I removed the P-trap from underneath my bathroom sink and cleaned out a messy clog. (Blech!)
I thought all was going well, but as I was reinstalling the trap, the metal pipe detached from from the stub of piping leading down from the top of the sink (as in the photo). It felt like the two pieces had been very lightly sealed together.
In your answer, please take into account my basic plumbing knowledge. If you use a term fancier than "pipe," please define it.
Thanks for your help.
A photo would help us visualize the broken part, but provided there's enough surface area, JB Weld should work. It's an epoxy that can join metals.
I would call it a slip x spigot brass drain street ell. Can't say I've seen one until now. More common is the double slip brass drain ell. Hard to say from a photo, but looks like a short horizontal straight piece could be inserted if you had to use a double slip ell. Perhaps the trap U could be rotated away a bit to buy a little extra distance for this.

What you need to replace is the "drain assembly" or "pop up". Here's a link to a sample: http://www.homedepot.com/p/Delta-Push-Pop-Up-Drain-Assembly-in-Chrome-with-Overflow-Holes-72173/204154080
There's every chance you've got a 1-1/4", but maybe it's 1-1/2", so bring your old part with you to the plumbing place or big box.
Don't buy a plastic one. They're terrible.
I'm assuming you've not got a lever assembly to close the drain. (Typically, that's a little rod behind the faucet.) Just be sure to buy one that matches what you have now.
Beyond that, you'll need a big wrench to undo/redo the nut, and some plumber's putty to get back in business. (Some instructions these days suggest silicone around the top of the assembly... I wouldn't do it.)
