    Drainage and Sewer Pipe Slope

    A pipe that is too flat will prevent waste from flowing away. It is also commonly thought that pipes that are too steep will allow liquids to flow so quickly that solids will not be carried away. Drainage pipes are usually run at the minimum allowable slope so that ceilings can be kept as high as possible.
