I think most sinks have three pipes into the wall under the bathroom sink. The hot water, cold water and drain pipe. I have a fourth pipe that connects above the trap. What is this pipe? You can see a picture of the pipes under my sink here:

I have turned the water shutoffs off and disconnected the trap and there is water leaking from this fourth pipe which would normally go down the drain. I found this problem because I think the drain got clogged and the water backed up into my sink. So first, I'm not sure what this pipe is for. And second, I'm not sure why water would be coming in through it.
Thanks very much!
