Dishwasher hookup

I am replacing the drain pipes for my kitchen sink. They are currently 1 1/4" and replacing them with 1 1/2''. My problem is with the dishwasher connection. It is currently cut to the 3/4" size. Is this the standard size for the Y branch on the tailpiece? If is is not will I need to replace the hose or is there an adapter?

Your kitchen sink should have had 1 1/2" drains to begin with. You should be able to put the 3/4" tubing on the slanted barbed fitting with no problem.

If the drain doesn't fit the branch tailpiece, here's an adapter designed to repair a cut drain hose:

InSinkErator Dishwasher Connector Kit for InSinkErator Garbage Disposals-DWC-00 - The Home Depot

If you have a garbage disposal, the 3/4" hose should be attached to that. Be sure to knock out the disposal inlet plug.

I did follow those instructions - not sure why they didn't show up. They show up when I preview the post

The second picture, I assume is an "after" picture. It seems to be connected properly. Did you use an adapter or were you able to connect the DW with the existing fitting?

Good Job
Looks professional. Technically your old drain pipes were 1-1/2" slip tube.
The slip tube usually doesn't cause any problems, but your new 1-1/2" ABS is better and has a larger inside diameter.

I'm curious as to what was the problem with the old pipes. From what I can tell both sink bowls should have drained fine.

PS: I have extra turkey if you need it

For the dishwasher I was able to find an adapter at the Wye Connection for the 3/4" tube that I had.

The problem with the old pipe's was it was leaking. The mail problem I could find was that the tailpiece was not that deep into the connector and the seals might not have been good anymore either. Didn't take much of a touch though to pop the tailpiece out of the drain.
