I'm a sort-of handy person and figured I would change the sink in a hall bathroom. The existing sink was installed probably sometime in the 1960s and hasn't been touched. I bought a new sink and pedestal and single faucet and set about learning how.

How in the world do I disconnect this ptrap? The part that pushes up against the wall doesn't budge or turn at all.

Any suggestions on what this and how to disconnect?

Thanks.

Ayuh,..... With a pipe wrench, 'n cheater handle if necessary, loosen the nut lookin' piece on the right in this picture,........

For the trap, it appears to be a collar to the left, put yer pipe wrench on that, 'n turn it off,.....
That should allow ya to pull the trap, 'n the chrome dress collar off the pipe goin' into the wall,....

I would cut it off with a sawsall. It all will need to be replaced. Pull the bonnet off the trap arm and see how it it connected to the drain. It may be a soldered connection.

Hey. I looked around a bit and came across a video showing how could it be unscrewed if its not soddered.

Unfortunately he doesn't show how to do a new hookup of a modern jtrap. If I can unscrew the trap as in the video and find female threads on the bonnet, then what are my options?
Thanks,
Andy

If you find male threads screw on a PVC female adapter. Find female, screw on a PVC male adapter.

I actually just redid the measurements on everything and I may be in luck and can perhaps use the existing JTrap as is. It measures 8 1/2" to the center of the existing drain pipe that drops down from the sink, AND the new sink also has a drain that's 8 1/2" to the center of the drain. I think that means that (like in the video) I can just unscrew the nut, pull out the existing sink and plop the new one onto the existing Jtrap.

I guess I freaked out because I'm afraid of plumbing! Also, the existing sink is old and its drain is 7 1/2" from back to middle, so there's a 1" gap between the sink and the wall. I guess 7 1/2" was the standard back in 1960?

Also - I guess I should clear out the JTrap. Is there a risk that if I try to loosen the clearout cap that the whole thing snaps? It seems pretty sturdy.

I know that it would be recommended to replace all the piping but that would be too big a job for me and I would tackle it with a professional when we eventually redo the bathroom - rip down the tiles and "plaster on chicken wire" walls behind that. I've attached a photo of what is inside the wall. Photo is from the adjacent room which we redid a few years ago. Luckily i have a photo of what to expect.
