Changing out the kitchen sink, and the new unit will be an inch deeper and with offset basins vs the old sink. Existing drain is black ABS — comes out of the wall tee with a close nipple, then a union elbow (male side of union) into a trap, the rest of the P trap into a close nipple to an elbow to a tee and off to elbows for the two sinks (one is a disposal).
I thought I could just redo from the union with PVC, but the clever folks that design such things made the PVC union backwards from the ABS one (female union elbow). I could use just the union elbow part of a PVC trap backwards in a made-up trap, but I think I heard here that made-up traps aren’t code, and besides it’s not clear that the pieces will mate that well.
So, what would you folks do? Fake it with the made-up trap? Try to clean up the wall tee and start anew from there (gluing PVC to old ABS)? Generally things are too close to use a nohub anywhere.

Oh come now, someone's gotta have an opinion.
it must be so cold everybody is staying by the fire?
so here's what i'd do,i'd glue the pvc up and go on,yeah your not suppose to ,but it's been done a million times and only half have come apart! lol
if you can find the glue they make to bond pvc/abs together great,if not what the heck it's in a exposed location if you have to get to it if it starts leaking.i've done it before i knew better and never had one come apart.
how's that for a technical answer. larryif a man speaks in the forest,and there's not a woman to hear him,is he still wrong?
what's wrong with ABS ...
and why is PVC better?
and no, don't glue them together.
two different materials ... "glue" in two different ways.
and even though they sell "transition glue ... for abs to pvc" ... it's not to be trusted.
me .... I'd just rerun with ABS.

ABS is unavailable.

If you can't get the ABS, ream out the close nipple at the wall tee, install a longer nipple and a Fernco, and go from there with PVC.

Well, over lunch, while picking out a strainer basket and looking for a 1.5" reamer (no luck) at HD, I happened on an oppositely-sexed P trap. So apparently I wasted a lot of angst on nothing. Now just gotta make the close joints fit, but should be possible by using some street ells in place of the regular ells in the original.
"looking for a 1.5" reamer (no luck) at HD"
LOL! No kiddin'? They don't have those at HD? ;-)
Glad it's gonna work out for ya the easy way.

Why carry double stock?

well ... for one ...
ABS is generally a better material to use.
but if ABS was already there ... I was wondering why the switch to PVC.
most HO's say they prefer PVC ... without any idea why.
I think it's because the shiny white looks shinier.
PVC "glues" together ... the glue is a "film" ...
ABS "melts" together ... more of a weld.
PVC joints can be broken apart ...
