I am replumbing the laundry room in our house. I staged the fittings that I am planning on using to see if it is an okay setup. I am using a 2 inch vent (out the roof) and drain with combination tee wye fittings for the washing machine drain with a separate vent before draining vertically (also a separate sanitary tee for the sink). I am hoping this will provide excellent flow for the washing machine drain. Thanks for any pointers and checking my work/thoughts.

Just realized I need to lose the 22.5s between the traps and vents because I would be creating S-Traps. Anything else?
