Air Pressure/Soap Testing After the inner primary flexible pipe and piping connections have been integrity tested the entire Interstitial space of the GeoFlex Pipe must remain connected and only then should the outer containment jacket be integrity tested. The connections of the Test Boots are Illustrated and explained on page 15 of this product manual. Testing Assembly Inside all Tank Sumps the Test Gauge Is connected to the brass fitting at the end of the 36" (900mm) long Test Tube. The Test Gauge assembly consists of an air gauge with a maximum 15 psi scale connected to a 114" brass tee fitting which will thread into the brass fitting at the end of the Test Tube. Wrap male threads with teflon tape to Insure a good seal. Connect air hoses directly to the brass tee fitting as illustrated. Air Pressure Testing Gradually apply air through the Test Gauge and Connector Tube into the Interstitial piping line. The interstitial space of the GeoFlex Piping Is very small and will not require a large volume of air. Pressurize system to no more than 10 pal. During the pressurization period apply soapy water to the entire length of the piping system and check for any air bubbles. After testing disconnect the Test Gauge and lay the Test Tube down into the bottom of the Tank Sump. i Routine Sump Inspections Visual Inspections of all containment sumps should be made on a routine basis to check for water infiltration or for any signs of leaking product. An electronic or mechanical shut-off leak detection system is recommended for all containment sumps. When changing fuel filters at the dispenser, make sure any spilled product is cleaned out of the bottom of the dispenser sump to prevent a possible fire hazard. Periodic Interstitial Testing Should periodic integrity testing be required to check the integrity of the outer containment wall of the coaxial pipe, reconnect the test boot connector tubes and initiate an air pressure hold test not to exceed ten pounds per square Inch (10 psi).
