the dry bilge machine
Dry Engine Room Bilge aboard the 43' Tiara SF.
Before, the engine room keel sump had a small amount of water and bilge slime. Note the diaphragm pump pickup, Diaphragm pumps can bring the residual bilge water levels down to 1/4" to 1/2" when used in the manual mode. In the automatic mode, the diaphragm pump still depends on the traditional float switch leaving 1 to 2 inches of water in the bilge. The Arid Bilge System maintains this and two other compartments 100% dry.
