This was designed for a friend had a leak in his house and found that the Insteon Leak Sensor was not water resent and the device shorted. The design is to raise the sensor up off the floor and in the case of extreme flooding float the sensor.

You will need 2 - 5MM stainless steel balls and 2 pin springs to move the electrical contact to the ground. For best contact of the detectors sensor extenders there are 2 holes for zip ties to be placed.
