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?
