## Discrepancy

POTABLE WATER SYS PRESSURE DOES NOT MAINTAIN HEAD PRESSURE AS IT SHOULD AFTER BLEEDS HAVE BEEN SHUT DOWN.  CHECKED OVERFLOW MANUAL VALVE AND FILL VALVES AND NO LEAKS NOTED.  NO WATER LEAKS NOTED IN SYS EITHER.  SYS OPERATES FINE WITH BLEED.  NO PROBLEMS NOTED NOW, HAS HISTORY.  VALVES CHECKED FOR LEAKS OF AIR OR WATER, NONE FOUND.  UNABLE TO T/S FURTHER.  FLAGGED FOR EG ASSISTANCE.
