I just changed my sink from 2 sinks (where dishwasher installed to the garbage disposal) to one sink (no disposal). I bought a tail piece ( i think that's what they are called) from Depot that is plastic.
The top screws in...works fine....the "y" goes to the dishwasher drain and appears to be fine and the bottom goes down INSIDE the CPVC, 1 1/2". On the bottom it has the plastic/rubberish stopper and a plastic nut which screws over the CPVC to lock it in.
When the dishwasher drains and ONLY when it drains, I have water pushing back up and out the top of the nuts and leaks out.
I have no clue why. I even tried cutting the plastic tail piece down to a closer size but I screwed that up since when I tighten the nut again it pulls off at the bottom
Any ideas?

I believe you are referring to a slip nut and washer ? Is the flat part of the washer against the nut and the beveled edge pointing down ? Is the surface of the tailpiece perfectly smooth ? Sometimes a ridge is formed when the tailpiece is manufactured and that can cause a leak.

I am not sure what that means you did, but it could mean you need a new tailpiece. WHICH nut is leaking, the top one or the bottom? If it leaks from the dishwasher, it should leak from the sink, if you had enough water in it. We can't tell you why it happens, because it normally only leaks if it is not tight enough.

I have issues with DW tailpieces leaking only when the DW hose is pushing against it....make sure there is no tension from the DW hose pushing against the DW tailpiece

with a plastic flanged tailpiece the "top hat" washer is not really needed.
