Hi everyone, I want to move my washing machine next to the kitchen sink. I live in a concret floor appartment and the kitchen sick is connected to a vertical stack, with a sanitary tee, alone. (See picture) Can i simply add another tee right underneat the sink tee?

If not, how can I connect both to the stack?

If yes, how can i manage to glue everything in place (i cannot move the stack so i would need some sort of mechanical joint?) (Hope i am clear enough!)

The stack is 3 inches diameter. I live in Montreal, Canada

Thanks!

Both a dishwasher and clothes washer have an elevated drain height requirement to prevent syphoning the pumps. I would suggest you use a sanitary "t" into the stack above the one for the sink drain.
