Signs of a Heating Oil Tank Leak

Heating Oil Tank Removal 3

Introduction

Heating oil tank leaks can be subtle—but the damage they cause isn’t. Leaking tanks pose serious environmental and financial risks, especially if left unchecked. Whether your tank is aboveground or buried, knowing the early signs of a problem can help you act quickly and avoid costly remediation. Here's what to watch for.

🚨 7 Warning Signs Your Oil Tank Might Be Leaking

Strong Fuel Odor

  • A persistent smell of heating oil around the tank or in your basement is a major red flag.

Dead or Discolored Vegetation

  • For underground tanks, dead grass or plants above the tank may signal a slow leak contaminating the soil.

Oil Stains on the Ground or Floor

  • Look for dark, oily spots around the tank base, fuel lines, or fill pipe area.

Increased Fuel Consumption

  • If your heating system is using more fuel without a corresponding change in usage, you might be losing oil through a leak.

Rust, Corrosion, or Wet Spots on Tank

  • Surface rust, bulging seams, or sweating on the tank exterior may be early signs of structural failure.

Water in the Tank

  • Condensation or water intrusion can accelerate rust and lead to tank breaches—inspect regularly for signs of moisture.

Soil or Water Contamination Nearby

  • In some cases, groundwater or well testing may reveal contamination from leaking fuel.

🛑 Why Leaks Must Be Taken Seriously

  • Leaks can contaminate soil and groundwater.

  • Homeowners may be liable for cleanup costs.

  • NYSDEC may require environmental remediation and reporting.

  • Undisclosed leaks can delay or derail home sales.
