Water Witch 257B Dual Bilge Pump Switch with Buzzer Notification. lets boat owners install two systems in one product. The primary protection activates a bilge pump when it senses the presence of water and the secondary, for added protection or a backup against primary system failure, activates a second bilge pump.

The 257B’s monitoring system is constantly on guard and will activate the primary bilge pump when it detects water for 8 continuous seconds. The 257B’s secondary system will activate only when the pump runs for 2 continuous minutes. The monitoring and secondary systems work hand-in-hand to provide previously unavailable protection in one electronic control. The 257B can be connected to any auxiliary system such as a second bilge pump, audio alarm or visual alarm.

The 257B meets or exceeds the Canadian & U.S. Coast Guard standards and comes with an unmatched 7 year limited warranty.

Sometimes sticks on


Works but sometimes sticks on and then the alarm goes off. The only way to get it to shut off is to pull the fuse for a few seconds.
