Can i install a kitchen sink upstairs into washing machine drain directly below

[L-Gordo]

In my basement I currently have a 2" ABS pipe coming out of floor to approximate height of washing machine. I would like to move my kitchen sink in my kitchen to directly above this pipe. Question is what do I need to do to do this I will have the wall open and ceiling open as well I installed a 3" vent pipe into roof when I reshingled can I just tee off at floor and run p-trap and pipe up for washer and run up with 1-1/2" ABS to kitchen sink and continue out to new roof vent? Thanks for adding me to group and hope this is somewhat right. I live in southern Alberta, Canada by the way

Not unless you also run a new vent from the washer in the basement AFTER revising its connection to the stack. Then you do NOT need a vent for the new sink.

I'm not sure if the is a ptrap below cement no odor and I hear bubbling when I blow in pipe wondering if there is a trap there can i run this configuration?

That looks to be a nice drawing of how we would do it.

So it's ok if there's a ptrap under cement and thanks a lot for the quick response Terry

We won't know for sure, but we do know for sure that we want one on the washer done proper.
A trap down in the ground can siphon easily in that circumstance.

People have posted that P-traps under the floor on washer standpipes are permitted in Canada.
