Abstract: The present invention relates to a system for using compressed air to dislodge a clog from a drain. The system includes a main housing defined by a handle component and a minor housing component. The handle component includes a rod and piston for use in delivering compressed air to the minor housing. The device further includes a spring-biased trigger for use in selectively delivering compressed air from the device into a clogged drain. Furthermore, the system of the present invention includes a plurality of drain closure members of various sizes adapted to fit into various sized drains. Thus, the user may select the appropriate sized drain closure depending on the specific application of the device.
