What can be a sign of a vapor recovery system needing maintenance?

Variability in vapor capture rates is a clear sign that a vapor recovery system may need maintenance. Vapor recovery systems are designed to efficiently collect and recover vapors released during the transfer of fuels, and any inconsistencies in capture rates indicate that something within the system may be malfunctioning or less effective than intended. This variability could stem from several issues, including blockages, compressor failures, or faulty valves, which could lead to increased emissions and potential regulatory compliance issues.

While consistent performance over time and regular upkeep without issues suggest that a system is functioning well, they do not directly indicate a need for maintenance. Similarly, having documentation that is up to date is important for compliance and record-keeping but does not provide insight into the operational condition of the vapor recovery system itself. Therefore, noticing fluctuations in vapor capture rates necessitates immediate attention to identify and resolve any underlying issues, ensuring that the system continues operating effectively and in compliance with environmental regulations.
