LDT has no restrictions to the MDleak@ testing Methods . <br /> 2 . LDT has several chemical markers so site contamination by a single chemical marker is not a <br /> consideration or limitation . <br /> 3 . It is best for the contactor to find the majority of the leaks using whatever method they can . Small <br /> leaks are best left to LDT crews to pinpoint than for the contractor to spend hours looking for these <br /> small leaks . <br /> 4 . Fast identification and leak location substantially reduce repair cost . <br /> General : <br /> 1 . Extraction plugs should be installed and sealed properly <br /> 2 . A construction crew shall be onsite during the test period. This crew should be equipped to repair <br /> any portion of the system. <br /> 3 . The MDleakO method can test piping containing liquids . However, if a liquid is present additional <br /> time and cost will be incurred. <br /> Product Piping : <br /> 1 . The contractor shall have all shear valves plug or capped using steel not plastic fittings and <br /> connected to the piping . <br /> 2 . It is best to complete the turbine connections before the Pretest . Locating and repairing fittings <br /> within the tank sumps during the pretesting is more efficient and less confining than during the <br /> final ELD testing . <br /> Secondary Piping and Connection . <br /> 1 . MDleak° does not require special fittings to be installed by the contractor . <br /> 2 . The contractor should use standard California approved factory secondary termination fittings or <br /> boots . Termination fittings in California require test ports . Test ports shall be accessible to the LDT <br /> Technician . <br /> Vent Piping : <br /> 1 . Extraction plugs should be installed and sealed properly <br /> 2 . Vent risers should be caped and should include test ports on each vent riser <br /> VR Piping: <br /> 1 . Extraction plugs should be installed and sealed properly <br /> 2 . VR piping at the UDC should also be caped or plug using steel not plastic fittings . <br /> Author David Rabb 5of 7 <br /> Version 191127 <br />
