Most drain and pipe clogs result from a combination of several small items rather than one large item. If your sink is clogged, an air compressor is a useful tool to clear the problem. The air compressor plugs into a standard 110-volt outlet and applies pressure that can be used to remove the clog. In addition to the compressor, you'll need to gather a wand fitting with a trigger, old rags, and a small plastic container before embarking on this repair.
