ABSTRACT:
A pumpless bilge water draining system combines a valve system and vented air loop apparatus. The vented air loop is bracketed above the load water line for positive control of the system as well as preventing the system from falling below the water line and endangering the vessel. In motion, a vessel travelling at a sufficient speed will produce a vacuum in the system thus draining accumulated water in the bilge area through the system's pick-up; and at rest, a ball valve is utilized, in an engaged position, to close the valve when it is desired to do so.
