PVC to Brass?

[Magic]

Trying to figure out what I'd need to connect a new slop sink to an existing brass/copper drain. I'd prefer not to cut for a rubber coupler, so trying to see if there is anything that could potentially thread on so I can use the existing p trap.

Rip it out and pvc ftw. Don’t waste time or money.

Can't do anything in the wall in this section so need to make it work from wall out.

Should just be able to thread 1.25 or 1.5" pvc fittings on.

Pvc will thread on. But I say just cut off the trap behind the solder line and then add a new pvc p trap. The tail pipe will slide into the copper and seal with a washer.

I doubt a tail piece will thread on. Take the trap piece to the plumbing store, see what they got. If not,....

Cut the copper stub-out and put a female sweat on threaded coupler (plastic always threads inside metal so it doesn't crack when expanding) the transition to PVC slip joint, then std p-trap

If it is bathroom, it might be 1.25"

1.5"cu x 1.5"FPT
1.5"PVC MPT x 1.5" slip
P-trap kit

I'll grab the links in a seconds.

Here is a sweat on transition.

This is a "maybe" to thread onto the current trap

I'd prefer not to cut for a rubber coupler,

Why not, it's the easiest repair that will work.
Cut copper pipe were it joins copper 90, use fernco coupling to adapt 1.5pvc j trap. Done.

I did this for one of my drains. It's still easy to take apart to clean out.

It works - but if exposed it is ugly!
Make sure it is the armored/banded coupling - code compliant.

One more reason to cut it and add a slip joint. There is no way to ensure the drain of the sink will line up over the trap.

Yeah, I may like that sweat slip joint best. It's just a laundry sink so I don't care what it looks like, but just don't trust the Fernco stuff as much. They always look like a hack repair. I also found a double sided 1 1/2 Sharkbite that should work. I did 1 1/4 to 1 1/2 slip joints in the bathrooms, but those are all moved to PVC. This section of the house has concrete under the floor by garage and can't replace existing piping here easily, especially after tiling already.
