Incident Narrative

A CHECK VALVE FAILED TO CLOSE PROPERLY WHICH ALLOWED MAINLINE PRESSURE INTO THE LOW PRESSURE PIPING OF THE STATION. A STRAINER BASKET LID WITHIN THE SUCTION PIPING FAILED DUE TO THE OVERPRESSURE AND CAUSED A LEAK. THE PIPE EXPOSED TO OVERPRESSURE WAS ISOLATED AND THE CHECK VALVE AND STRAINER BASKET WERE REPLACED. AFTER COMPLETION, A STAND-UP TEST WAS CONDUCTED TO ENSURE INTEGRITY.
