I added an upstairs small bar sink with a mini studor vent above the area where my washing machine drain is located on the floor below in the basement. I would like to tie the upstairs drain into the washing machine drain area. The sink drain comes down roughly above where the standing pipe is located. What would be the best place to cut the upstairs drain into the washing machine drain pipe and be sure everything stays adequately vented? Thank you!
