## Discrepancy

(CAN) THE AIRCRAFT POTABLE WATER SYSTEM WAS DAMAGED DUE TO HAVING THE WATER SYSTEM FULL OF WATER. THEN PARKING THE AIRCRAFT ON THE RAMP FOR 8 HRS AT -14 DEGREES C. WITH NO ADDITIONAL HEAT TO KEEP THE WATER SYSTEM FROM FREEZING.  UPON ARRIVING, THE PILOTS REPORTED (WATER APPEARS TO LEAKING FROM THE BELLY) THE MAINTENANCE PERSONAL INVESTIGATED THE PROBLEM AND FOUND THE WATER SYSTEM DRAIN VALVE WAS DAMAGED DUE TO THE SEVERE FREEZING OF THE WATER SYSTEM. THE DRAIN VALVE WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE.  A REMINDER TO ALL PILOTS TO MONITOR THE POTABLE WATER SYSTEM AND THE OAT IN THE WINTER. (TC NR 20070725002)
