Abstract
Disclosed herein is a device for injecting pressurized alcohol solution into a pipe located in a house or other structure that carries water. The device allows the user to control and adjust the pressure of the injected alcohol solution. The pressure forces the alcohol solution against the frozen water inside the pipe. The alcohol solution then acts to dissolve the ice, thereby clearing the blockage and preventing damage to the pipe. The device is hand held, portable and configurable. The embodiment of the device with the hand-operated pump does not require electricity or other sources of power. Alternate embodiments of the device can be broken down into two or more sections for easier storage. Alternate embodiments of the device has one or more of the lengths of connecting pipe or connector or adapter bends at an angle so that the device is not configured in a straight line but has a bend or curve. These alternate embodiments allows for the device to fit into tight or restricted spaces. Alternate embodiments of the device utilize fittings, connectors, valves, gauges, vents and lengths of pipe of different sizes, lengths, diameters and materials. Different solutions or solvents oth…
