The correct leak rate percentage that requires repairs according to EPA regulations for low pressure appliances containing over 50 pounds of refrigerant is indeed 15%. This standard is in place to ensure that refrigerants, which can be harmful to the environment and contribute to ozone depletion, are managed responsibly. When leaks exceed this percentage, it indicates significant refrigerant loss, necessitating action to repair the equipment and prevent further emissions.

Understanding this regulation helps technicians recognize the importance of regular maintenance and prompt repairs on low pressure systems, which can reduce environmental impact and improve appliance efficiency. Maintaining a leak rate below 15% is essential not only for compliance but also for cost-efficiency in refrigerant use and energy savings.
