Building a DIY Dry Bilge Pump for a Canal Boat
I have a perfectly working automatic bilge pump on my steel canal boat. However, due to its design, it always leaves about an inch (2.5 cm) of standing water behind. Because a damp environment inside a metal boat is a recipe for rust, this always worries me. When the main bilge pump kicks in, it removes high volumes of water very quickly, but that last little bit is incredibly annoying.
