I just installed a new sink/faucet today after taking the old one out. The old one drained fine as recently as this morning. The only part of the plumbing that I have exchanged is the pop-up tube and plunger. The rest of the tubing under the sink is the same. After I hooked it all up and ran the water, it would no longer drain. Any ideas? By the way, it says that I answered my own question, and that is not the case.

Most pop ups are controlled by two rods that reach below the sink top, the round rod connects to the drain via a plastic ball and screw on cap. Remove the cap, remove the rod and lift out the plunger. What do you see?

[1flypilot]

Nothing, the pop up is clear.

Plug the hole in the back of the drain with your finger or reinstall just the ball rod. Now pour water down the drain, does it flow properly? You may have not adjusted the vertical rod properly to open the plunger enough to drain. There is a small bolt on the vertical flat rod that allow lengthing and shorting of the vertical rod, adjust to lengthen the vertical rod by about 1/2"

Okay, I've done that, but it seems as though it won't go past the trap. I don't even have the plunger on right now and I can see water just sitting down in the drain.

The trap should always have standing water so don't let that mislead you. That's what makes a trap a trap, the water blocks the sewer gas. Does the sink drain properly now? If so, adjust that vertical flat rod and reinstall your plunger and ball rod. Check that screw on nut for drips when you are donw, it needs to be snug but not too tight to affect the sliding of the ball rod.

Unfortunately no. It's still completely blocked up. And now for some reason when I turn on my cold water valve, it leaks badly. I'm also now leaking water from from the bottom of the basin where the pop-up meets it. There is a big rubber seal there, but it doesn't appear to be working. IT's very snug too. I'm in bad shape.

Hate those drain issues, they can plague me too. We need to start from scratch. Completely remove the trap, place a bucket under it to catch the water, make sure you see nothing in the trap, no lost nuts or bolts. Now, tell me did you seal the chrome drain assembly on the sink side with plumbers putty before you attached the rubber washer and nut from the bottom side.

Plumber's putty sounds like a good idea... (I'm such and amateur)!

The trap has absolutely nothing in it. I did have to slide it back into the mount in the wall so that it would line up with the new drain, but I cut some of the pipe off to account for that. The new drain is about 5 inches closer to the wall than the old sink. I really didn't think any of that would make a difference.

Plumbers putty is a must between the drain assembly and the sink hole. When you tighten that nut under the sink the putty will squish out along the rim inside the sink. Once thatr happens and the nut gets tight you should have a good water seal between the sink and drain. Shortening or lengthening the horizontal lateral pipe after the trap would not cause your issue.

Follow Bobs advice about the drain seal. However, sometimes as the putty sqeezes out the nut will loosen and will have to be snugged up . Check it out in five minutes after you tighten the drain. Good luck, tom

Suggest that you pull that pipe out of the wall and make sure that it is clear. When you shoved it back you may have clogged it with curd from the pipe it's in. Also make sure it doesn't bottom out. If it bottoms out, the end is up against the walls of the fitting. Cut off an inch or so.

Is it possible that the lateral pipe was shoved into the wall so far that it cut off the drainage, or the vent? I would check to see if the lateral pipe only goes into the pipe in the wall by an inch or less.
