Abstract
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.
