How can I safely remove glued Ptraps from wall pipes when replacing faucets and sinks in my house?

I’m in a bit of a pickle here. I was thinking about updating the faucets and sinks in my house, but it turns out the P-trap is glued to the wall pipe. And guess what? All three bathrooms are like that too. Looks like I’ll have to get new P-traps, but I have no clue how to remove the old ones. Any ideas?
So that’s a fantastic connector at the wall. Is the trap glued in there?
Yup, it’s definitely stuck. Won’t move at all.
You have the option to switch out the sinks and faucet and reuse the traps. Remember, if it’s not broken, don’t try to fix it.
However, if you need to dismantle it, there are tools available to bore through the old pipe once it’s been cut. Some individuals opt to use heat to loosen the glue.
Getting a new sink will never align perfectly.
I suggest removing the trim ring with snips. Make some cuts in the P trap adapter, apply heat, and peel it off in sections. Then, clean the PVC and attach a new P trap adapter with glue.
– I agree with this!
You might want to consider hiring a plumber – that slip joint should not have been permanently attached.
I’m pretty sure it was a plumber who caused this problem for me.
I disagree. Slip joint fittings are quite straightforward. Seems more like a homeowner attempting to do plumbing.
To replace the trap adapter, cut it off where the threads end, carefully make slits on the hub, remove the sections using a chisel, and attach a new trap adapter. There are many ways to do this, but this is a quick method that doesn’t involve opening drywall if done correctly.
Absolutely! This is the easiest way to go. It also works on closet flanges.

Perhaps I’m not understanding correctly. Is there a reason you can’t simply unscrew the nut and leave the part that goes into the wall untouched? I’m not seeing the problem here.
You can see at least one is cracked in the picture.
The fitting going into the wall is cracked and there’s no nut to unscrew.
Obviously you would unscrew the nut at the trap. If the pipe extends sufficiently into the wall, then it should be fine. Is there any mention of leaking?
Mentioned that he does not mention any leaks. His suggestion is to eliminate the metal ring, cut off the male threaded coupling, and attach a new one while properly connecting the p-trap. Additionally, he recommends replacing the shut offs and supply lines while underneath.
That is definitely the correct way to do it
Trim off the old parts and keep enough to attach this new piece securely.
Is definitely the winner in making home maintenance simple for homeowners. If not, just call a plumber.
Here’s the trick: it’s simple, quick, effective, and will stand the test of time.
Look up ‘pvc pipe extender’ on Google…
That won’t do the trick. By the way, slip joint is cts, not ips size.
I wonder how they managed to glue that. Slip joint PVC typically doesn’t bond well with regular PVC glue.
Is not completely sure what kind of glue was used, but one thing’s for certain – it’s not coming loose. All the drains in the house were fixed in the same manner, something I’ve never seen before.
If you’re not comfortable doing it yourself, it’s best to call a plumber to replace the adapter. Trying to melt PVC yourself could result in cutting out drywall.
Soak a rag in lacquer thinner, wrap it around the glued joint for approximately 15 minutes, then unscrew the parts you can and use a screwdriver or similar tool in the downspout of the pipe to loosen it. Is the adapter still glued?
Trim it a tad before the trap. Put on a sleeve and extend from there to your destination, then connect with a swivel trap. It’ll simplify things.
Maybe try keeping the part that goes into the wall if there are no leaks, and begin with the elbow.
Why do you feel the need to get new ones? If there are no leaks, no need to change them
Hey, I’ve got 3 bathroom sinks to replace soon and all the drain trap adapters are glued on. I need a simple fix for this.
Hey, just a heads up – if the new sink fits in perfectly, you might not have to replace the pipes at all. But if they don’t line up, cutting PVC and adding to it shouldn’t be too difficult. You might even have to open the wall in some cases, but ideally, everything should line back up. And don’t forget about those flexible pieces that can help if needed.
If you can’t unscrew it from the wall, just cut it off after the glue and then attach a coupling with glue
Just go ahead and leave them there, just tidy them up a bit!
Replace it all! After cutting the horizontal drain, the part connecting to the wall should be able to unscrew from the internal drop.
Appreciate the info! Fingers crossed for a smooth process – this was supposed to be the easy part of the sink replacement.
