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!)?

Open up this connection and make sure the gasket inside is not damaged. I put one in once and the gasket was not in right, it got crushed causing a leak.

Ou know what you are looking at, but sometimes it is hard to describe it in words. Is the leak between 2 different parts of the same piece or between 2 different pieces? If it is one piece, it could have been defective and the store should exchange it for a good one. If it is 2 different pieces, there should be a flange, gasket, and nut on a thread. Remove the nut and examine the gasket. They are easy to damage. If it looks good, try tightening the joint up tighter. It that doesn't fix the problem, a new gasket is cheap, try it again.

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

Hey scott,
I know exactly what you are talking about. I just installed a new sink and drain in my bathroom and I am having the same problem. I don' t understand why it would be leaking from where it is? It should be all one piece. There is no seal in that portion of the drain assembly so there is no way to tighten it or use putty to fix it. I too have checked all the other connections above where it is leaking along with where the stopper arm connects and nothing else is leaking. If you figure out how to fix it please let me know, I really don't want to take it all back out and put another one in. If I figure it out I will let you know.

I had the same leak happen to me today. Has anyone figured it out??

Hey cypressTX:

You are in a post that goes all the way back to 2005.

Repost your question as a new thread.. include all information you can provide us and we will see if we can help.

Thanks... Mark

Hi Scottio is it possible if you take a picture of it and post indicate where the leak is will help

You want the guy from Feb 2005 to come post a new picture?? I'm betting he has fixed his leak by now or drown.

I had this happen yesterday. I know this is an old post, but I found it...

It was hard to understand how the water could make it through the nut and threaded plastic drain pipe.

I fixed it by loosening the nut that holds the rubber wedge washer up to the bottom of the sink and putting teflon paste on the threads that will be covered by the rubber washer. When I retightened the nut the leak was gone.

Bob I am sorry I meant sypresst.

In case anyone else has this problem, I discovered that what comes as one piece in the package is really two. I have a different brand, but the issue is the same from what I could tell. This video made in clear to me. No where in the directions did they tell me to separate those pieces and reconnect with the teflon tape. It looks like it's all one welded piece. I'm posting the benefit of others who may run into this. See video below.

I found that what looks like one piece when you buy the assobly is really two. See the video and you will know what I mean even though my brand is different.
