What capability must automatic line leak detectors installed on underground piping have?

2 gallons per hour at 10 psi
5 gallons per hour at 10 psi
3 gallons per hour at 10 psi
1 gallon per hour at 10 psi

The correct answer is: 3 gallons per hour at 10 psi

Automatic line leak detectors installed on underground piping must have the capability to detect a minimum leak rate to ensure environmental safety and regulatory compliance. The correct answer indicates that these detectors are designed to identify leaks that may occur and that the threshold for detection is set at 3 gallons per hour at a pressure of 10 psi. This standard is established to effectively minimize the risk of contamination due to leaks from underground storage tanks, ensuring that any potential leak is identified quickly and accurately. A lower detection threshold enhances the ability to monitor the integrity of the piping and take corrective action before significant product loss occurs, which is critical for protecting the environment and maintaining compliance with regulatory requirements.
