When a swimmer becomes stuck to a drain or suction outlet in a swimming pool, spa, wading pool, or hot tub, the force of the filtration system can be tremendous. This "suction entrapment" will hold the bather in its grip until either the vacuum is broken, or he or she drowns, defying the rescue efforts of onlookers. The Vac-Alert Safety Vacuum Release System is a self-monitoring, non-electrical, low-maintenance safety system that responds in milliseconds to an increase in pump suction vacuum that can be caused when someone is trapped. The system's spring loaded piston reacts quickly, opening to atmosphere and releasing the life-threatening system suction.
