Frequently seen questions: -The water leakage alarm will give an alarm when there is no water leakage. It may be caused by the water leakage alarm being placed on the metal conductor, which will cause the trigger. Please put a piece of paper under the water leakage alarm -In case of water leakage, the water leakage alarm does not sound an alarm. One reason is that the placement method of the water leak alarm is incorrect. The correct method is to lay the water leak alarm flat on the place where the water leak may occur, with the buzzer hole facing upward. The detection head is facing down, so that the sensor of the alarm (that is, the two touching the metal) can easily contact the water. Another reason is that the battery voltage is too low, which prevents it from working and should be replaced with a new battery.
