You know, I give it up. He should just go buy the ****ing nipple when

NYC to find the mythical store that stocks nipples in every length
down to 1/4". If he can't find it, then he should get HD to thread
it to the exact length required, based on what a drain cleaner told
him. Hell there is even general agreement here that from the pic,
it doesn't look 3" in diameter. Then he should hand whatever he buys
to the plumber so that the plumber he's paying $150 an hour can shove
it in, whether it's the right solution or not.

Happy now?

Well, I tried to point out that anything is possible in Brooklyn.
