A water alarm alerts property owners of a water leak to help prevent severe damage. The alarm may monitor the water level of a basement floor, leakage in a washing machine or any other situation in which displaced water can wreak havoc.
A water alarm is strategically placed so that an electrical connection is made once water fills the gap between its terminals. It then emits a loud sound, which owners can adjust on many devices so it is heard throughout a home or building. Some water alarms also turn off the main water line at the first sign of trouble.
