    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. Configured to automatically cycle for 2 minutes every 6 hours if you decline Smart Device connectivity.  Newly designed, ruggedized, single pump, which includes: An anodized aluminum enclosure with improved durability, enhanced pump efficiency, and streamlined internal plumbing. Four hard points for mounting in extreme conditions. Reduced size for easy installation in tight compartments. BILGE-B-DRY connects to your Smart Device (if desired) through the free Mobile App on the APPLE & GOOGLE PLAY stores. Customizable operation is at your fingertips with two options:  Run the “TIMER” option up to 20 minutes after boating in heavy seas or upon washdown.  Choose the “SCHEDULE” option for five customizable run times during the day, up to 20 minutes. 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. If at 8:00 PM you still see water in your bilge, run the on-demand Timer for up to 20 minutes to remove the remaining water. BBD Single Pump 12VDC: One motor/diaphragm pump 10 feet of input tubing provided (for pickup) 6 feet of output tubing provided (for discharge) Input tubing diameter (PVC or PU) - 1/4” OD  Output tubing diameter (PVC or PU)-3/8” OD Included with your BILGE-B-DRY purchase are low-profile bilge water pickups. Our uniquely designed low-profile bilge water pickup (bracket sold separately) with a replaceable filter helps reduce the harmful overboard discharge of heavy metals, solids, and petroleum. 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.
