An APak® Alarm System from Zoeller Pump Company monitors liquid in pump chambers, basins, holding tanks, and other water systems. The device can notify you if the water level presents the danger of overflow, giving you time to act and protect your property from flooding. During standard operation, a green light indicates that the power is on. A red light appears when the system senses high water.

You can set the system to emit a loud horn sound in the event of high water levels. Once the situation is remedied, the red light automatically turns off and the system resets. A chirping noise indicates a low battery — the system uses two AA batteries for easy replacement.

These indoor alarms have a compact design and some feature built-in Wi-Fi for remote connectivity and control, ensuring you stay informed about the water level in your sump pit. With an APak® alarm in place, you can monitor your pump from anywhere.
