Hello Folks;

Let me know if what I am looking for is obsolete or if you have a suggestion for an alternative. We have a bathroom sink with a 1.25" tailpiece that is badly corroded (>40 years old) and in need of replacement. The corrosion is allowing a leak at the point where the tailpiece connects to the P-Trap. My problem is this: The tailpiece also has a 7/8" dishwasher connector (apparently, this is unusual on a 1.25" tailpiece versus a 1.5" standard part) that is used to connect to an AC condensate drain. In addition to the dishwasher connector, the tailpiece also has the bath stopper connection on the rear.
I can't find a replacement online for a 1.25" tailpiece with a 7/8" dishwasher connector AND the bath stopper all-in-one item.
The P-Trap and drain pipe in the wall are 1.5" and I am wondering if I can convert the tailpiece to a 1.5" setup without causing problems at the sink.

Ive never seen a 1 1/4 threaded w branch tail piece . I built one once brazed it together. no idea if anyone currently makes them As I said this is the first Ive seen . we use slip joint and they require a low rough in . plumber roughed in too high on the original build. i cant tell you where to look obviously plumbing suppliers or manufactures

wrong threads thats a slip joint at the top not tubular brass thread it might work or the tee might be low
I was under the impression that was a branch tailpiece, and not a branch tailpiece extension. I don't know what threads a tailpiece would be expected to have.
