuring device. Measure it again, a few weeks later. If the level is lower, then the tank is probably leaking.
Residential heating oil is dyed red which makes it easier to identify. A leak may reach the bedding area of nearby underground pipes and find a path into groundwater or surface water.
