Rated 2 out of 5 by Not Sure Doesn't seem to function quite right. I bought it as a replacement float for my bilge pump in a Pelican Bass Raider 10E that I leave tied to my dock all summer. As of now, it has actually never actuated due to water being around it. In the directions, it states to hold a wet towel between the senors as a test. This works just fine, but water itself doesn't seem to be enough to complete the circuit. If you keep reattaching it to the battery it will run a 60 second test mode, and that's how I've been pumping it as of now. I'm going to try to fully charge the battery to see how that affects it, but I'd really hate to have to have a 100% charge for it to work right. Maybe its just mine or maybe a design flaw?

Answer this Question


The water is supposed to activate the switch once the whole thing is completely covered. The metal disk on top is the second sensor needed to complete the circuit. Its not adjustable. I would say its something like 2-3 inches tall. The switch is designed to run for 60 seconds after water has stopped touching the top contact. So you would have however much left in your bilge below the level of the float that your pump can't pump in that 60 seconds.
