1/8" per foot.

In Tulsa Oklahoma you can, but i would still use 4 in.
Plumbing pitch is the amount of fall you have on your waste. All waste, not on a pump system, has to have fall toward the destination of the waste (septic tank, sewer, etc.) The pitch is basically a downhill tilt of the pipe it requires to drain the liquid and solid waste from the pipe utilizing gravity. standard fall on a waste pipe is 1/8 of an inch per foot. the reasoning behind this is that your solid waste runs with your liquid waste minimizing clogs and optimizing drainage.
The inside diameter of a 4-inch cast iron sewer pipe is typically around 4 inches, but due to the wall thickness, the actual inside diameter is usually about 3.5 inches. This measurement can vary slightly depending on the manufacturer and the specific type of pipe. It's important to consult technical specifications for the exact dimensions.
1/8 inch fall for every foot of run is the ICC code minimum, but I would prefer 1/4 inch fall.
1/8" to 1/4" inch per foot.
1/8 per ft
It really depends on your local building code, but 2% should be the minimum so that your pipe will be self-cleaning.
1/8th per inch
1% pitch is min
1/4" per foot normally
It should be 3" minimum, preferably 4.
.25 per inch per foot
I would use 3 inch for that.
1/16 per inch BUT the pipe must be at least 8" diameter and then only 1440 Fixture units can be connected If you increase pitch to 1/2" per ft then you can go up to 2300 fixture unites
Yes. A reduction fitting can be used.
