## Discrepancy

CREW REPORTED A BLEED 1 LEAK MESSAGE ON CLIMBOUT WITH A BLEED 1 CLOSED MESSAGE AT THE SAME TIME.  THE MESSAGE REMAINED ON UNTIL CROSS BLEED WAS CLOSED AND BLEED 1 PUSH BUTTON WAS DESELECTED AND THE AIRCRAFT DIVERTED TO KCMH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE TROUBLESHOT THE FAULT AND FOUND THE O-RINGS TORN AT JOINTS 17, 23, 25, AND 28.  THE O-RINGS WERE REPLACED WITH NO FURTHER LEAKS NOTED.
