## Discrepancy

IAH - FLIGHT 2582 - THE CREW REPORTED THAT THE PRESSURIZTION FAILED IN AUTO AND MANUAL AFTER TAKEOFF.  THE AIRCRAFT RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE GROUND AIR CONDITIONING FLAPPER VALVE, OPERATIONALLY CHECKED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
