What is the recommended range for the pressure gauge used to conduct a tank air test?

The recommended range for the pressure gauge used to conduct a tank air test is typically between 10-15 Psi. This range is optimal for accurately assessing the integrity of underground storage tanks. It strikes a balance between being high enough to identify potential leaks or weaknesses in the tank structure and low enough to prevent any risk of over-pressurizing the tank, which could lead to damage or inaccurate results.

Conducting the air test within this range allows for effective monitoring of the tank's pressure changes, which can indicate whether there are any leaks present. If the pressure falls outside of this recommended range, it may not provide reliable data for assessing the tank's condition. Thus, utilizing a gauge that falls within the 10-15 Psi range ensures compliance with safety protocols and regulatory standards for UST testing.
