I have an ABS p trap that doesn't seem to have any union nuts. Where my finger is pointing is the tail piece nut that I can loosen (and probably remove), but the rest of the p trap doesn't seem to have any removable parts (its a slow draining sink so I want to remove it, check for clogs, and snake it from lower).
House built in 1958 (idk if this is original plumbing). I don't see how the ABS is connected to the PVC drain and I don't see how to remove it besides cutting it off (and then be stuck with whatever pipe I believe is inside/between the pvc and abs). Is cutting the only way to remove this? Should I get a plumber to fix this?

Cutting is the only way to get it off, I doubt that it was original most homes that age were galvanized & cast iron. The supply looks to be galvanized is the reason I would think it’s not original. They didn’t leave any good place to cut it from what I see. You will probably need to remove the expanding foam hopefully there will be a hub or something you can work with to make the new p trap. It may be possible to unscrew from the main pipe but we won’t know until the foam is removed.
