You glue it on.
I just replaced a bathroom faucet and had an issue with attaching the drain. The big hose you see is from my air conditioner, so I added that PVC tee piece (original tailpiece was metal and had a metal tee, wouldn't work with popup assembly from new faucet). What you see in the pitcher and in the second pic is the multiple sections of pipe from the P-trap to the drain in the wall.
After I got everything put back together I ran the water for a few min and I eventually got a couple of drops leaking from where the last piece met the wall drain. When I loosened the nuts on the P-trap sections to try to get everything to fit better, that entire section fell off the wall. I'm trying to figure out what to use to seal that last section since it's not threaded, and if I need to be using anything beyond just the washers to seal the locknuts.
Thanks for any advice.
You glue it on.
PVC cement IS meant to be permanent.

It should have a "trap adapter" glued on and the the appropriate fittings used to connect to the trap.
A trap adapter is a fitting that has the correct thread and nut on the outboard end to allow the slip fitting of a trap arm.
It was never glued on in the first place. If the valve handle hits the fitting, it will also hit any extension pipe you install, especially since the coupling you would have to use is the same size as that elbow.
I re-loosened all locknuts, pressed the last piece on the drain tight, and it now clears the valve fine and also has not leaked a drop with 4min of continuous water (including filling up the sink and letting it all drain at once). This should be fine for the next few days until I can get someone to seal it permanently. I checked my other 2 sinks and they had threaded sections at the wall so those faucet replacements should be much easier. Thanks for everyone's help.
You have done the hard work, so why would you have to get someone to glue that fitting in place? Doing that is about a 5 second job.
just never used the primer/cement stuff - seems like there's little/no room for error - i don't mean calling someone out for service, just getting a buddy to come over that has used it before.
Nothing to it! Swab on the primer/cleaner, on both sides of the joint, then swab on the cement. push together while twisting, hold it while it sets... Done!
I recommend using clear primer/cleaner... That purple primer makes a mean stain wherever it drips!
I have to use purple the inspector wants to see it. You don't have to! But you do have to take both steps to get a good connection.
just picked some up during lunch - seems easy enough - got the purple so I'll put down some paper towels - thanks for the tip
