A system for administering acid to a clogged drain, and the method of using the system. The system includes a coupling to which a container of the acid can be threadedly secured. The coupling includes a piercing nipple, which penetrates a seal on the acid bottle. The nipple is hollow, and the acid passes from the bottle through the nipple and into a rigid, but arcuately deformable, tube that is connected to the coupling and is in fluid communication with the nipple. The tube is inserted into the clogged drain, until it is embedded in the clog. The acid is delivered directly to the clog, where it reacts with and dissolves the same.

A system for removing a clog from a drain comprising a container of a liquid which will react with and dissolve said clog, a coupling arranged for location at a predetermined position with respect to said drain, said coupling receiving a portion of said container, said coupling having securing means thereon securing said portion of said container to said coupling, said coupling having an open top and a closed bottom, an opening formed in the bottom, hollow piercing means secured in and projecting upwardly from the opening, and an elongated hollow tube connected to and depending from said coupling within said drain when said coupling is at said predetermined position, said tube being non-collapsible longitudinally, but being arcuately bendable, and terminating in a free end configured to penetrate said clog, said tube being in fluid communication with said piercing means and having at least one aperture therein, whereby the location of said coupling at said predetermined position causes said tube to penetrate said clog and be in fluid communication with said clog through said aperture, and whereby the securement of said portion of said liquid container to said coupling results in the piercing means piercing said portion of said container, thereby permitting the flow of liquid from said container, through said piercing means, said tube, and said aperture into engagement with said clog.
