In the bilge pump arena, one of the highest failure-rate items is the float switch, which can now be replaced by a Bilge Pro sensor that uses the same technology as many touch-screen tablets. The sensor is available through a British company, Energy Solutions Ltd., and should be in the United States by the time you read this. The sensor has no moving parts, is hermetically sealed and employs waterproof push-and-lock plug connectors to wire it into an existing bilge-pump system. The device is so sensitive that it can detect whether there is oil in the bilge water, and if so, it will not pump. That little nuance could save you a potential $5,000 fine in some cruising areas. The sensor is also multistaged. As long as you have a bilge high-water alarm system (and you should if you have sleeping accommodations on board), it will sound if the water level gets high enough without the pump turning on. Another novel idea is the sensor’s automatic pump-exercise feature. It’s common for bilge-pump motors to seize when they sit idle for long periods. The Bilge Pro system periodically switches the bilge pump on for a few seconds to keep things from jamming up. With no moving parts and being sealed against water ingress, this sensor takes bilge-pump switching to the next level.
