Hello!
First of all, this forum has been incredibly helpful as I work through home renovations. Thank you all for your time and advice!
Now onto my specific question - I am moving our washer and dryer to the other side of our laundry room (we are expanding a bathroom, so we have to move it), and there is already a sink drain (1 1/2" pvc) on the wall where we are going to be moving the laundry setup. Unfortunately, it is on the 2nd floor of the house, and changing out the 1 1/2" pipe for a 2" pipe would require cutting a larger hole through the bottom plate on the 2nd floor and 1st floor and running new 2" pipe down into the basement (plus potentially dealing with adding a standpipe that is larger than the space between the wall studs). As a potential solution, I am thinking about just putting in a utility sink and draining the washer into the utility sink. Unfortunately, my wife isn't terribly happy with how a black hose running over this sink would look in the space, so I am trying to figure out ways to make it look better.
I would love to just run the washer drain into the utility sink drain directly, but I have read that if the utility sink doesn't use 2" pipe, I wouldn't be code compliant. I think my big question has to do with this reasoning. I understand that the 1 1/2" sink drain might not be able to handle the new washer discharge and would back up, but wouldn't the backup simply go up into the sink and drain at its own pace (similar to if we were to run the drain hose over the edge of the sink)? Or, would there be issues with the discharge getting pushed back to the washer? Also, I assume the 2" requirement (if I were to drain directly into the sink drain) includes the entire length of the pipe down to the main stack, correct? I can't just use 2" on the utility sink drain and then hook it into the 1 1/2" pipe that goes down the walls?
A few other details that might be helpful:
I am also open to other ideas if you have them

A few other details that might be helpful:
- The sink drain is vented.
- There is nothing else on this drain line until you get down into the basement. It goes 100% vertically from the sink to the basement (probably 15 feet), then runs horizontally and hooks into a line that also has the kitchen sink on it.
