How Much to Slope the Drain Piping? eHow

In general, plumbing codes require pipes less than 3 inches in diameter to slope a 1/4 inch per foot of run. Codes often allow pipes 3 to 6 inches in diameter to slope an eighth of an inch per foot, and pipes 8 inches or larger are allowed to slope 1/16 inch per foot.

What is the slope of a French drain?What is the slope of a French drain?Remember that a slope of 1/8" per foot is a minimum. In some cases you will want to increase the slope to avoid having to dig very deep French drains. In our example, the end of drainage system close to the house is 54" deep and we would like it to be shallower.Determine the proper depth + slope for a French Drain.
