What does a high-pressure indication in a vapor recovery system usually indicate?

A high-pressure indication in a vapor recovery system typically suggests there may be potential blockages or failures in the recovery line. This condition often results from obstructions in the vapor line that prevent vapor from flowing freely. As vapor builds up due to these blockages, the pressure rises, indicating that the system is not operating efficiently or as intended.

Monitoring pressure levels is crucial in vapor recovery systems because they are designed to function within specific pressure ranges. Deviations from these ranges, particularly an increase in pressure, can lead to safety hazards, reduced recovery efficiency, and potential system damage. Therefore, identifying high-pressure readings allows technicians to investigate and address any issues before they lead to more significant problems or system failure.

In contrast, indications of optimal functioning or normal operation would typically be associated with stable and expected pressure levels within the system. A system being ready for operation does not directly correlate with high pressure, as that typically signifies an issue requiring immediate attention.
