Need to Make a Drain


There should be no leaks, at all. If I had to guess it's leaking because it looks like you've got that tail piece bent over to reach that flex line. And in the process have caused the threads to fail to keep a good seal. Either that or there's no plumber's putty under the drain where it comes down through the sink.

It might be worthwhile disassembling the whole drain from the sink and reassembling it properly. That way you'd at least know the right steps were followed.

On a separate note, any reason why there is a slight trickle on the threads immediately under the sink (where the large nut and rubber washer are)? It's really slight right now, but I worry it'll only get worse over time.

IMO you want to use a 1.5" female apt onto the nipple where the stuck nut was. Then use either a street 45 or 22 to get the angle lined up to the tailpiece. Then glue on 1.5 x 1.25" trap adapter to receive the trap. All material I listed are common over the counter 1.5" DWV fittings(abs or pvc)
As for the leak, this happens sometimes. Backoff the tailpeice nut and apply pipe dope to the threads and retighten nut. Normally pipe dope doesn't belong there but it has become a habit of mine to do it. Usually stops the drip

That's a leak.



Seriously though, the easiest way i've found is to use toilet paper to dry the entire drain assembly thoroughly, fill the sink completely to the top, and let it go all at once. This will create a little pressure on the drain and the leaks will show better. If you can't see it, use the toilet paper again to find the highest point that is wet. That will tell you which joint is leaking.


If it is the popup assembly at the sink, sometimes you have to pull the darn thing off, back the nut and washer off a little bit, and put a bead of caulking around the threads just above the rubber washer. Picture this : When you tighten the nut against the rubber washer, the washer will slide up the assembly pushing the caulking into the threads and sealing them.

Sometimes the washer just isn't flexible enough to squish into the threads and seal them.

Did you use plumber's putty on the sink side of the assembly?

Need to Make a Drain


On the sink (top) side I used 100% Silicone Caulk when I placed the drain in there.

I've been doing the dry-fill-check each time and as of this morning the only area with any dampness is the washer/nut we're talking about. That sounds like a good idea with the caulk on the threads...can I use a bit of plumber's putty to fill the slight gap between the drain stem and the wall of the drain well (cut into the sink)?

Back to the lining everything up, if I can't find the right adaptor for the joint at the wall, can I use 45's between the trap and the sink so that the drain stem connects to the offset correction without a flex pipe? I wish I had my drafting program at work so I could just draw it...I hope you can picture what I'm trying to get at!

We use putty between the drain flange and the top of the sink, not silicone. I've never had luck with the stuff.

As far as the fittings between the trap and the drain, try to use only one fitting if possible. If you use too many, you're going to have draining problems, clogging problems, and then you start running out of room for the trap.


The adapter at the wall is it a 1-1/2" thread or a 1-1/4" thread?

Its a 1-1/4" thread, and of course there isn't much to find in 1-1/4" at the HW store.

Is it allowed to use my heat gun to slightly bend the lead pipe coming out of the wall?

Ben, try a local plumbing supply house, that'll be your best bet for finding 1 1/4" fittings. As for trying to heat the pipe and bend it, that's not a good idea.

Sounds like it's my last bet. We live in a pretty small town, but I am sure one of the towns around us have a well stocked supply store.

Thanks for all of the help folks, I really appreciate it!
