Should have asked here before you installed it. I would have made the double sink 2".

You should have used a bigger font for annotations

1-1/2 double sink above has vent to roof
2 in. washer drain above has vent to roof
2 in shower drain.

Shower should be vented.

James, I thought by code, it is OK to use 1-1/2 for double sink? I can change it. Thank you!!
Reach4, I thought by having the 3 wet vents in the run was proper for the 2 inch shower drain thats about 4 ft from main 3 inch??
