Appreciate any insight. Pic below shows a proposed lay out for a basement bathroom. Vent stack is to the far left. You can see the toilet drain and the shower drain is further left out of the picture. Both tie into the stack line below the concrete with the toilet being last in line. The dry fit horizontal 2 inch pvc is where my questions arise. Red circle is a planned washing machine drain which will be on the side of the wall with the HVAC duct work. Yellow circle will be a urinal and black circle is the vanity sink, both in the bathroom. The length of 2 inch pipe from vanity drain to vent stack is 6 feet. There is a 1/4 inch per foot drop in that run and p traps will be added. Does this all look/sound okay? Do I need to include the blue line as a vent which would tie back into the stack? Thanks.
