Sound Familiar?
Gauge Stuck or Inaccurate
Your tank gauge reads the same level for weeks, or shows full when you know you're low on fuel.
Visible Rust or Wet Spots
Orange rust spots on the tank exterior, or wet/oily areas beneath or around the tank.
Frequent Filter Clogs
Oil filter needs replacing more often than usual—sign of sludge or water contamination in tank.
Whistling from Vent
Unusual whistling or gurgling sounds from the tank vent pipe during deliveries or temperature changes.
Understanding Oil Tank Problems
Your oil tank is critical infrastructure—when it fails, you lose heat and potentially face expensive environmental cleanup. Most Nassau County homes have tanks that are 15-30+ years old, well past their typical lifespan.
Common issues include rust (both internal and external), gauge failures, water contamination from condensation, and sludge buildup from old fuel. Catching these problems early can save thousands in emergency replacements and spill remediation.
