washing machine drain

[rockgod]

Hi Guys and Gals,
The wife wants the washer/dryer moved upstairs.
The spot it will be going is right next to a sink, and opposite wall of the bathtub drain.
Is it possible to "T" off one of those drain pipes and direct the washing machine to also drain there?
Walls are gutted open, so there's easy access to both.
I know a washing machine discharges a lot of water very quickly, so not really sure if that's even possible with the amount of water that comes out.
Or would I need a dedicated drain for a washer?
We don't really want a utility sink up there.

Thanks...

You should be fine connecting into the drain lines I think. Use a Y instead of a T.

Washer drains need to be 2". Your sink drain is most likely to be 1.5".
