High Water Sump Alarm

High Water Sump Alarm

The Grate Products Sump Alarm serves as a high water alarm in sump pump basins. The alarm horn sounds when a potentially water level condition occurs. The alarm may be activated due to a pump mechanical problem or a pump that was accidentally unplugged.

Our Sump Alarm is float activated which eliminates the annoying false alarms experienced by many other types of sensors. The alarm horn can be easily turned off, but the alarm light remains on unit the condition is corrected. Once the condition is cleared, the red light turns off and the alarm will automatically reset.
