In the structure of plumbing, the drain is what takes away what is no longer wanted or needed. Often what is being drained would fall into the category of waste or things of an unsanitary nature. Therefore, as a symbol, the drain represents your ability to slough off the old and easily release the past.

If the drain in your dream is functioning properly, all is well.

If it is not, there may be some need to examine why you are unable to let things go.
