L' 3.3.3.4. Reconnect the air -supply line. Allow the pressure to stabilize at 5 psig [3 psig for a 12 -foot tank] by adding or removing air as necessary. 3.3.3.5. Close the air -supply valve on the test manifold. Disconnect the air -supply line. 3.3.3.6. Soap the entire exterior of the tank. Watch for active air bubbles, which indicate a leak. Pay special attention to fittings and manways. Lift the tank to check the bottom. Do not roll the tank. 3.3.3.7. Monitor the pressure for one hour. AWARNING Do not stand under the tank. This could result in death, serious personal injury or property damage. 3.3.3.8. When the test is complete, carefully release the air pressure from the tank by opening the air -supply valve. 3.3.3.9. When the air flow stops, remove the test manifold. r•11BLE-ITAILL TAAK '11ITA LIQIX=Ir INTERSTITIAL SPACE t . Do not «,intersfiffal-space monitor fiffing.

Keep the tank vertical (the reservoir on top) at all times or the monitoring fluid may drain from the reservoir. 3.4.1.2. Remove all temporary service fitting plugs, redope, and reinstall all fitting plugs except one (needed for test manifold) and the fitting on the reservoir. Install permanent plugs in all unused openings. Do not open the monitor fitting (if present) or monitoring fluid could be lost. 3.4.1.3. Check the liquid level in the reservoir. It should be about 1/4 full. 3.4.1.4. Visually check the interior of the tank for liquid. There should not be any. 3.4.1.5. Install the test manifold in the open service fitting. Connect the pressure source to the test manifold. (See FIGURE 3-5.) From Air Supply Air -Supply Pressure -Relief Valve Device Reservoir Air -Supply Fitting Gauge Servic Fitting 3.4.1.6. Pressurize the primary tank to 5 psig. Allow the pressure to stabilize by adding or removing air as necessary. Note: The liquid level will rise during the air test. 3.4.1.7. Close the air -supply valve on the test manifold. Disconnect the air -supply line. 3.4.1.8. Soap all service fittings and manways. Watch for active air bubbles, which indicate a leak. Check the reservoir for bubbles in the monitoring fluid. (The level of the monitoring fluid in the reservoir will naturally rise due to the pressure in the primary tank.) 3.4.1.9. Monitor the pressure for one hour. 3.4.1.10. When the test is complete, carefully release the air pressure from the tank by opening the air -supply valve. 3.4.1.11. When the air flow stops, remove the test manifold. 3.4.1.12. Check the liquid level in the reservoir. It should be at approximately the same level as the pretest level.
