The wireless water sensor will detect less than a 1/4 inch of water in your bilge.  When the sensor detects water, the BILGE-B-DRY pump will run and continue to run until the sensor no longer detects any water. BILGE-B-DRY will run for one additional minute after the water sensor stops detecting water to ensure a completely dry bilge.  The wireless sensor will automatically connect to your BILGE-B-DRY pump -  no pairing or setup required.
 
The battery is a replaceable CR2032 cell with a one year life expectancy.
Multiple wired and wireless sensors can be used in different compartments.
It is recommended to place your sensor(s) near your bilge water pickup.
