In order to install a deeper kitchen sink with a disposer, I need to lower the waste outlet so that the disposer does not become the trap.
Since this is 60 year old plumbing, I plan to use 2" PVC, run a new drain through the floor, into the basement, and tie into a cleanout in the original pipe. I will use the existing waste outlet as a vent (since it is vented and will be higher).
My question: How many inches above the floor should I make the center of the waste outlet pipe? Is there any standard?
