Hello. Is everyone having a good time?

I need to replace a section of drain under the kitchen sink because it has a sticking-up tributary on the back side for the dishwasher drain, and I'm taking out the dishwasher.

I really really don't want to disturb this house of cards under the sink. But I observe that there seems to be a few inches of expanded outside diameter at the input to the trap "U". Does this mean I can just loosen the top and bottom joints, tuck the unwanted pipe down into the "U" and tip it out, and reverse for the new pipe?

I mean, is the purpose or what appears to be a long mating area on the "U" intended to let people telescope a pipe in?

Thanks !!

Cap the tributary off.

Yes I’m have a good time, I’m howling like a coyote then going onto our neighborhood message board and watching all the people post coyote warning threads. 😬
 
That was my first idea, but there doesn't seem to be any manufactured part that would fit, and I would have to buy a $10 jar of glue to use for one 1/2" part and never for anything again.

This knowledge cost me a couple of hours and a gallon and a half of gas shopping.
