How can I tell if my tank is leaking?

Home heating oil tanks can be either above ground or buried underground. Both types of tanks can rust and leak over time posing a number of environmental risks.

If you have an above ground storage tank (AST), signs that your tank may be leaking include:

  • Unexpected increase in fuel oil consumption that doesn't appear to be linked to additional use of your heating system.
  • If tank is located in the basement - staining on the basement floor or wall near the tank location. If tank is located outdoors - staining on the soil or nearby structure.
  • Presence of fuel oil or sheen in the basement sump.
  • Consistent problems with your oil burner.
  • Fuel oil odor

If you have an underground storage tank (UST), signs that your tank may be leaking include:

  • Unexpected increase in fuel oil consumption that doesn't appear to be linked to additional use of your heating system.
  • Fuel oil odor
  • Oil staining on nearby structures or oil in sump.
  • Water in tank and/or furnace malfunctions
