Kitchen Sink with garbage disposal and dishwasher:
I always rough in a double bowel sink with two 1-1/2" drains. One for the dishwasher and
garbage disposal (Dishwasher discharges directly into the GD). I do this because I figure a
horizontal drain to a Tee would not be enough to handle the DFUs. I allow two DU for the
sink with the GD and two for the dishwasher. I do this because I figure both can be discharging
at the same time. Though I admit this would rarely happen. A fellow plumber says I'm over
doing it. He runs a horizontal drain from the GD into a Tee under the other sink bowel and
roughs in only one 1-1/2" drain.
Am I over doing it?
Your thoughts on best practice?
