At what pressure is a tank typically tested?

The typical pressure for testing a tank is 5 PSI. This pressure is considered sufficient to ensure the integrity and safety of the tank without being unduly strenuous on its structure. Testing at this level allows for the detection of any potential leaks or weaknesses in the tank material or joint seals, ensuring that it will function safely under normal operating conditions.

Testing at 5 PSI is also a standard practice that aligns with industry regulations, providing a balance between being thorough enough to identify issues while avoiding excessively high stress that could lead to false results or damage the tank. This practice helps maintain safety standards in fuel handling and storage, which is a crucial aspect of the regulations governed by the Maine Journeyman Oil Fuel Board.
