: The tank must sit on a solid, level concrete pad. Uneven legs can lead to stress fractures or a catastrophic collapse.
: Look for "weeping" seams, heavy rust, dents, or oil staining around the base and legs.
: Outdoor tanks are exposed to snow, ice, and falling branches, which can damage lines or cause "gelled" oil in extreme cold (below 16°F). Buying a House with an Abandoned Oil Tank - GreenTRAX, Inc. buying a house with an above ground oil tank

Buying a home with an aboveground oil tank (AST) is generally lower-risk than one with a buried tank, but it still requires careful due diligence to avoid environmental liabilities and unexpected replacement costs. Essential Inspections : The tank must sit on a solid, level concrete pad
: Even if the current tank looks clean, testing the soil underneath is critical to ensure no previous tanks leaked in that same spot.
: Professional inspectors may use ultrasonic testing to measure the thickness of the tank walls, as they often corrode from the inside out due to water buildup. Key Risks & Considerations : Outdoor tanks are exposed to snow, ice,
: While leaks are visible, an uncontained spill can still reach groundwater or neighboring properties, costing between $20,000 to $90,000+ for remediation.
