Figure 1 F Reservoir and Sensor Located in Tank Sump REPEATING: This configuration can only be used if the low level alarm point on the sensor is above the highest point of the containment pipe through the rest of the system. To connect the 3-inch diameter pipe of the reservoir, the applicable leg of the containment tee is cut at the beginning of the tapered surface. This same technique is used for the termination ring for the containment around the primary fitting. See Figure 2. 1-i-- r-� O O I 0 0 0 Figure 2 NOTE: The "LCX" clamshell fittings were specifically designed to allow connection of the next-size-larger single wall pipe to the center portion of the fitting. This feature not only allows this connection for the brine filled containment system, it also allows low-profile crossover assemblies to be made. For assembly in the tank sump (Figure 1 F), a primary coupling is installed in the line, then contained by a clamshell tee. Only the branch of the tee is cut at the tapered portion to accommodate the reservoir made of 3-inch pipe. III. Piping Testing Once all the piping is in place, each portion is air tested. The primary system air test in conducted exactly as is done for any non-brine filled system. The containment system is air tested prior to the introduction of the brine. After the containment system piping is completed, a threaded end cap should be placed on the Bell x Male NPT adapter on the end of the reservoir. The end cap can be drilled and tapped for inclusion of a pressure gauge if desired. Threads of the adapter should be coated with pipe dope and/or tape to fully seal against the fiberglass adapter.
