If an inner-wall leak occurs, the brine solution 5 seeps into the tank. If an outer-wall leak occurs, the =� brine solution leaks out of the tank. In both cases, ;4 the brine level decreases and the Single Float Sensor triggers a low level alarm. / The housing is constructed of clear PVC, allowing *;< the operator to pull the sensor from the reservoir to visually inspect float operation.
