Abstract
A wand having a length of flexible hose extending therefrom is inserted within an underground fluid filled storage tank. Through actuation of a propulsion system, the wand is directed to a suspected vapor pocket within the tank and temporarily retained in place by floatation. An evacuating pump draws in the vapor through inlets at the extremity of the wand and through the trailing hose to reduce or eliminate the vapor pocket within the tank. Upon elimination of the vapor pocket to a practical extent, the hose and attached wand are withdrawn from the tank.
