The local code dictates what slope is required for each pipe size. Typically, 3" and smaller DWV pipe should pitch no less than 2% or 1/4" per foot. Larger than 3" should pitch 1% or 1/8" per foot. The pitch also can be dictated by the amount of fixtures connected to a particular pipe. You may be able to pitch steeper with more fixtures connected without changing or increasing the pipe size. This all would have to be checked with the local building and or Plumbing code.
The key steps in drain pipe installation include planning the layout, digging the trench, laying the pipe, connecting the fittings, testing for leaks, backfilling the trench, and ensuring proper slope for drainage.

The gradient of a drain is the slope or incline of the drain pipe. It represents the change in elevation of the drain pipe over a certain distance. A steeper gradient indicates a faster flow of water through the drain.
To install a drain pipe properly, first dig a trench to the desired depth and slope. Place a layer of gravel at the bottom of the trench for drainage. Connect the drain pipe sections using appropriate fittings and secure them with adhesive or clamps. Ensure the pipe is sloped towards the desired drainage point. Backfill the trench with soil, compacting it in layers. Test the drain pipe by running water through it to check for proper flow.
Only if the people want the contents to flow back or forward.
The standard kitchen drain pipe size for residential plumbing systems is typically 1 1/2 inches in diameter.
To effectively install a trencher for a French drain system in your yard, follow these steps: Plan the layout of the French drain system, marking the path where the trencher will dig. Rent or purchase a trencher suitable for the job, ensuring it is the right size and type for your yard. Dig a trench along the planned path, making sure it is deep and wide enough for the drain pipe to fit comfortably. Place the drain pipe in the trench, ensuring it has a slight slope for proper drainage. Fill the trench with gravel or crushed stone to cover the drain pipe and provide proper drainage. Backfill the trench with soil and compact it to secure the drain pipe in place. Test the French drain system by running water through it to ensure proper drainage.
For proper fall. Pipe should slope 1" for every 8'.
