Abstract
An above-ground storage system, especially for use with hazardous materials is disclosed. The system includes a first inner tank and a second outer tank. An air-operated diaphragm pump is used to fill the tank. In order to prevent overfilling of the tank and, therefore environmental contamination, a valve is installed in the air supply line to the air pump. The valve is operated by a float within the tank. When the float becomes submerged in liquid the valve is closed by an arm connected to the float.
