Abstract
Abstract A receptacle for accumulating spilled liquids about the inlet pipe of a storage tank is slidably fitted within a stationary housing. The receptacle includes an outlet spout connected to the inlet pipe. A center pipe fits within the spout for connection to a supply line. Liquid flows from the supply line through the center pipe into the tank inlet pipe. Spillage is collected in the receptacle and, if desired, permitted to flow into the tank via valved passages in the receptacle bottom.
