Water Level 1 Electrical Junction Box Am_ Electrical Conduit Product Piping PEURP1200-12 there are items that must be repaired or replaced (e.g., deteriorated penetration fitting boots), notify the owner/operator and obtain approval prior to proceeding with repairs. Test boots or secondary containment termina- tion fittings must be present on the piping pen- etrating the sump. During testing, these fittings prevent water from entering the interstitial space of double-walled piping. Without these fittings, the integrity of the sump cannot be tested using this method. If interstitial monitoring sensors are present within the containment sumps, temporarily remove them before conducting the test. If the sensor is removed, reposition after testing to appropriate position according to the manufac- turer's instructions. If the containment sump is found to have cracks, loose parts or separation of any joints or penetra- tion fittings, it is not considered to be liquid- tight. This visually indicates a test failure. CAUTION: Water can damage electrical connections. Ensure that there are no components that can be damaged by the addition of water to the sump. If such components are present, take appropriate precautions when performing the test or use an alternative test method. FIGURE 6-5. The test fluid level in the UDC must be at least 4 inches above the highest sump penetration or sidewall seam. 6.5.6 Test Procedure. Begin the test by adding water to the sump to a minimum of 4 inches above the highest sump penetration or sump sidewall seam, whichever is higher. To compensate for sump deflection, the water must be allowed to settle a minimum of 15 minutes before taking the initial test measure- ment. If the highest sump penetration or sump sidewall seam is less than 4 inches from the top of the sump, add water to within 1 inch of the top of the sump. Place the measuring stick vertically at the lowest point in the sump and extending above the water level in the sump to allow for an accurate mea- surement to be taken. The location of the mea- suring stick must remain the same for each water level measurement. Document the initial water level measurement as measured from the bottom of the sump. Alternative measurement methods may be used provided that the measurement to 1/16 (0.063) inch can be made. Take all precautions to prevent the water level from being disturbed during the duration of the test. After 1 hour, document the ending water level measurement. Upon completion of the test: remove all water and properly dispose of it according to Section 6.7; reinstall any interstitial monitoring sensors in their proper positions; return the test boots or secondary contain- ment fittings to their pre-test operating con- figurations; Electrical Conduit Product Piping FIGURE 6-6. To prevent leakage, check all penetration fittings before adding water to ensure they make a tight seal. 41111) pei.org
