Plumbing a dual kitchen sink path
You should be able to move the trap to directly under and between the sinks. In place of the tee going into the horizontal grey pipe install a tee that goes straight down and attach your P trap. Then run your grey pipe horizontally (1/4&quot; per foot slope required) into the top of the drain with a 90 degree elbow.
I don't believe there are any code issues with connecting to the drain with a 90 degree elbow but if so one of the pros here will catch it.
