Total Drop vs Pipe Run Length
Formule
## Drainage Slope **Total Drop = Run Length x Slope** The standard slope for most residential drain lines (3-inch and larger) is 1/4 inch per foot. Pipes smaller than 3 inches often require 1/4 in/ft as well, though codes may specify 1/8 in/ft for larger commercial mains.
Exemple Résolu
A 20-foot drain run at the standard 1/4 in/ft slope.
- 01Drop = 20 x 0.25 = 5 inches
- 02In feet = 5 / 12 = 0.417 ft
- 03The outlet must be 5 inches lower than the inlet.
Questions Fréquentes
Why is 1/4 inch per foot the standard slope?
This slope provides enough gravity for solids and liquids to flow together without the liquid running ahead and leaving solids behind. Steeper slopes can actually cause clogs.
What slope do I need for a 2-inch pipe?
Most codes require 1/4 inch per foot for pipes 2-1/2 inches and smaller. Check your local plumbing code for exact requirements.
