Abstract
A device for preventing the overflow of a fluid reservoir, having a first tubular body with a hole through the interior and exterior surfaces at one end, a second tubular body disposed within the first body such that a portion of the interior surface of the first body and the exterior surface of the second body define an air channel, and a floatation device. The position of the tubular bodies relative to one another determine whether air from a fluid reservoir may exit the reservoir via the hole in the end of the first body. The flotation device is connected to an end of the second body and floats in the fluid reservoir wherein movement of the second body relative to the first body is caused by a change in the water level, such that the air channel is opened or closed by the position of the floatation device.
