Anybody see anything wrong with the attached DWV plan? This is just the elevation view but it tells most of the story. Trying to drain a washing machine and kitchen sink into an existing 2" drain line.

24" above the drain line for the washing machine. The washing machine standpipe is 5' away from the vent stack.
