I installed a new vanity and sink, and found that the sink drain doesn’t line up with the p trap (also, incidentally, I’ll need a tailpiece extension – but that’s not my question).
I am trying to move the p trap but the swivel nut on the distal part of the p trap (pictured) is extremely stuck despite channellock pliers. Can I cut the abs just past the elbow and will there be a piece that fits over the cut end? Or should I cut all the way back at the PVC of the sanitary piece?
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.
If you notice at the top, there is a handy dandy nut (if you will) that you can unscrew. Take that off, and you're half way to removing it.
After that, you can unscrew the bottom of the p trap from the rest of the pipe.
Next you will need a PVC P trap kit. Make sure you bring your old pipe to the hardware store and check that you get the correct size (Most kitchen sinks are 1 1/2 or 1 1/4 in.)
Figure out the correct orientation of your p trap. The long pipe included should fit inside of the existing metal pipe nicely. If not, shorten it a little bit with a hack saw. Careful though, the pvc is fragile and easy to crack!
You should be able to save the original section of pipe you unscrewed first if you disconnect it from the sink. (See red arrow) The PVC part of the p trap should screw nicely into the green arrow part of the pipe. You may need to use the original nut, but if that doesn't fit, use the pvc one included in the kit. Make sure it's tight!
Have fun!

It is all glued together, it will need to be cut of at a given spot and glue a wall adapter on the remainder of the cut off piece.
If the white pipe (PVC) is at least 1" beyond the face of the wall, and glue is not smeared over it to any major degree, the pipe can be cut just behind the black (ABS) connector. Clean up the square cut you give it, get rid of any burrs, add PVC primer and glue to the wall adapter and pipe, and join together, holding it in place for a short while , until the glue grabs.
If there is not enough room to get the 1" needed to glue on the wall adapter with the original escutcheon on, when you cut the pipe and remove the escutcheon, this should get you another 3/8" of pipe exposed. Then use a "bell escutcheon" to cover the wall adapter once you connect the sink p-trap.
This means the ABS p trap is useless and a new p trap will need to be installed.
Wall adapters come in different sizes, make sure you get the right size, as well as the p trap.
