Abstract: A leak alarm includes a liquid flow detector and an electronic alarm circuit having a first timer, a second timer cooperable with and electrically connected to the first timer, and an alarm electrically connected to the second timer. The first timer has a first timer cycle time and the second timer has a second timer cycle time. The first timer cycle time is shorter in time than the second timer cycle time. The liquid flow detector is electrically connected to the electronic alarm circuit. The first timer resets itself to zero when the liquid flow detector senses a flow of liquid, the first timer resets both itself and the second timer to zero when the first timer reaches the first timer cycle time, and the second timer triggers the alarm when the second timer reaches the second timer cycle time.
