Quick Answer
Signs of a buried propane tank needing replacement include rust spots, dents, and cracks in the tank, as well as corrosion on the tank's connections, valves, and fittings. Leaks, rust accumulation, and damage to the tank's coating can also indicate the need for replacement. Visible signs of wear and tear on the tank's exterior often signal internal damage.
Signs of Rust and Corrosion
When inspecting a buried propane tank, look for rust spots, especially around the tank’s connections, valves, and fittings. Check the tank’s coating for any signs of wear, cracks, or complete breakdown. Corrosion on these areas can lead to leaks and internal damage, compromising the tank’s integrity. If you find rust accumulation, inspect the tank’s interior for any signs of internal corrosion.
Leaks and Pressure Tests
Perform a pressure test on the tank to identify any leaks. A pressure test can help you determine if the tank is still safe to use. If you find any leaks, consider replacing the tank to prevent gas escaping and creating safety hazards. Leaks can be difficult to detect, so be thorough in your inspection and testing.
Inspection and Maintenance Best Practices
For a thorough inspection, use a non-invasive tank inspection method, such as a magnetic particle inspection or radiographic testing. These methods can help you detect internal damage and corrosion without damaging the tank. Regular maintenance, including cleaning the tank’s connections and valves, can also help extend the tank’s lifespan.
