Abstract

A fluidizing apparatus, such as a winterizing apparatus, and related method for preventing freezing of water in the water pipes of a dwelling. The apparatus includes a pump, an inlet line, an outlet line, a pressure switch, and an air compressor tank. The outlet line is connected to a faucet of the water pipes of the dwelling and the inlet line is positioned in a container of fluid, such as antifreeze. When a second faucet is opened, the pump is activated, and the pump will then cause antifreeze to flow from the container, through the inlet line, the pump, and the outlet line, and then into the faucet and through the water pipes of the dwelling. An associated air compressor tank is in fluid communication with the pressure switch and exit line, and cooperates with the pressure switch to maintain consistent pumping of the antifreeze. After antifreeze is in the pipes, a shut-off valve in the exit line is closed and/or the at least one valved water outlet is closed, which causes the pump to deactivate.
