Chain of events detected by Neptune escalation monitor:
1. FO settling tank level 18% (LOW) β likely cause: transfer pump not started before departure
2. Low header pressure at purifier feed β pressure gauge reading 0.3 bar (normal: 1.5β2.0 bar)
3. Purifier feed pump not primed β probable cavitation from air ingestion
Recommended action: Start transfer pump, prime purifier, inspect suction strainer for blockage. Check tank level sensor calibration.
