A fluid flushing and pressurization apparatus for use with geothermal systems, capable of delivering a reversible high-velocity flow of fluid through a system of buried PE pipe without introducing an overpressure condition or water hammer. The moisture sensing device includes a moisture sensor that is operably positionable relative to a moisture collecting surface. For example, the SCBF may access a subscriber location memory to determine a location of the UE and an eNB associated with the location. The first connection setting information specifies a first output port to which a signal input via an input port is to be output, in association with identification information identifying the signal, and the second connection setting information specifies a second output port to which the signal is to be alternatively output.
