Abstract
A low power consumption leak detection device for a toilet tank includes a water level switch disposed within the toilet tank having a float. The float moves with a water level within the toilet tank from a starting position to a lower position. An electronic circuit is configured to be electrically disconnected from a power source when the float is in the starting position. The electronic circuit is configured to be electrically connected to the power source when the float is in the lower position and activate a timer having a preset time limit, which if reached sends an alarm signal to an alarm indicator. The alarm indicator notifies a resident of a potential water leak problem that can be fixed. The lower power consumption leak detection device only uses power when the water level drops thereby greatly extending the life of the battery and usefulness of the device.
