Self Inspection Checklist for Underground

Self Inspection Checklist for Underground Home Heating Oil Tanks

If you answer “YES” to any of the following questions, call your oil burner technician for a more detailed inspection and corrective measures. (Of course, the best thing to do is to remove your underground oil tank and switch to aboveground storage.)

  • Are you using more fuel than normal?
  • Is your tank taking on water— a rise in water level greater than 1/2″ for an 8 to 12 hour period? (Your oil burner technician can check for water or provide you with water finding paste so you can check yourself.)
  • Are there signs of oil sheens in nearby streams, wetlands, or drainage ditches?
  • Are there signs of distressed (withered) vegetation over or down slope of the tank?
  • Is the tank vent clogged or restricted because of ice, snow, or insect nests? (Screened vents can be used to prevent insect nest problems.)
  • Is the overfill whistle silent when the tank is being filled? (Ask your delivery person.)
  • Are there signs of spills around the fill pipe or the vent pipe?
