This is a remodel issue. Want to run a drain pipe in the crawl
space from a laundry room sink and it will need to be level for
about 18" just before it hits the sanitary tee that leads to the
waste line. The reason is there is a dryer vent in the way. I'm
concerned about how well that section of pipe will drain.

The drain slope is supposed to be a minimum of 1/4" per foot. Maybe
you could move the vent 1/4"?
