Water Alarm, Battery-operated

Basement Watchdog Water Alarm detects unwanted water only 1/32″ deep. It is placed on the floor near water heaters, sump pump pits, washing machines, and under sinks. The sensor has a 6′ wire so it can be extended into a sump pump or mounted on a wall and stretched to another location. It has a loud 110Db alarm and a battery saver feature that keeps batteries fresh longer. It uses one 9V battery (not included). It comes with a 5-year warranty.
