Small leaks are best left to LDT crews to pinpoint and have repaired, instead of the <br />contractor spending hours looking for little leaks. <br />5. Fast identification and leak location substantially reduces 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 <br />repair any portion of the system. <br />3. The NMleak® method can test piping containing liquids. However if a liquid is present <br />additional 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 <br />fittings within the tank sumps during the pretesting is more efficient and less confining than <br />during the final testing. <br />3. Primary piping should be under test pressure when LDT arrives onsite. <br />Secondary Piping and Connections: <br />1. NMleak®_ does not require special fittings to be installed by the contractor. <br />2. The contractor should use standard approved factory secondary termination fittings or <br />boots. <br />3. Secondary piping should be under test pressure when LDT arrives onsite. <br />4. All termination secondary fittings shall include test ports. Test ports shall be accessible to <br />the LDT Technician. <br />Vent Piping: <br />1. Extraction plugs should be installed and sealed properly <br />2. Vent risers should not be caped and the contractor should be capable of working on the top <br />of the vent risers. <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 2of 2 <br />
