Redoing laundry tub drain from previous owner.double sink drain runs right to left to exit point. Concern is that the Drain pipe runs horizontal with no slope to exit point. Should this cross piece be sloped to ensure good drainage and ensure water gets evacuated. Is there an issue with the way it is currently setup.
