        What should be the correct slope of the kitchen drain line? Pipe comes through the floor to basement and runs 24 feet to corner and turns 90 degrees and runs 10′ to vertical pipe up from basement floor. All pipe is 1 1/2″ PVC.

          About ten inches, but 1 1/2″ pipe is really too small for a sink drain that is that long.
