It sounds silly but it seems I can't just connect a 1/2" OD / 3/8" ID drainline to my 1/2" dishwasher wye.
I purchased this one which should be 1/2" but I measure roughly 5/8" OD.
Here is a closeup picture:
You can see there is no way I can attach this pipe.
Which part do I need to connect the two?
Also, can it be that they shipped the wrong part? Exactly the one in the link is what I ordered but what I got looks slightly different.
