## Discrepancy

AFTER TAKEOFF, AT 16,000 FEET, ALL LAVATORIES STILL INOPERATIVE.  SUCTION FEED FOR FLUSH DID NOT WORK AS PROMISED.  THE FLIGHT DECLARED AN EMER & RETURNED TO FIELD WITHOUT FURTHER INCIDENT.  THE ACFT WAS REMOVED FROM SERVICE.  FOUND SYS CB PULLED FOR NEF SYS, NOT VAC PUMP CB.  RESET SYS CB & COLLARED VAC CB.  ACFT OK FOR SERVICE IAW NEF 38-30A.
