ABSTRACT:
A safety device for use in a fluid transfer system for a swimming pool or similiar application, having a pump which draws water from a reservoir through one or more intake lines each extending from an open end at the reservoir to the pump intake. The device analyzes negative pressure levels in the system and, upon detecting a negative pressure level being outside of a selected operational range, the device deactivates the pump and triggers a vacuum breaker device to eliminate negative pressure in the system, by introducing air from atmosphere into the intake lines thereby removing suction at the open ends of the intake lines. The safety device may further activate warning devices including audible and visible alarms to indicate that the system has been deactivated.
