E 15.1.3 Terminating Dispenser Sumps Test boots installed in these sumps should be connected to the 36" (914mm) long test tubes and plugged on the end when conducting the air pressure test. 15.1.4 In-line Piping Sump Connections Test boots installed in these sumps should be interconnected with a custom length connector tube. 15.2 Installing Test Boots After all pipe sections have been inserted into the containment sumps and before any piping connections are made, the rubber test boots must be installed first. The test boot has an outlet opening located on the bottom for connection to either test tubes or connector tube as described in section 16 Tubing Assemblies of this product manual. Comply with the following three step installation procedures for proper installation of the test boots. Standard Test Boots (Swivel) Position the Test Boot with the outlet port facing down. Align the boot so that one clamp is over the green secondary jacket and the other clamp is over the metal ferrule of the pipe coupling. Next tighten down band clamps to 30 in/ lbs. 15.2.1 Removing Band Clamps Remove both band clamps from the test boot before installing the rubber boot over the end of the coupled flexible pipe section. 15.2.2 Installing Test Boot From inside the containment sump, slide the test boot over the installed pipe section end of the pipe section. 16.0 TUBING ASSEMBLIES OPW-FCS flexible piping systems incorporates the use of plastic tubing for purposes of providing convenient access to, and interconnecting of the interstitial space of the double wall flexible piping line. Double wall piping having either swivel or barbed piping connections and installed with test boots can be fitted with both test tubes and connector tubes. Double wall piping having coax piping connections can be fitted using only coax test tubes. 16.1 Test Tubes There are two types of test tubes available for use with double wall piping: one for connection to coaxial fittings & adapters and the other for connection to test boots installed with swivel piping connections. These 36" (914mm) long plastic tubes assemblies are designed to provide convenient access to the beginning and end of a double wall pipe line for initial and periodic air pressure integrity testing. 16 F17EMWOO BY DPW FUELING CONTAINMENT SYSTEMS 101111111111111 . :a These 3/8" tubes are 36" long (914mm) with a 1/4" female fitting installed on one end. The other end has a nylon male 1/4" NPT threaded connection which connects to the 1/4" NPT threaded test port of the coax pipe adapter. CAUTION: Do not install metallic fittings into Coax test ports. 16.1.2 Standard Test Tubes These 3/8" tubes are 36" long (914mm) with a 1/4" female brass fitting installed on one end. The other end has a male barbed elbow with band clamp attached for connection to the 3/8" port of the rubber test boot used with metallic couplings & fittings. 16.2 Connector Tubes These short plastic tube assemblies connect one test boot to another to reroute the interstitial space of one flexible pipe section around a tee or connector fitting to the next flexible pipe section. 16.2.1 Connected Connector Tubes After initial integrity testing has been completed, the connector tubes can remain connected if interstitial product flow is desired to run the length of the pipe line back to the tank sump. NOTE: Dispenser sump leak detection is required to monitor the integrity of piping, when the connector tubes are connected. 16.2.2 Disconnected Connector Tubes After initial integrity testing has been completed, the connector tubes can be disconnected if interstitial product flow is desired from sump to sump. One end in each dispenser sump should be disconnected from the test boot. 17.0 INSTALLING CROSSOVER SUPPORTS Crossover supports should be used at all locations where flexible pipe crosses over another flexible pipe and at any rigid piping or conduit crossovers. These two-piece supports are installed to both the upper and lower flexible pipe sections. They must be installed before backfill begins. They are designed to provide a flat crossover surface for the upper pipe and also allow for even backfill compaction around both flexible pipes. To install, align upper and lower support as shown in illustration and fasten together using the supplied clips. Be certain not to scratch piping while installing clips. Note: When crossover supports are not available, a minimum compacted layer of either 2" of approved pea gravel or crushed stone or 4" of approved sand backfill must separate each pipe. 18.0 VENT FLEXIBLE VENT PIPING This flexible piping is used for the transmission of aromatic fuel vapors and is designed for direct burial of the pipe and fittings without the requirement for secondary containment. The intended use for Vent is for venting vapors from an underground storage tank to a remotely located vent stack.
