    Single Pump - 12VDCBILGE-B-DRY is the world’s only Smart Device-enabled Dry Bilge System on the market!Enjoy simple installation and customized scheduling control at your fingertips with our Mobile App for Apple or Android devices. Due to size and placement, traditional bilge pumps cannot remove the last few inches of excess water accumulating in your bilge. With BILGE-B-DRY, you can finally eliminate cabin odors, reduce mold or corrosion, and protect your electrical wiring by removing every drop of water from your bilge. Your cabin will be odor-free, and your bilge will be the driest and cleanest at the marina!Why choose BILGE-B-DRY? Take advantage of: The world’s ONLY Smart Device-enabled Dry Bilge System on the market with customizable operation!  An efficient, reliable method to remove excess bilge water on all boats, including stepped-hull boats where water sits forward of the “step. Use BILGE-B-DRY after washdown, heavy rain or sea spray accumulation, rough seas, untreated leaks, etc.  A choice of four pump configurations in 12vdc or 24vdc for optimal water removal.  Pump diaphragm design can run dry for extended periods of time without damage.  A compact pump design for easy installation in tight or awkward spaces in any orientation (horizontal or vertical). Customized pump scheduling with the free Mobile App for Apple and Android devices.  Quick disconnect wiring harness with optional connection to a helm or float switch. An environmentally friendly, low-profile bilge water pickup design with a replaceable filter system.

This is a great option if you will be away from your boat for a few weeks.  Example:  With your Smart Device, schedule your BILGE-B-DRY to run at 9:00 AM for three minutes and again at 3:00 PM for two minutes. The schedules will run daily until canceled.

Place the pickups wherever you wish to remove water, such as the lowest part of your bilge, A/C evaporator, or hard-to-reach compartments. Twenty small holes along the bottom of the pickup provide a debris barrier. The pickup’s integrated filter contains a proprietary blend of materials to prevent damage to the BILGE-B-DRY pump and to reduce oil discharge, which, unlike other dry bilge systems, eliminates the need for a secondary filter.For optimum performance of your BILGE-B-DRY unit, replace the low-profile bilge water pickups when the flow rate has decreased.
