Leak in new bathroom sink drain
I spent the morning removing my old sink drain and replacing it with a new one. After attaching everything I noted a persistent leak in the pipe at the middle of the new drain. I checked all of the connections, and it does not seem to be coming from these areas. It appears that the leak is coming from the portion of the new pipe that connects the section that has the hole on the back for the mechanism that opens and closes the drain and the portion of the pipe that connects to the trap. In other words, there is the part that attaches the pipe to the sink, then (below the threads) is the section that has the open/close mechanism coming out the back (the only way I can explain this section of the pipe is that it is not smooth), and finally there is the smooth part of the pipe that ultimately is attached to the trap. The leak seems to be coming from the seam between the unsmooth part and the smooth part. It seems strange, though, as this is a brand new fitting and there is nothing for me to attach there (i.e. it isn't because I didn't tighten something enough, as this is merely all one piece). Anyone have any suggestions or should I just go buy another drain (despite this one being brand new!)?

Hey Scott,
Let's you and I get together on terms.
Bathroom sink = Lavatory, sinks are in the kitchen
Lavatory Drain = Pop-up waste
The pipe that connects to the pop-up and connects to the trap is called a tailpiece.
Now let's address your leak. Labman and Tommy read your leak as coming out of the nut that has the rod coming out of it that pops the stopper up and down.
I have a different take on your complaint.
"The leak seems to be coming from the seam between the unsmooth part and the smooth part."
If by "seam" you mean the threads between the drain and the pop-up, then go back and teflon tape the threads and try again. Anything else, take a wad of toilet paper and start at the top near the drain and let me know where you first run into moisture.
If the leak is indeed coming from the nut the rod goes through or the welded seam that that attaches the threads and threaded cap, (the rough part) then the popup's faulty and should be returned for replacement. Good luck, Tom
