Bilge Pump for Hobie Tandem Island

In this video, I install an automatic 500 gph bilge pump powered by a 10-Ah lithium battery. The pump has a built-in sensor that checks for water every 2.5 minutes. I also installed a manual override to the pump. I also show my backflow preventer which helps to keep any water in the bilge near the pump so the pump can run more efficiently.
